The holding torque of a stepper motor is also called static torque. It is the maximum torque applied to the shaft of a powered stepper motor without continuous rotation under rated static current. In layman's terms, it is the torque of the motor when it is stationary under power. It is one of the most important parameters of a stepper motor. Usually, the torque of a stepper motor at low speed is close to the holding torque.
Since the output torque of a stepper motor decays with increasing speed, and the output power also changes with increasing speed, the holding torque has become one of the most important parameters for measuring stepper motors. For example, when people say a 2N.m stepper motor, it means a stepper motor with a holding torque of 2N.m unless otherwise specified.
For conventional open-loop stepper motors, the recommended optimal operating speed is 200-400 revolutions per minute. At this speed, the motor has the best torque and various performance. If you want high speed, you can choose a high current, which is more suitable for high-speed operation.
