Document Type and Number:
Japanese Patent JP7085501
Kind Code:
B2
Abstract:
To suppress a heat generation of a conductor bar in a squirrel-cage induction motor.SOLUTION: A squirrel-cage induction motor comprises: a rotor shaft rotatably supported so as to be extended to an axial direction; a rotator iron core 100 attached to an outer side of a radial direction of the rotor shaft; a rotator which is arranged in a peripheral direction while having an interval each other, and has a plurality of conductive bars 50 penetrating the rotator iron core 100; a stator having a stator iron core arranged on the outer side of the radial direction of the rotator iron core 100 and a stator winding wire penetrating the stator iron core to the axial direction; and two bearings that rotatably support the rotor shaft on both sides of the axial direction of the rotor shaft while nipping the rotator iron core 100. In an outer side part 51 of the radial direction in the rotator iron core 100 in each of the plurality of conductive bars 50, a width of the peripheral direction is monotonically increased in accordance with an inner side of the radial direction.SELECTED DRAWING: Figure 3
