Adapting to challenging magnetic environments: MT73xx 3D dual-output Hall latches from NOVOSENSE enable precise automotive motor control

　　The NOVOSENSE MT73xx series dual-output Hall latches, based on 3D Hall technology, support SS (Speed & Speed) or SD (Speed & Direction) dual-channel outputs and complies with Automotive Grade 0 standards. Ideal for motor control systems such as power windows, liftgates, and sunroofs, this product family enhances the accuracy and stability of speed and position detection, optimizing overall in-vehicle comfort.　　In motor control systems, precise detection of speed and direction signals directly influences system response speed and operational stability. Traditional solutions typically rely on a combination of two separate Hall latches, requiring high magnetic ring installation precision. This often leads to issues such as signal phase deviation, poor synchronization, and structural complexity.　　Integrates a 3D Hall sensing structure with inherent orthogonal output characteristics, the MT73xx series can simultaneously deliver dual-channel speed signals (SS output) with a 90° phase difference or speed and direction signals (SD output), making it widely suitable for “speed-direction” detection applications. This design reduces dependency on precise positioning of magnetic poles, mitigates dual-channel phase deviation, simplifies system architecture, and improves overall system stability, providing a more flexible and reliable solution for motion control detection.　　Compatibility with diverse magnetic ring configurations enabled by VHS technology　　To achieve high-precision 3D sensing, the MT73xx series adopts NOVOSENSE’s proprietary VHS (Vertical Hall Sensor) technology. Through combinations of XY, YZ, and XZ axial sensing, any two axes naturally deliver orthogonal outputs, enhancing signal synchronization.　　Additionally, the MT73xx series offers excellent compatibility with various magnetic ring configurations – whether axial, radial, or irregularly shaped magnets – maintaining robust duty cycle performance. This allows customers to adapt designs flexibly depending on magnetic ring characteristics and installation environments, further reducing development complexity and tuning costs.　　Dual-output design for optimized system integration　　Regarding system integration, the MT73xx’s dual-output capability allows it to replace traditional single- or dual-Hall solutions by directly transmitting SS (Speed & Speed) or SD (Speed & Direction) signals to ECU, minimizing the requirements for peripheral redundant position sensors.　　This approach not only saves PCB space and simplifies structural layouts, but also enhances solution integration, offering greater design flexibility for innovative applications in motor control and intelligent cockpit systems.

Nidec Develops New Automotive Air Suspension Motor

　　Nidec Corporation (TSE: 6594; OTC US: NJDCY) (the “Company”) today announced that Nidec Motor (Dalian) Limited (“Nidec Motor (Dalian)”), a corporation that the Company owns in China, has developed a new air suspension motor for automobiles.　　By utilizing its long-nurtured technologies for brake and power steering motors and other drivetrain products, Nidec Motor (Dalian) has developed this latest air suspension motor. Compact, durable, and highly responsive during start-up, this product drives the air compressor, the component that supplies the air tank with compressed air.　　Conventional suspension systems use a coil spring to absorb vibration and shock just to keep a car from swaying. Air suspension systems, on the other hand, can fine-adjust the car’s height with pneumatic pressure. This feature not only improves the car’s passenger comfort, it also improves the car’s driving performance based on running circumstances as well. For example, air suspension systems lower the car’s height during high-speed running to reduce air resistance, while increasing the car’s height during off-road running to enhance its ground-covering performance.　　Main features:　　1. It’s compact: With the ultimate-level torque, the motor is compact enough to be installed in a limited space. The strong magnetic structure guarantees this compact and efficient motor’s excellent performance.　　2. It’s long-life: The brushless design of this motor makes it a durable product. With the use of electronic commutation, this motor better reduces risks of defacement of commutators and mechanical trouble, and secures a longer life, than its brushed counterparts.　　3. It starts and responds quickly: The use of electronic commutation enables the motor to start and drive the compressor quickly, and to secure less start-up friction and better power-up responsiveness than its brushed counterparts.　　As the world’s leading comprehensive motor manufacturer, Nidec stays committed to utilizing its technologies to make light, thin, short, and small products, technologies to improve efficiency, and technologies to secure high-level control, to propose revolutionary solutions that contribute to the evolution of automobiles.　　Nidec Motor (Dalian) Limited:　　Nidec Corporation’s first company to be established in mainland China in 1992, Nidec Motor (Dalian) Limited develops, produces, and sells automotive brakes, drivetrain units, steering systems, and other motors for the car’s main functions, as well as motors to improve passenger comfort (air suspension, sunroof, seat adjustment, column adjustor, and other applications). With its R&D and production technologies inter-integrated, Nidec Motor (Dalian)’s departments engage in simultaneous business activities to send out “easy-to-produce, high-quality” products into the world.

