摘要： A device can prevent a failure in the actuation of a braking mechanism, which is caused by adhesion of adhesive substances. The device includes a heating part for heating the braking mechanism, a heat controller for controlling a heating operation of the heating part, a brake controller for actuating the braking mechanism when the heat controller stops the heating operation, and the temperature of the braking mechanism decreases, an actuation delay measuring part for measuring an actuation delay of the braking mechanism when the brake controller actuates the braking mechanism, and a comparison part for comparing the actuation delay measured by the actuation delay measuring part with a reference value of the actuation delay of the braking mechanism.

摘要： A connector for power or braking attached to an electric motor is based on resin molding around a ground pin and a power supply pin. In this connector, an electrical junction between the ground pin and the body of the electric motor or of a brake is disposed in a predetermined position on the inner peripheral side of a sealing portion which seals the interior of the brake or electric motor body from the air.

摘要： In a stator of an electric motor having a resin molding portion formed in an inner circumferential portion and an outer circumferential portion by means of injection molding, a partition member for partitioning the inner circumferential portion and the outer circumferential portion of the stator is provided in an axial end portion of the stator. Resin injected from the axial end portion flows in a bifurcated passage into the inner circumferential portion and the outer circumferential portion. The partition member may be provided with a resin passage which allows resin to flow from the axial end portion of the stator to the outer circumferential portion.
