What are the torque and the positioning torque of a stepper motor?
What is the meaning of the fixed torque?:When the stepper motor is not energized, the stator locks the rotor torque.Popular point of view: to maintain torque is the motor in power, but not running, the torque required to rotate the motorThe positioning torque is the torque required by the motor to rotate the motor without electricity
Because the output torque of stepping motor is decaying with the increase of speed, the output power also varies with the increase of speed, so keeping torque is one of the most important parameters of stepping motor. For example, when people say that 2N.m stepper motor, in the absence of special instructions, refers to the torque of 2N.m stepper motor.When the stepper motor is not energized, the stator locks the rotor torque.
Refers to the stepper motor power, but there is no rotation, the stator locked rotor torque. It is one of the most important parameters of the stepper motor. The torque of the stepper motor is close to the torque at low speed.
