Buying Guide

Match controller type to motor

Choose a stepper driver for NEMA stepper systems, a VFD for AC induction motors, and an integrated gearbox controller for applications needing high torque at low speed

Confirm voltage and phase compatibility

Verify whether the controller supports your supply (single-phase 200–230V vs. three-phase) and the motor horsepower or current requirements

Check control and interface options

Look for interfaces you need—LCD displays, analog/PMW inputs, or encoder feedback—to ensure precise speed and torque control

Evaluate mounting and mechanical fit

Consider physical form factor and gearbox integration for geared AC motor units to guarantee proper mounting and shaft alignment

Assess documentation and support signals

Prefer controllers with clear wiring diagrams, parameter lists, and community or manufacturer support, which reduce setup time and troubleshooting
