Particle Brakes

Working Principle:

The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. It has the characteristics that the excitation current and the transmission torque are basically linear. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. It is a multi-purpose, high-performance automatic control component. It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other unwinding and winding tension control in the coiling and processing industry. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.
 

A.Use
1. Buffer start and stop: The start and stop of the buffer are achieved by the smoothing characteristics and the constant torque characteristics at the time of connection.
2, continuous sliding, tension control
3, torque limiter
4, high-speed response
5, power absorption
6, positioning stop
7, for analog load
B.Characteristics
2, can achieve continuous sliding operation.
3, you can get a stable torque.
4, no sounds. The slip phenomenon of the action surface occurs in the friction mode, but it does not occur here, and the connection sound is not emitted, so the operation is quite quiet.
5. The heat capacity is very large. Thanks to the use of magnetic powder with excellent heat resistance and the use of an ideal cooling method, it can be used with peace of mind even in the case of too severe continuous sliding operation.
6, can achieve smooth continuous and driving state. Since the static friction coefficient and the dynamic friction coefficient are almost the same, there is no oscillation when fully connected, and the load can be added and subtracted.

Application examples
Magnetic powder brakes are widely used, and they are roughly classified into the following types:
Startup, Brake Control This application includes normal start (clutch) and brake (brake). Since the motor is started at no load, the maximum torque of the motor can be fully utilized when starting the load. Therefore, even if the load GD2 or the starting resistance is large, it can be easily started up, and the starting process is smooth without causing a significant impact. In addition, since the motor is completely idling, it is of great benefit to improve the working conditions of the motor and prolong its service life. In addition, according to the torque characteristics, it is only necessary to adjust the excitation current to achieve the purpose of controlling the start and braking time, or changing the start and brake process curves.

Practical applications include large transmission equipment, walking cranes, large blowers, axial fans, air compressors, cement kilns, paper machines, rotary impact machines, rolling, rolling machines, wire drawing machines, large textiles, printing and dyeing, printing. Machinery, as well as the inching and operation of various industrial machinery.
