PROBLEM TO BE SOLVED: To provide a motor with reduced iron loss deterioration caused by shrink-fit from a viewpoint different from the conventional technology of reducing motor characteristics deterioration caused by shrink-fit by reducing compression stress.SOLUTION: The motor is formed by fixing by shrink-fitting a stator formed by laminating electromagnetic steel sheets to a housing. On an inner circumferential surface of the housing and/or an outer circumferential surface of the stator, an insulation coating layer, preferably an insulation coating layer of a film thickness of 0.5 to 30 μm composed of an insulating paint, is formed. |
