Summary

The following is a report on the products and technologies related to drive systems, motors (parts, materials), motors (coil winding machines) and machining technologies exhibited by 27 manufacturers at the 2nd EV & HEV Drive System Technology Expo ("EV Japan") held in Tokyo Big Site on January 19-21, 2011.

EV Japan this year saw a significant increase in the number of manufacturers from varying categories including motors, motor parts, materials and manufacturing equipment, and machining technologies. Among those that exhibited machining technologies, ten small- to medium-sized companies exhibited their original machining technologies in the booth of NC Network Co., Ltd., an engineering trading company that sells their products (only six in the previous EV Japan; four of them returned to the show this year).

Exhibits of rechargeable batteries, next-generation batteries, chargers, and related parts and materials will be introduced in Report 2.
