Electro Magnetic Powder Brake/Clutch

Product Overview

Description

Electro-Magnetic Powder Brake/Clutch

Introduction of magnetic powder brake

The electro-magnetic powder brake/clutch is composed of active rotor(input shaft), driven rotor(output shaft) and Yoke with excitation coil. The three parts are assembled relative concentric and form a system which can rotate relatively. The annular gap between active rotor and driven rotor is full of alloy powder which has high magnetic conductivity.

 

Features of magnetic powder brake

• The transmission torque of magnetic powder brake has a linear relationship with the magnetizing current. The size of the torque can get controlled within large range. Under normal circumstance, the magnetizing current has a linear relationship with transitive torque within range of 5%-100% rated torque.
• The friction part will generate heat inevitably or even destroyed when it keep continuous sliding. But this device has a complete cooling set, it will not generate a lot of heat after long time running and it has a long service life.

 

Application of magnetic powder brake

Due to the features of the electro-magnetic powder clutch and brake, they have been widely used in paper making, printing, plastic items, rubber industry, textile industry, printing and dyeing,wire and cable, metallurgy industry and tension control of winding and winding in roll material processing industry.

 

About life of magnetic powder brake
The use of magnetic powder clutch/brake life lies in the life of the magnetic powder.In general, magnetic powder in the condition of not overloaded, its service life is 4500~7500 hours;But in some condition it can prolong service life many times, such as: reduce the electro magnetic powder clutch/brake torque, relative sliding speed and slip power to the rating of 50% 70%.That is to say, when the design, allowance enlarge some as much as possible.

 

About the torque of magnetic powder brake
Electro-Magnetic powder clutch/brake factory after use, the magnetic powder in the early stages of using break-in happens, torque will be slightly down, can be adjusted by electric current to compensate.
