The magnetic clutch is properly loaded

　　 Whether the magnetic powder clutch is properly loaded or not has a great influence on its durability. This kind of magnetic powder clutch can also be used under a continuous slip. Heat is produced by the slip of the magnetic powder clutch, and the temperature of the magnetic powder clutch is continuously increased, thus affecting its working ability. Under normal circumstances, the surface temperature of the magnetic clutch is controlled to be less than 100 degrees Celsius. When the loading capacity of the magnetic clutch is found to be downloaded, the magnetic powder should be replaced.

　　 When the magnetic clutch is started, since the magnetic powder clutch has a constant torque characteristic and the acceleration torque is always kept constant, no impact and vibration occur at the start-up. The magnetic powder clutch response time and speed, the excitation coil plus the voltage, and the excitation current from the excitation coil The coil time constant (T = L/R) determined by the resistance and inductance rises exponentially, and the response time from when the coil is energized to when the torque reaches the specified value is divided into the non-response time and the increase of the excitation current. The rise time, the non-response time is about a fraction of the time constant, the time constant of the magnetic clutch for power transmission is about 50 milliseconds minimum, and the special design can be less than 10 milliseconds. .
