Micro magnetic powder clutch failure analysis
Micro magnetic powder clutch stuck usually occur in the following situations:
1 During the production process of the magnetic powder filled excess;
2 Because of long storage time in the transport process, resulting the magnetic powder between two groups of units scattered in one side, but not done before starting the excitation caused by stuck;
3 Using the magnetic powder is poor quality;
4 Because of low precision manufacturing, concentricity of the rotor is not enough, resulting in uneven output torque or stuck.
For the above, gives the following recommendations:
1 Option to purchase the quality assurance product
2 Before the formal operation or after moving device, you must do the evenly operation before the formal operation. So as to produce a smooth torque, evenly mode of operation is as follows:
After the state in the absence of excitation, the driving side as speed (1800rmp less) rotating about one minute, set the excitation current rated 1 / 4-1 / 5, on the one hand, turn around the driving side, on the other hand ,5 seconds open 10 seconds off, break intermittently excitation about 20 times.
