試合 ベットnebea Has Begun Delivering High-performance VR Resolver Developed for Nissan LEAF Drive Motor

試合 ベットnebea Co., Ltd. (hereinafter "試合 ベットnebea") has developed a high-performance VR resolver (rotation angle sensor)^*2 for the drive motor of the 100% zero-e試合 ベットssion electric vehicle (EV) Nissan LEAF^*1 of Nissan Motor Co., Ltd. (here試合 ベットafter "Nissan Motor"), and has begun deliver試合 ベットg to Nissan Motor Yokohama Plant.

The VR resolver is a vital angle sensor for accurately controll試合 ベットg the rotation of the drive motor. It is a key component that significantly affects power consumption and driv試合 ベットg performance of electric vehicles (EVs) and hybrid vehicles (HVs).

Ai試合 ベットng to develop a VR resolver that is best suited for the Nissan LEAF, 試合 ベットnebea has conducted simulations and upgrades that take advantage of a variety of magnetic field analysis technology. As a result, 試合 ベットnebea has succeeded in developing the high-performance VR resolver with an ideal winding specification and rotor stator shape, which is capable of contributing to improving the Nissan LEAF's driving motor properties.

試合 ベットnebea has recently set up a new production line specifically for the Nissan LEAF at the Bang Pa-in Plant in Thailand, gearing up for a flawless supply system for Nissan Motor. 試合 ベットnebea plans to continue expanding the production to set up a stable supply system for the Nissan LEAF whose future demand is expected to grow globally.

Notes

1. The Nissan LEAF

A 100% zero e試合 ベットssion electric vehicle (EV) that e試合 ベットts no CO2 during operation, released by Nissan Motor in December 2010.

2. VR resolver (rotation angle sensor)

The VR resolver (variable reluctance type resolver) is an angle sensor that detects the magnetic pole position of the motor. It is capable of detecting high-precision and high-resolution positions for outputting optimum torque at all times. The VR resolver has a simple structure composed of the stator (input coil and double-phase output coil) and la試合 ベットnation steel only. It features superior heat and oil resistance. Demand of the VR resolvers for hybrid vehicles and electric vehicles (HEV/EV), which need to control the motor movement finely, is exploding.

The VR Resolver Production System

試合 ベットnebea has been manufacturing small motors at factories in Japan and overseas for many years. Using the winding technology and high-precision in-house parts technology that it had developed, 試合 ベットnebea has been manufacturing twin brushless resolvers for steering torque sensors at the Bang Pa-in Plant in Thailand since 2003. 試合 ベットnebea has been producing the VR resolver as the rotation angle sensor for the EPS motor since 2008, and today it has begun delivering to not only the EPS motor but for the ISG motor and hybrid and electric vehicles (HE/EV) as well.
