Reference numeral 1 denotes a support member, which includes a hollow shaft portion 1a and a disk-shaped fixing portion 1b extending radially from one end of the shaft portion 1a, and is fixed to an elevator hoistway or the like. The rotor 2 is configured by providing a permanent magnet 4 on the outer periphery of the rotor core 3, and the rotor 2 is rotatably supported by the shaft portion 1 a of the support member 1 through a bearing 5. A sheave 6 is fitted and fixed to the protruding small-diameter portion 3a formed on one end of the rotor core 3, and a rope groove 6a is formed on the outer periphery of the sheave 6, and the rope groove 6a passes through the elevator hoistway. A rope 7 for suspending the elevator car is wound. Further, a brake drum 8 having a diameter larger than that of the sheave 6 is formed at an end portion and an outer peripheral portion of the rotor core 3 on the small diameter portion 3 a side. The outer diameter of the brake drum 8 is larger than that of the rotor 2 and the outer diameter of the support member 1. Smaller than. On the other hand, the stator 11 includes a stator core 9 and a stator winding 10, and the stator core 9 is integrally attached to the support member 1 with mounting bolts 12.
