The brake motor shown in FIG. 4 has a simple structure, but since the brush 17 is constantly pressed against the brake plate 16, the brush 17 is always in contact with the brake plate 16 even when the motor is rotating. 17 and the brake plate 16 are significantly worn,
There is a problem that abrasion powder scatters inside the motor, and the frictional force changes so that the braking force is not constant.
