Stepper Motor

Testing Systems for Stepper Motors

The Motomea Stepper Motor Testing System is a turnkey system for testing stepper motors. It can test many important characteristics, including: Pull-in torque, Pull-out torque, Torque vs Angle, Holding torque, Detent torque, Angular accuracy, Step damping, Stepper motor temperature, Stepper motor performance (Torque-Speed-Efficiency), and more.

Using universally proven technology, the Motomea system allows precision bench-top measurements, supporting engineers in their efforts to continuously improve their stepper motors.


The stepper motor’s driver connects to the system (input DC can be tested by a DC power analyzer), and the motor is mounted onto the loading table by a double-disk coupling. The system will give the required clock pulse to the stepper motor’s driver, to work at the required testing condition. When testing highly accurate angles, the ROD angle sensor will be used on a separate dedicated test stand.
