Characteristics and Principle Of Fast Power-off Electromagnetic Brake
Release Date:21/11/2019
Fast loss of electricity electromagnetic brake has the advantages of simple structure, low noise and reliable braking. An ideal performance element in industrial modernization. Loss of power brake with its excellent characteristics to meet the different USES of robots, motors and other different mechanical needs. The main features are as follows:
1, Compact structure, loss of power brake axial scale is small, but the brake torque is large enough.
2, Response is agile: the loss of power brake is selected to constitute the brake torque, thin spring reset moment is the brake sound.
3, Should be long life: the loss of power brake selection of new resistance data.
The lost power electromagnetic brake is composed of magnetic yoke, excitation coil, tension spring, brake disc, armature, spline sleeve, dart nail, etc. The manual release type brake is extended at the rear end of the flange (or motor) of the device. The drive shaft is connected with the spline sleeve and the brake disc. 's excitation coil through additional voltage (DC brake, electromagnetic force and the armature, the armature and the brake disc from (free) at this time the shaft with a brake disc normal operation or start, when the power transmission system or respectively, brake power together, at the moment spring pressure on the street, the iron, forced the brake disc and armature and collide between flange moment, make the drive shaft quickly shut down. Brake cooling environment is poor, the drive shaft is long time continuous operation, if the conditions allow, can be in the brake operation, adhere to the voltage conversion for 70%-80% of the additional voltage, in order to reduce the heat.
