Product Features

For travelling / open type
AC controller (S type and L type)

We started the development and serial production of DC motors and controllers for battery forklifts in 1960's. We provide serial production lineups of DC motors and AC motors (IM and PM) and have many supply records. In recent years, we have improved vehicle control and achieved improvement of power consumption by 20% for customers adopting the new PM motor and control. We listened to customer requests (output characteristics and dimensions) and propose appropriate product design for battery powered vehicles.

  • Appropriate product design

Applications and Solutions
