The static torque of stepper motors is called holding torque

What is the holding torque?


  The holding torque refers to the moment at which the stator locks the rotor when the stepping motor is energized but does not rotate. It is one of the most important parameters of a stepper motor. Usually, the torque of the stepper motor at low speed is close to the holding torque.
 

  Since the output torque of the stepping motor is continuously attenuated with the increase of the speed, the output power also changes with the increase of the speed, so the holding torque becomes one of the most important parameters for measuring the stepping motor.
 

  When people say that the 2N.m stepper motor, unless otherwise specified refers to a stepper motor which the holding torque is 2N.m.
