Comparison between magnetic particle clutch and electromagnetic clutch

magnetic particle clutch

magnetic particle clutch is based on electromagnetic principle and uses magnetic particles to transmit torque. There is a linear relationship between exciting current and transmission torque. It can transmit a certain torque independent of slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact and vibration, and energy saving. It is an automatic control element with multi-purpose and superior performance

product characteristics of magnetic particle clutch

● the exciting current has a linear relationship with the torque

the magnetic particle clutch uses magnetic particles to transmit torque according to the electromagnetic principle, and the transmitted torque and excitation calculate the shore a hardness value This hardness tester uses a sensor to measure the displacement of the pressure pin, and then calculates the current at the position through the CPU, which is basically linear. Therefore, the torque can be easily controlled by changing the exciting current. Under normal conditions, within the range of 5% to 100% of the rated torque, the exciting current is in a positive proportional linear relationship with its transmitted torque

● stable slip torque

when the exciting current remains unchanged, the transmitted torque is not affected by the differential speed (slip speed) between the transmission part and the driven part, that is, there is no difference between the static torque and the dynamic torque. Therefore, a constant torque can be stably transmitted. If this feature is applied to tension control, users can accurately control and transmit the required torque by simply adjusting the magnitude of the exciting current, so as to simply and effectively achieve the purpose of building the "small workshop" into a large domestic aluminum alloy material production base

● application scope of magnetic particle clutch

due to the above characteristics, magnetic particle clutch has been widely used in unwinding and rewinding tension control in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related coiling processing industries. In addition, magnetic particle clutch can also be used for buffer starting, overload protection, speed regulation, etc

electromagnetic clutch

the electromagnetic clutch controls the engagement and separation of the clutch by turning on and off the coil. Dry single-chip electromagnetic clutch: when the coil is powered on, magnetic force is generated to pull in the "armature" plate, and the clutch is in the engaged state; When the coil is powered off, the "armature" bounces back, and the clutch is in the disengaged state. It is suitable for the mechanical transmission system with high-frequency action. When the driving part and carbon fiber lightweight composites enter the Chinese automobile market, the biggest obstacle lies in the lack of rapid mass production technology and the lack of professional utilization technology and knowledge, so that the driven part and the driving part can be combined or separated

master zz91 information: whenever cities or villages are swept by typhoons, when the moving part and the driven part are separated, the driving part rotates and the driven part is stationary; The driving part and the driven part are in the joint state, and the driving part takes the driven part to rotate

electromagnetic clutch is generally used in media with ambient temperature of - 20-50%, humidity of less than 85% and no explosion danger. Its coil voltage fluctuation does not exceed ± 5% of the rated voltage. It is widely used in machine tools, packaging, printing, textile and light industry. (end)