Nidec’s Motor for Battery-assisted Bicycles is Adopted for Use in Taiyo Yuden’s Regenerative System that Keeps Them Running for 1,000km per Charge

　　Nidec Corporation (TSE: 6594; OTC US: NJDCY) (“Nidec” or the “Company”) today announced that a motor that it developed for regenerative system-based battery-assisted bicycles has been adopted for use in FEREMO™, the regenerative power assistance system*1 that Taiyo Yuden Co., Ltd. (“Taiyo Yuden”) produced keeps a bicycle running for up to 1,000km on a single charge*2　　FEREMO™, the regenerative power-assisted system that Taiyo Yuden developed, uses its power-assisting motor as a generator when the person on a bicycle puts on the brake or has his/her feet off the pedals, to collect and reuse motion energy.　　This feature enables FEREMO™ to enjoy a significantly longer per-charge running distance, or up to 1,000km, than conventional power-assisting systems. In addition, with speed suppressed while the regenerative system is on, one can ride a bicycle safely even on a downhill.　　Nidec’s power-assisted bicycle motor installed in FEREMO™ was designed exclusively for the system. While conventional power-assisting systems merely engage in powered operation (i.e., driving a motor with battery-generated electricity), this new motor operates as a generator when a bicycle decelerates, engaging in regeneration (i.e., rotating a motor with external power to generate electricity). In comparison with the Company’s other existing motors, this latest model boasts 30% more regenerative electric power, which is an industry-leading power generation efficiency, to help FEREMO™ achieve the 1,000km travelling distance. Furthermore, unlike assistance-only motors, load is constantly on the motor, making it more durable, low-noise, and radiation-efficient than conventional models.　　As the world’s leading comprehensive motor manufacturer, Nidec stays committed to developing products with its technologies to make light, thin, short, and small products, as well as productivity enhancement and control technologies; and to proposing, at an overwhelming speed, revolutionary solutions that contribute to the lives of people around the world.　　*1: FEREMO™  are Taiyo Yuden Co., Ltd.’s registered trademark or trademark for use in Japan　　*2.

NOVOSENSE Launches NSI22C1x Series Isolated Comparators to Help Create More Reliable Industrial Motor Drive Systems

