Servo Motor Electromagnetic Brake Definition, Characteristics And Principle

Servo motor electromagnetic brake operating principle: When there is current passing through the electromagnetic brake magnetic coil, the electromagnetic force pulls the brake pad and uses the brake pad to release the brake disc. At this time, the drive shaft is normally running or starting with the brake disc. When the current of the electromagnetic brake is cut off, the brake pad is separated from the brake disc, the friction torque is generated between the brake disc and the brake pad and the flange, and the drive shaft is quickly stopped.

Servo motor electromagnetic brake definition: electromagnetic brake is the excitation brake, generally consists of wire seat (magnetic coil), brake pads, guides and other components. It is a device that brakes, stops or holds a shaft or a rotating body, and an electromagnetic brake or electromagnetic brake is used to operate by electromagnetic force.

Features of Servo Motor Electromagnetic Brake: Electromagnetic brake has the characteristics of small size, light weight, compact structure, convenient operation, simple installation, high frequency operation, safe and reliable, durable, easy to maintain and easy to operate at a long distance. Electromagnetic brakes can be divided into energized and de-energized. Although DC24V voltage is used, the working principle is different, and the difference between them is clearer.

First, the working principle of the power-off servo motor electromagnetic brake:
The structure is that the brake pad is pressed by the coil spring, and the frictional force is used to generate the braking torque. When the excitation current is cut off, the spring pressure of the coil spring will cause the armature to press against the brake pad, and the brake will act. When the excitation disk tube is energized, the armature that presses the brake pad will wind the coil. Compressed, and attracted by the excitation magnet, the brake is liberated.

Second, the working principle of the energized servo motor electromagnetic brake:
When the current of the electromagnetic brake is cut off, the brake pad is separated from the brake disc, the friction torque is generated between the brake disc and the brake pad and the flange, and the drive shaft is quickly stopped. When the magnetic coil is used, the electromagnetic force pulls on the brake pad, and the brake pad is released by using the brake pad, and the drive shaft is normally operated or started with the brake disc.

The servo motor electromagnetic brake plays a role in transmitting power and controlling motion in the mechanical transmission system. It is an automatic actuator that is widely used in modern industry. Tailing brand electromagnetic brake has compact structure, fast response, simple operation and safe and reliable use.
Durable and easy to achieve long-distance control.
