An electric motor is a device that converts electrical energy into mechanical energy. The starting process of the motor will undergo a state transition from static to dynamic; after the motor is powered off during operation, it will undergo a transition from dynamic to static due to inertia. Most equipment has no requirement for the length of time from moving to static, but some equipment such as elevators, cranes, automated production lines, etc. must be stopped within a very short period of time after power failure, which introduces our topic today, motor brake control. The electromagnetic brake is generally installed at the non-shaft extension end of the motor. The motor shaft and the spline (external spline) are connected through an ordinary flat key, and then connected to the brake disc through a spline sleeve (external spline). When the motor is energized, the excitation coil of the brake is synchronously connected to the power supply. Under the action of electromagnetic force, the yoke attracts the armature to separate the armature from the brake disc, releasing the motor shaft, and the motor shaft with the brake disc runs normally or starts; When the power is off, the excitation coil loses power, and the electromagnetic force of the yoke attracting the armature disappears. The return spring pushes the brake disc and the armature to separate, forcing the brake disc and motor flange to generate friction torque, quickly stop the motor shaft.
The electromagnetic power-loss brake is an electromagnetic brake, which is composed of three parts: excitation, magnetic conductivity, guidance and reset linear motion mechanism. The electromagnetic power-off brake is specific to the power-off electromagnetic brake for motors, which includes parts such as yokes, excitation coils, springs, brake discs, armatures, splines and spline sleeves, and screws for installation and locking.