　　NOVOSENSE announced the launch of its NSI22C1x series isolated comparators based on capacitive isolation technology, which include NSI22C11 isolated single-ended comparators for overvoltage and overtemperature protection and NSI22C12 isolated window comparator for overcurrent protection. The NSI22C1x series can be used for overvoltage, overtemperature and overcurrent protection of industrial motor drives, solar inverters, uninterruptible power supplies and on-board chargers. While improving system reliability, it supports higher power density system designs and simplifies peripheral circuits to reduce the size of system protection circuits by 60% compared to the traditional discrete scheme.　　Industrial motor drive systems, for example, are developing towards higher efficiency, higher power density and higher reliability. At the same time, with the application of wide bandgap semiconductors represented by SiC and GaN in power devices, higher requirements are placed on system reliability, especially the response time of overcurrent and short-circuit protection. The NSI22C1x series isolated comparators launched by NOVOSENSE can meet the growing demand for high reliability, high efficiency and compact design in industrial motor systems.　　Ultra-low propagation delay and ultra-high CMTI support higher power density designs　　The application environment of industrial motor drive systems is complex and harsh. Unexpected conditions such as bridge arm shoot-through, phase-to-phase short-circuit and ground short-circuit may occur, resulting in excessive current flowing into the motor drive system and causing damage to the driver. Traditional overcurrent detection design uses a discrete scheme of general-purpose comparators and optocouplers, with a response time of 3~5µs. As power devices shift from silicon-based IGBTs to third-generation semiconductors SiC and GaN, their short-circuit withstand time has been shortened to less than 1µs, which can no longer be met by the traditional scheme.　　VIN(CH1), VOUT(CH2), VREF=320mV (protection threshold), NSI22C12 propagation delay measured 144ns　　Meanwhile, general-purpose op amps/comparators have limited common-mode voltage tolerance and are limited in applications such as DC+ overcurrent and phase current overcurrent detection. If only DC- overcurrent is monitored, the fault condition of the motor shell being shorted to ground cannot be covered. NOVOSENSE's NSI22C12 isolated comparators provide a single-chip isolated overcurrent protection scheme that can cover a more comprehensive range of fault scenarios, support a maximum propagation delay of 250ns and bi-directional overcurrent protection, and provide CMTI (Common-Mode Transient Immunity) of up to 150kV/μs, which greatly improves system reliability and supports the adoption of higher power density designs for customers' motor drive systems.　　VIN=0V, VOUT(CH1), CMTI(CH3)=150kV/μs, VOHmin =2.40V>0.7*VDD2(VDD2=3.3V)　　When the primary and secondary sides of NSI22C12 withstand a CMTI of up to 150kV/μs, the output still maintains a high level and overcurrent protection will not be mistakenly triggered.　　Simplified system designs reduce the size of system protection circuits by 60%　　In industrial motor drive systems, the bill of materials for the overcurrent protection scheme based on general-purpose comparators and optocouplers is up to 27 pieces, and the system failure rate of peripheral circuits consisting of numerous discrete devices is relatively higher. NSI22C12 integrates a high-voltage LDO with a primary-side supply range of 3.1~27V, which can help customers reduce extra step-down regulators; NSI22C12 also integrates a 100μA ±1.5% high-precision current source, which can help customers achieve ±20mV~±320mV bidirectional threshold adjustment with only a single resistor on board.　　With the support of a highly integrated design, the overcurrent protection scheme using NSI22C12 isolated comparators can reduce the bill of materials to 11 pieces and reduce the size of system protection circuits by 60%, greatly reducing the use of discrete devices, simplifying the system design, and further improving system reliability. At the same time, in some systems with fast protection requirements, using NSI22C12 isolated comparators can reduce the use of high-speed optocouplers and provide customers with more cost-effective design options.　　Typical application block diagram of NSI22C12 for bus/phase current protection in motor drive systems　　Packaging and selection　　NSI22C11 isolated single-ended comparator and NSI22C12 isolated window comparator NSI22C12 are available in both SOP8 package (for basic isolation) and SOW8 package (for reinforced isolation). In addition, the NSI22C1x series supports a wide operating temperature range of -40°C to 125°C. Currently, the industrial version of the NSI22C1x series has been put into mass production, and the AEC-Q100 automotive version is expected to be launched in the second half of 2024.

