Magnetic powder clutch
The magnet is placed between the active part and the driven part. When the magnetic powder is not energized, it is in a loose state. When the magnetic powder is energized, the active part and the driven part rotate simultaneously. Advantages: torque can be adjusted by adjusting the current, allowing a large slip. Disadvantages: large slip temperature rise, relatively high price.
Differential electromagnetic clutch: when the clutch works, there must be a certain speed difference between the main and slave parts to have torque transmission. The torque depends on the strength of the magnetic field and the speed difference. The exciting current remains unchanged and the rotating speed decreases sharply with the increase of torque. The torque remains unchanged, the excitation current decreases, and the speed decreases more seriously.
Differential electromagnetic clutch due to the main, driven parts between any mechanical connection, no wear and consumption, no magnetic leakage, no impact, adjust the excitation current can change the speed, as a CVT use, this is its advantage. The main disadvantage of the clutch is that the eddy current in the rotor will generate heat, which is proportional to the speed difference. At low speed, the efficiency is very low. The ratio of rotational speed of the main shaft to that of the driven shaft, vertical =n2/n1.
Applicable to the mechanical transmission system of high frequency action, can be in the case of the operation of the active part, the driven part and the active part of the combination or separation.
When the active part and the driven part are separated, the active part rotates and the driven part is stationary. The active part and the driven part are jointed, and the active part takes the driven part to rotate.
Widely used in machine tools, packaging, printing, textile, light industry, and office equipment.
Electromagnetic clutch is commonly used in the environment temperature from 20 to 50 ℃, humidity is less than 85%, no explosion danger of medium, the coil voltage fluctuation is less than the rated voltage of plus or minus 5%.
