About Us:
We specialized in investigating, building and servicing electrical motors, gearbox and large precision gears with the modest modules.
Right after many years of growth, we have an independent merchandise layout and the R&D group, provider group, and specialist high quality manage group.
What is actually much more, we have two joint ventures. One is located in HangZhou, which makes hybrid stepper motor, cherished linear stepper motor, brushless DC motor, servo motor, stepper motor driver, brushless motor driver, encoder and brake.
Another 1 is situated in HangZhou, which makes DC equipment motor. The manufacturing facility has dozens of CNC machines and large precision examination gear, implements the process management and automatic procedure in most producing method.
We also have two cooperation factories. 1 is producing AC reversible synchronous motor and AC servo motor, the other one is producing linear everlasting stepper motor, long term stepper motors.
