Stepper Drive

We-iTech offers wide choices of open loop and close loop stepper drives. It can control stepper motors through simple step and direction control and EtherCAT/CANbus/Modbus network.

Based on new 32-bit DSP technology, open loop stepper drive are designed for various models of 2 phase and 3 phase 28~130mm (NEMA 11~52) hybrid stepper motors which current are from 0.5A~11.2A. With servo-similar control circuit and superior software algorithm, KD series drive has superior performance in smoothness, noise and vibration. Smooth and accurate current control technology greatly reduces motor heat.

A closed-loop stepper drive can receive the encoder feedback from close loop stepper motor, so it can detect commanded target position and real-time position of the motor shaft. That’s why close loop drive can work like servo system. This closed-loop system solved the step loss problem in open loop stepper systems, but it’s cost is less than AC servo system. Therefore, We-iTech close loop stepper drives are widely used to upgrad open-loop systems, or replacing servo applicaitons which speed are within 1000RPM.
