A stator including, a stator core having a slot, a winding wire to be inserted into the slot; and an insulation sheet interposed between the slot and the winding wire and configured to electrically insulate an inner wall of the slot and the winding wire, wherein the insulation sheet includes an insulation paper, a first adhesive layer disposed on a front surface of the insulation paper facing the inner wall of the slot, and a second adhesive layer disposed on a back surface of the insulation paper facing the winding wire, a foaming adhesive to be thermally cured while foaming by heating is disposed on the first adhesive layer, and a non-foaming adhesive having lower viscosity than that of the foaming adhesive when unheated is disposed on the second adhesive layer.

A terminal block of a rotating electric machine includes a terminal block main body, a high-current electrical wire connecting section to which a high-current electrical wire of the rotating electric machine is connected, multiple neutral wire connecting sections to which neutral wires of the rotating electric machine are connected, and a bus bar that connects the neutral wire connecting sections to each other.

Terminal block of rotating electric machine

A rotor structure for a rotary electric machine in which an inner surface of a hollow rotor core and an outer surface of a shaft inserted into a hole of the rotor core are fitted together by mutual engagement between a projection and a recess to compose a rotor, the rotor structure including: a first retainer brought into contact with one end of the rotor core; and a second retainer brought into contact with a surface of the first retainer opposite to a surface in contact with the rotor core so as to fix the first retainer and the rotor core to the shaft, wherein a coefficient of static friction of a first sliding surface between the first retainer and the second retainer is smaller than any other sliding surface provided in the rotor.

The vibration and noise excited by the electromagnetic exciting force in the radial direction of an electric motor are suppressed. In an electric motor, a rotoris divided into four rotor pieces, andfor an axial length of 2L of one group of the rotor core, and for example, the four rotor pieces, andare ideally 0.29L, 0.71L, 0.71L, and 0.29L in axial length in the axial direction, and permanent magnetsof the rotor pieces, andare arranged in the circumferential direction so that the phase differences of the electrical angle are 0, &#x3c0;, 0, and &#x3c0;. Further, when an effect is obtained even if the ideal axial length is changed, the tolerance of the aforementioned axial length is &#xb1;0.1L.
