Field of the Invention The present invention relates to a method in which a driving-side driven body and a driven-side rotating body are mechanically coupled to each other or braking is applied to the driving-side rotating body mainly by the attractive force of a permanent magnet. The present invention relates to a so-called non-excitation actuated electromagnetic clutch or brake in which the above is released by excitation by an excitation coil. For example, in the case of the non-excitation actuated electromagnetic brake, while the armature is attracted based on the magnetic flux of the permanent magnet to generate the braking force, the braking force is released by supplying a current to the exciting coil to permanently generate the magnetic flux. It is generated in the direction opposite to the direction of the magnetic flux of the magnet so as to cancel the braking force by the permanent magnet and make the braking torque zero.

に示すギヤ２を固定体と考えればよいのである。Next, the operation of the non-excitation actuated electromagnetic clutch shown in FIGS. 1A and 1B will be described with reference to FIG.
When no current is supplied to the exciting coil 7, the permanent magnet 8A generates a magnetic flux Φ 1 which flows out of the permanent magnet 8A, passes through the outer yoke 5, the armature 3, the inner yoke 6 and returns to the permanent magnet 8A. Since the electromagnetic attraction force based on this acts between the magnetic ends of the outer yoke 5 and the inner yoke 6 and the armature 3, the armature 3 is attracted to the outer yoke 5 and the inner yoke 6 side, and the armature 3 and the rotor 4 are attracted. Due to the contact friction with it, its armature 3, and thus the gear 2 of the driven body coupled thereto, is rotated. That is, when the energization of the exciting coil 7 is turned off, as shown in FIG. 2, the attraction force by the magnetic flux Φ 1 by the permanent magnet 8A overcomes the force of the leaf spring 3A, the armature 3 is attracted to the rotor 4, and the gear 2 Is designed to rotate. When a current is supplied to the exciting coil 7, the axial bundle Φ 2 generated by this current
Supplies a magnetic flux Φ 1 generated by the permanent magnet 8A in a direction to cancel the magnetic flux, and gradually increases the magnitude of this current, the electromagnetic attraction force between the magnetic poles of the outer yoke 5 and the inner yoke 6 and the armature 3 is increased. Gradually decreases,
Accordingly, the transmission torque also gradually decreases. That is, when the coil 7 is energized, as shown in FIG. 2, the magnetic flux Φ 2 from the coil 7 cancels the magnetic flux Φ 1 from the permanent magnet 8A, and the armature 3 is separated from the rotor 4 by the force of the leaf spring 3A. Position to create a gap. Although the above embodiment has been described with respect to the case where the present invention is applied to the clutch, the case where the present invention is applied to the brake will be described with reference to FIG.
The gear 2 shown in 1 may be considered as a fixed body.
