Jctprint Machinery Co., Ltd
It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related winding and winding tension control. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation and the like. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.
Application:
It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related winding and winding tension control. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation and the like. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.
Working principle:
A.Magnetic powder brake is a new type of transmission component that uses magnetic powder as a medium to form a magnetic powder chain to transmit torque under energization. It is mainly composed of inner rotor, outer rotor, excitation coil and magnetic powder.
B.When the coil is not energized, the active rotor rotates. Due to the centrifugal force, the magnetic powder is clamped on the inner wall of the active rotor, and there is no contact between the magnetic powder and the driven rotor, and the active rotor idles.
C.After the DC power is turned on, an electromagnetic field is generated, and the magnetic powder of the working medium forms a magnetic powder chain under the action of the magnetic force line, and the inner rotor and the outer rotor are coupled to achieve the purpose of transmitting and braking torque.
Features:
A.The transmission torque is linear with the magnetizing current. The amount of torque can be controlled over a wide range. Under normal conditions, the magnetizing current is linear with the transmitted torque, in the range of 5%-100% of the rated torque.
B.The friction portion inevitably generates heat or even breaks while maintaining continuous sliding. However, the device has a complete cooling device, which does not generate a large amount of heat after a long time of operation and has a long service life.
1) High-precision torque control
2) Superior durability,long life
3) The stability of a fixed superior torque characteristics
4) Continuous operation of the use of sliding
5) Ink sleek,non-shock
6) Suitable for high-frequency operation
