1.Positioning or residual torque: when there is no current passing through the winding, the torque required to make the output shaft of the motor rotate. 2.Driver: an electrical control device used to run the stepping motor. This includes power supply, logic programmer, switching element and a variable frequency pulse source which determines the step rate. 3.Dynamic torque: the torque produced by the motor at a certain step rate. The dynamic torque can be expressed by PULL IN torque or PULL OUT torque.
