The operation of a stepper motor needs to be driven by a pulse-distributing power-type electronic device, i.e. a stepper motor driver. It receives pulse signals from a control system and distributes the pulses in sequence according to structural characteristics of the stepper motor to realize control of angular displacement, rotation speed, rotation direction, brake load state and free state. Each time the control system sends a pulse signal, the driver can drive the stepper motor to rotate by a step angle. The rotate speed of a stepper motor is proportional to the frequency of pulse signals. The amount of angular displacement is related to the number of pulses. When the stepper motor stops rotating, two states below can be generated: brake load leading to maximum or partial holding torque (generally called brake hold, without electromagnetic braking or mechanical braking) and the rotor in a free state (driven by external thrust force to easily rotate).The stepper motor driver must match the model of the stepper motor. Otherwise, both of them may be damaged.
