ACTION:

 This clutch is a magnetic close type which engages on when coil is excited. The field is excited then and magnetizes rotor to engage for facing with friction force. When the current is interrupted, magnetizing is disapeared and armature returns back quickly with release spring and then clutch is rereased. Clutch torque can be easely controlled by adjusting current.


MERITS:
1Strong structure.
2.Easy maintenance and installation.
3.Quick response.
4.Large heat dissipation.
5.Small residual torque.
