Cogging Torque and Torque Ripple Test Systems

  • ATM series for small motors

    We measure cogging torque characteristics of the motor by rotating it by 360° in a non-excitation state while measuring torque and rotation angle.
    We measure torque ripple characteristics of the motor by rotating it by 360° in an excitation state while measuring torque and rotation angle.
    For high-quality motors designed to operate quietly with low vibration, cogging torque and torque ripples must be reduced to very low levels to minimize vibrations.
