Classification: CPC F | IPC F

Claim 0:
1. An electromagnetic clutch, comprising:
a fixed component that includes a magnetic yoke that is provided thereon with multiple iron cores that each are provided thereon with a coil;
a driven component that includes an armature disc that is provided thereon with multiple magnets; and
an elastic component that is configured to keep the armature disc at a disengaged position from magnetic yoke,
wherein the armature disc and the magnetic yoke are disposed correspondingly, and the iron cores and the magnets are disposed correspondingly;
wherein, when the coil is energized in a forward direction, the iron core is configured to attract the magnet, and the armature disc overcomes an elastic force of the elastic component and moves to an engaged position with the magnetic yoke, so that the fixed component and the driven component are connected for transmission; and
wherein, when the coil is energized in a reverse direction, the iron core is configured to generate an electromagnetic force to reduce an attractive force of the magnet, the elastic force of the elastic component overcomes the attractive force of the magnet, and repels the armature disc to a disengaged position from the magnetic yoke.
