We can manufacture products according to customer's requirements

About Us:

We specialized in researching, developing and servicing electric motors, gearbox and high precision gears with the small modules.

After years of development, we have an independent product design and the R&D team, service team, and professional quality control team.

What's more, we have two joint ventures. One is located in Changzhou, which produces hybrid stepper motor, precious linear stepper motor, brushless DC motor, servo motor, stepper motor driver, brushless motor driver, encoder and brake.

Another one is located in Shenzhen, which produces DC gear motor. The factory has dozens of CNC machines and high precision test equipment, implements the process management and automatic operation in most producing process.

We also have two cooperation factories. One is producing AC reversible synchronous motor and AC servo motor, the other one is producing linear permanent stepper motor, permanent stepper motors.
