Jiaozuo brake

The brake manufacturer explains the working principle of electromagnetic brakes

The friction ring rotates with the brake drum, and the electromagnet is connected to the driving lever through a snap ring. At the beginning of braking, the controller sends a braking signal, and the electromagnet is energized to generate electromagnetic attraction, which is adsorbed on the friction ring. Due to the constraint of the electromagnet by the driving lever, it produces relative sliding with the friction ring, and the friction force acting on the electromagnet drives the driving lever connected to it to rotate around the pivot point. The driven end of the lever opens the two friction shoes of the brake and presses them against the brake drum, generating braking torque. At the end of braking, the electromagnet is powered off, and the suction and friction force disappear. Under the pulling force of the return spring, the friction shoe leaves the brake drum and releases the braking.
