The object is to provide an elevator hoist, which can be cooled down effectively by a little component when heat is generated. For achievement of the object, in the elevator hoist, a motor is configured by: a rotating body that is rotatably supported by a bearing on a spindle provided vertically at a central position of a rigid frame; a stator provided on the rigid frame; and a field magnet, which is provided on the rotating body, and which faces the stator. A heat pipe is provided inside the spindle, a portion of the heat pipe is projecting to the outside of the spindle, and heat radiation fins are provided on the projecting portion. Cooling fins are provided on the rotating body and arranged around the heat radiation fins. |
