<p>PROBLEM TO BE SOLVED: To provide a motor having a highly reliable electromagnetic brake, which can be formed thinner with higher fitting accuracy and higher yield, can prevent adverse effect of leakage magnetic flux of electro-magnetic brake for the motor, and can remarkably extend the operation life of the electromagnetic brake. SOLUTION: The electromagnetic brake is configured with an armature 12 which can be moved in the axial direction with an attraction through feeding electrical power to the electromagnetic coil 11 and an reaction of a spring, a hub 13 fixed to a rotor rotating shaft 15c, and a lining 14 located between the armature 12 and hub 13. A rotating part of the electromagnetic brake accommodates a projected part 13a of the hub 13 into a recessed part 15d provided at the center of the rotor yoke 15b in the electro-magnetic brake side only with the hub 13 provided with the fixed lining 14 in order to fix the projected part 13a to the rotor rotating shaft 15c with a screw 13b.</p> |
