The brake stepper motor is a special type of motor that is equipped with an encoder, a reducer and a brake device on the basis of a stepper motor. ‌The main feature of this motor is that when the power is off, the brake device tightly holds the motor shaft to achieve the locking function of the motor in the power-on or power-off state. The design and application of brake stepper motors are intended to improve the application range, performance, etc. of the motor, while ensuring that the motor can be accurately stopped and positioned when needed.
