Nidec launches new motor products for automotive air suspension systems

Nidec Motor (Dalian) Co., Ltd., a local subsidiary of Nidec Corporation in China, has launched a new motor product for automotive air suspension systems.

Nidec Motor (Dalian) has developed motor products for air suspension systems using its product technologies in the fields of brake motors, power steering system motors, and other transmission systems over the years. This product has the characteristics of "small size, long life, and high-speed starting responsiveness". As the core component of driving the air compressor, it supports the air compressor to deliver compressed air to the air tank.

The traditional suspension system can only absorb vibrations, attenuate impacts and reduce vehicle shaking through coil springs. The air suspension system can not only use air pressure to adjust the height of the vehicle body and improve driving comfort, but also lower the chassis and reduce air resistance when the vehicle is driving at high speeds. It can also raise the chassis and improve passability when driving off-road, etc., and adjust the height of the vehicle body according to the vehicle's driving conditions.

【feature】

① Small size: Miniaturization is achieved by pursuing high torque density. It can be installed in a limited space. The high magnetic performance magnetic structure is adopted to achieve small size and high efficiency while ensuring performance.

② Long life: The long life design of brushless motor is adopted. The electronic commutation reduces the possibility of commutator wear and mechanical failure compared with brush motor, achieving longer life.

③ High-speed starting responsiveness: The starting characteristics of the compressor are driven quickly. The electronic commutation is adopted, and compared with the brushed motor, the starting friction is smaller, and the starting response is faster.

【Specification】

In the future, as a world-leading integrated motor manufacturer, Nidec Group will continue to develop products that utilize lightweight, short, energy-efficient, and control technologies, and provide customers with innovative solutions that will help promote the development of the automotive industry.

【Production Factory Introduction】

Nidec Motor (Dalian) Co., Ltd. is a local legal entity established by Nidec in mainland China in 1992. It is mainly engaged in the development, production and sales of motor products related to major functions such as automobile braking, transmission, steering, and various motor products that improve automobile comfort (for air suspension systems, sunroofs, seat adjustments, column adjusters, etc.). In addition, it integrates R&D and production technologies and provides "easy-to-produce, high-quality" products to global customers through linkage between various departments.

In terms of development, the motor development department of Nidec Motor (Dalian) has more than 15 years of experience in automotive development. We have developed a magnetic platform for brushed and brushless motors from small automotive motors (tens of watts) to high-power motors for electric power steering (hundreds of watts), and have an environment for developing any automotive actuator. In addition, it has magnetic analysis and simulation capabilities, and can be customized according to customer needs. In addition, the company also has the mold design and maintenance capabilities for stamping products and resin molded products. By implementing "synchronous development activities" (i.e., product development and manufacturing site linkage development), the R&D cycle is greatly shortened while achieving excellent mass production quality. In addition, R&D personnel also personally visit suppliers and participate in discussions on manufacturing activities on the manufacturing front line to avoid "imbalance, overload and waste" in design, so that the component structure and tolerance design are more rational, and the quality and price of components are more competitive. At present, Nidec Motor (Dalian) is committed to the research and development of motors for electric power steering (EPS), hydraulically controlled brake One-Box motors, brake-by-wire (BBW) motors, electromechanical brake motors, and electric drum brake (EDB) motors, and is constantly expanding its product lineup to provide strong support for the development of future intelligent integrated wire-controlled chassis.

In terms of production, Nidec Motor (Dalian) has been providing products to many domestic and foreign customers for many years. It has rich experience in mass production and the ability to independently design production lines. It can choose production lines according to the annual output. For products with a large annual output, an automated production line design is adopted; for products with a small annual output, a co-linear island production line is adopted. Including stamping production lines, forming production lines, shaft precision processing production lines and mold design centers, we fully utilize the experience accumulated over the years in self-made parts, and strategically strengthen the cooperative relationship with suppliers to build a stable and competitive product supply system in the volatile Chinese market.
