The difference between energized electromagnetic brake and deenergized electromagnetic brake

The electromagnetic brake is divided into two types: energized electromagnetic brake and deenergized electromagnetic brake (electromagnetic deenergized brake or non excitation action brake). The energized electromagnetic brake must be powered on before it can operate, while the deenergized electromagnetic brake brakes after being powered off. Both use DC24V direct current. Many customers are not aware of the differences between them. Here, Hangzhou Mingte Transmission will introduce the differences between them.

The working principle of an electrified electromagnetic brake is: when the magnetic coil is used, the electromagnetic force attracts the brake pad, and the brake disc is released using the brake pad. At this time, the transmission shaft runs or starts normally with the brake disc. When the current of the electromagnetic brake is cut off, the brake pad will disengage from the brake disc, Friction torque will be produced between the brake disc and the brake pad and flange, and the transmission shaft will be used to stop quickly.

The working principle of a power off electromagnetic brake is: its structure is to use coil springs to press the brake pads, and use its friction force to generate braking torque. When the excitation coil is energized, the armature that presses against the brake pad compresses the coil coil, which is attracted by the excitation iron core, and the brake is in a released state. If 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.

The purpose, application fields, and characteristics of the powered electromagnetic brake and the powered electromagnetic brake are relatively similar, with small size, easy and simple installation, fast response speed, no no-load torque, environmental protection, and no noise. They are widely used in various mechanical rotation systems for starting, cutting, inching, positioning, variable speed, reversing, and other functions

In order to ensure the uninterrupted operation of the electromagnetic brake, it is necessary to regularly maintain and maintain it:

1. Frequently add lubricant to the movable part of the electromagnetic brake.

2. Regularly check the length of the armature stroke. Because during the operation of the brake, the travel length of the armature will increase due to wear on the moving surface. When the length of the armature stroke cannot reach the normal value, adjustments must be made to restore the small gap between the brake surface and the rotary table. If the stroke length of the armature increases above the normal value, it may greatly reduce the suction force.
