Discussion on the Application of Electromagnetic Power Loss Brake in Motor
Release time:
2021-10-08
Electromagnetic power-off brake is an additional device commonly used in motors, and there are two types of power-on brake and power-off brake. The positioning of the energized braking method is fast and accurate. For automated intelligent control equipment that requires precise positioning. There are some limitations in the application. Packaging and printing, textile, automated production lines and other mechanical transmission systems with positioning and braking requirements are commonly used. In addition to the advantages of flexible control and fast braking speed, power-off braking means that the equipment can also brake safely when the power supply is accidentally out of control. Ensure the safety of personnel and facilities.

Electromagnetic power-off brakeStructural advantages and characteristics
●The structure is compact, the axial size of the power-off brake is small, but the braking torque is large enough.
●The fast response power-loss brake uses a spring energy storage device to form a braking torque, and the spring and arrow reset time is the braking response time.
●The long-life brake uses a new type of friction material, which determines the long-life performance.
Electromagnetic power-off brakeThe working principle
Electromagnetic power-off brakeIt is mainly composed of a yoke with a coil, an armature, a coupling plate, a spring, a friction disc, and a gear sleeve. The spring is mounted in the yoke, and the armature is movable in the axial direction. The yoke is fixed on the base by mounting screws to adjust the gap. After reaching the specified value, the gear sleeve is connected with the transmission shaft through a key, and the external teeth of the gear sleeve mesh with the internal teeth of the friction disc.
When the coil is de-energized, under the action of the spring force, the friction disc and the armature, the base (or coupling plate) produce friction, and the transmission shaft is braked by the gear sleeve. When the coil is energized, under the action of electromagnetic force, the armature is attracted to the yoke, thereby releasing the friction disc and releasing the brake.
Electromagnetic power-off brakeWorking conditions
●The ambient air relative humidity is not greater85%（20±5 ℃）
●There is no corrosive metal and gas or dust that damage the insulation in the surrounding medium.
●Use around the brakeBClass insulation, voltage fluctuation not exceeding rated voltage5%and-15%. Its working method is the installation control requirement of continuous working system.
●When installing, ensure the matching accuracy of the drive shaft and the brake.
●Electromagnetic power-off brakeBefore installation, it must be cleaned, and there must be no oil and dust on the friction surface and inside the brake.
●The gear sleeve must be fixed axially.

The working principle of electromagnetic brake
2022-10-09
The electromagnetic brake is a connector that transmits torque from the active side to the passive side. Any combination of cutting or braking can be required. The electromagnetic brake has compact structure, simple operation, sensitive response and easy to realize remote control.
The company has a product research and development department composed of experts, senior engineers and other professional and technical personnel. It is engaged in research and development and has perfect research and development test equipment. At present, the products reach more than 100 series of nearly 1,000 specifications, and the force distance ranges from 0.1N. m ~ 250000N.m. The company has been rated as a high-tech enterprise by the state for more than ten consecutive years, and a number of R & D projects have been established locally and have received municipal financial support.
