の制限ともなる。[Problem to be Solved by the Invention] However, since the braking torque of these brake motors is determined by the elastic force of the spring, if the performance of the spring varies, the braking torque also varies. Further, if the degree of expansion and contraction of the spring during braking changes due to the progress of the wear of the brake, the elastic force obtained from the spring may decrease, and the braking torque may decrease. Furthermore, it is necessary to finely balance the elastic force of the spring and the electromagnetic force that releases frictional braking against the elastic force, which is a design limitation.

The fixed braking unit is provided with electromagnetic means so that a magnetic pole appearing on the fixed braking surface has a single polarity, and supplies a motor driving current, and if the electromagnetic means is not energized, the rotor is fixed to the rotor by the motor driving current. Due to the magnetic attraction between the rotor and the rotor, the axial positions of the rotor and the rotation braking unit return to a state in which the rotation braking surface is separated from the fixed braking surface, the motor is operated, and power is supplied to the motor driving current. When the electromagnetic means is energized so as to stop and a magnetic pole opposite to the rotating braking surface appears on the fixed braking surface, the rotating braking unit is rotated together with the rotor by magnetic attraction between the permanent magnet body and the electromagnetic means. It is assumed that the rotary braking surface moves in the axial direction and the rotating braking surface is pressed against the fixed braking surface.

At this time, with the return of the rotor, the rotation braking unit also moves in the axial direction.
As a result, the braking is released, and the operation of the motor is restarted.

The frictional braking of the motor is performed by using the magnetic attraction force generated between the rotation braking unit and the motor in the axial direction of the rotation braking unit and by pressing the rotation braking surface and the fixed braking surface against each other. As described above, the braking torque does not vary due to the variation in the performance of the spring. Further, even when the rotational braking surface or the stationary braking surface is worn and the positional relationship between the rotational braking unit and the stationary braking unit at the time of pressing them is shifted, the magnetic attractive force between them does not decrease. Unlike a case where the spring is pressed by a spring, such a shift does not reduce the pressing force itself and does not cause a disadvantage that the friction braking torque is reduced.
