A pressure brake is a mechanical component that stops or decelerates moving parts in machinery. Commonly known as brakes or brakes. The Qiandai electromagnetic brake mainly consists of a brake frame, brake components, and control devices. Some electromagnetic brakes are also equipped with automatic adjustment devices for the clearance of brake components. In order to reduce braking torque and structural dimensions, electromagnetic brakes are usually installed on the high-speed shaft of equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment.

Pressure brakes have the advantages of simple structure, wide adaptability, low noise, and reliable braking, and are widely used in various mechanical transmission devices. They are an ideal actuator in industrial modernization. The automation of production technology requires ultra-thin power-off brakes (safety brakes) to meet the needs of various machinery such as robots and motors for different purposes with their excellent characteristics.
