PROBLEM TO BE SOLVED: To solve the problem in which further cooling of a motor may be required in a hoisting machine for elevators.SOLUTION: A hoisting machine includes a rotor, and a stator. The rotor is rotatably supported by a bearing, and rotates a sheave around which a rope is wound. The stator surrounds the outer peripheral side of the rotor and rotates the rotor by electro-magnetic force. The hoisting machine is provided with a liquid passage in which liquid for cooling the stator flows. |