AIR Partners with Nidec to Develop Customized eVTOL Motor for AIR ONE Production Model

　　AIR, creator of eVTOLs for the consumer market, today announced its partnership with Nidec Motor Corporation, a leading manufacturer of commercial, industrial, and appliance motors and controls, to develop the motor for the production model of AIR’s two-seater eVTOL (electric vertical takeoff and landing) aircraft, AIR ONE. The two companies will design and develop a motor specifically for mid-sized eVTOL aircraft, ultimately filling a void in the burgeoning AAM (advanced air mobility) industry.　　“AIR ONE”　　This collaboration marks a significant step towards the future of aviation and the mass production of consumer eVTOL aircraft for the very first time. Nidec, an industry veteran of fifty years and among the world’s largest electric motor manufacturers, will work with AIR to develop an efficient motor customized to support the single-charge journeys of up to 100 miles that AIR ONE offers. Funded by the BIRD Energy program of the BIRD Foundation (Israel-U.S Binational Industrial R&D Foundation) to support innovative joint clean energy U.S.-Israel collaborations, the resulting enhanced-efficiency motor will be incorporated into AIR ONE’s continued flight testing and eventually into AIR’s production practices.　　“The motor represents the heart of any vehicle. It’s thrilling to partner with Nidec, a pillar of market excellence, to advance the production of AIR ONE,” said Rani Plaut, CEO and co-founder of AIR. “Not only does this partnership represent a major turning point for the AAM industry as a whole, but it also specifically paves the way to fulfilling AIR’s mission and the dream of personal flight.”　　“We’re excited to merge Nidec’s motor expertise and global manufacturing capabilities with AIR’s revolutionary eVTOL to deliver advanced motor capabilities to the individual consumers who wish to fly,” said Vincent Braley, CEO of Nidec Aerospace. “Nidec’s uncompromising quality standards and technical capabilities have been trusted implicitly for decades throughout industries, and we’re ecstatic to create an aerospace centric motor, designed for safety, that AIR ONE customers know they’ll be able to depend on.”　　The partnership is the latest milestone for AIR, which announced its participation in the U.S. Air Force’s prestigious AFWERX Agility Prime program last month to drive flight testing and additional eVTOL R&D efforts in the United States. Previous full-scale, full-weight flight tests, including hover-to-cruise and cruiseto-hover transitions, prove AIR’s status as an industry leader, flying ahead of the curve on these milestones. With over 1,000 AIR ONE vehicles reserved via preorder and a waiting list, AIR plans to deliver the first batch of aircraft to consumers following aircraft certification.　　About AIR　　AIR is revolutionizing everyday mobility for everyday people, empowering individuals to seize the power of personal flight. Combining aerospace innovation with the maturity of automotive technology and uncompromising safety standards powered by proprietary fly-tech, AIR's first-of-its-kind eVTOLs for personal use offer the ground-breaking opportunity to easily "drive the sky." Founded by Chen Rosen, Netanel Goldberg and Rani Plaut, based in the green fields of Pardes Hanna, near Tel Aviv, AIR is paving the way for a cleaner, more thrilling future of mobility, affording everyone the freedom to fly.

AMEYA360：What Is a Brushless DC Motor

　　Brushless DC motors meet this requirement. As Fig. 2.22 shows, the rotor of a brushless DC motor is a permanent-magnet rotor and the stator is a coil.　　The difference from the DC motor (where the coil rotates) is the part that rotates. The principle of rotation, output characteristics, and other basic characteristics are virtually the same between them.　　Since the coil does not rotate, brushes and commutators are not necessary. However, it is necessary to devise a means of detecting the rotor's rotational position to switch the current to the coil.　　To create a brushless motor, it is necessary to switch the current using a method that is different from the one used in connection with mechanical contacts. Consequently, to drive a brushless DC motor, we switch the coil current by using a drive circuit configured with a semiconductor device instead of using mechanical contacts.　　The brushless DC motor has been developed along with the development of semiconductor device, and it cannot rotate without its dedicated drive circuit.　　A brushless DC motor is occasionally called a brushless motor ("DC" is omitted).　　Fig. 2.22 (a) Structure of brushless DC motors　　(1) Stator (Left) and rotor (Right) The concentrated winding method is more popularly adopted than distributed winding. The permanent magnet used on the rotor surface is made of neodymium.　　Fig. 2.22(b) Example of brushless DC motor　　(2) Structural example of brushless DC motor. A position detection sensor is seen in the casing to the right.
