Abstract: This cantilevered-shaft electric motor has no bearing on the load side, and since there also is no end bracket, which is present in ordinary electric motors, the internal stator and rotor are in an unprotected state in a bare state. The present invention provides a cantilevered-shaft electric motor that prevents damage to the stator and rotor during transport, causes handling properties during transport and during coupling to a load side to be favorable, and prevents contaminants from infiltrating. The cantilevered-shaft electric motor is provided with: a stator that is affixed at the inner diameter side of a housing; and a rotor that is rotatably borne disposed facing the inner peripheral side of the stator. The cantilevered-shaft electric motor has a structure such that the rotor is provided with a bearing at the reverse side from the load and the shaft at the load side is supported at an apparatus side. The cantilevered-shaft electric motor is characterized by being provided with a partition plate having a hole through which the rotary shaft penetrates at the load side of the rotor, the partition plate being provided with: a role as an affixing jig that supports the rotary shaft in a manner so that the rotor does not contact the stator during transport; and a role as a protective member that prevents the infiltration of contaminants from the outside.

Abstract: A cogging torque can be significantly reduced in a three-phase permanent magnet-type synchronous motor. In a three-phase permanent magnet-type synchronous motor where a fraction of 2N/3P is not an integer assuming the number of magnetic poles of a rotator is P and the number of slots of a stator is N, the stator includes a tooth facing a surface of a magnetic pole of the rotator via a void and a tooth width of the tooth in the circumferential direction is approximately ½ of a slot pitch of the stator. In a three-phase permanent magnet-type synchronous motor of an outer rotor type, the tooth of the stator has a radial cross section with an approximately uniform shape from a tooth tip portion to a tooth root portion or a radial cross section with a larger tooth root portion than a tooth tip portion to allow mounting a winding unit from the tooth tip portion. The winding unit is preliminarily wound by a coil.
