PURPOSE: To prevent the collision sound between spline projections which occur at torque ripple by the gap between the spline projections.
CONSTITUTION: This motor provided with a brake is equipped with a magnet device 14 which forms a magnetic flux between a brake plate 5 and a fixed magnetic body such as a bracket 3, etc., and magnetic attraction in opposite direction from the direction of revolution is made to work on the brake plate 5. Moreover, the spline projection is provided with a slit, and the tip is opened with a wedge pin so as to bring adjacent spline projections into contact with each other and unit the hub 4 and the brake plate 5. Moreover, it will do to couple the hub 4 and the brake plate 5 with each other by a tension spring or a plate spring, and weld the space to one side to make it retain the hub and the brake plate.
