Abstract

An electromagnetic clutch is provide that includes a fixed component, a driven component and an elastic component. The fixed component includes a magnetic yoke provided thereon with multiple iron cores, and each iron core is provided thereon with a coil. The driven component includes an armature disc provided thereon with multiple magnets. The armature disc and the magnetic yoke are disposed correspondingly, and the iron cores and the magnets are disposed correspondingly. The elastic component is used to keep the armature disc at a disengaged position from magnetic yoke. When the coil is energized in a forward direction, the iron core attracts the magnet and when the coil is energized in a reverse direction, the iron core generates an electromagnetic force to reduce an attractive force of the magnet.
