Is The Load Of The Magnetic Powder Clutch Appropriate?

Whether the load of the magnetic powder clutch is suitable for its durability has a great influence. The magnetic powder clutch can also be used under continuous slip, and the heat generated by the slip of the magnetic powder clutch causes the temperature of the magnetic powder clutch to rise continuously, thereby affecting its working ability. Normally, the surface temperature of the magnetic powder clutch is controlled to be below 100 degrees Celsius. When the magnetic powder clutch load capacity is found to be downloaded, the magnetic powder should be replaced.

When the magnetic powder clutch is started, the magnetic powder clutch has constant torque characteristics, so the acceleration torque is always kept constant. Therefore, no shock and vibration occur when starting, the magnetic powder clutch response time and speed, the excitation coil is applied with voltage, and the excitation current is generated by the excitation coil. The coil time constant (T=L/R) determined by the resistance and inductance rises exponentially, and the response time from the start of energization of the coil until the torque reaches a predetermined value can be divided into non-response time and the same tendency to increase the excitation current. The rise time, the non-response time is about a fraction of the time constant, the time constant of the magnetic powder clutch for power transmission is about 50 milliseconds, and the special design can be less than 10 milliseconds. The same phenomenon occurs when disconnected. .
