PURPOSE:To simplify the assembling by bringing the end face of the inner ring of a rolling bearing and the end face of a rotor for detection of salient pole position into close contact with each other in axial direction, and also, bring the end face of the outer ring of the rolling bearing into close contact with a bearing supporting member. CONSTITUTION:The end face 5f of the inner ring 5b of a rolling bearing 5B is set to abut on the step 4B of the rotary shaft 4 on the side of a bearing supporting member 1B, and the outer ring 5b of the rolling bearing 5B is set in said bearing supporting member 1B. This is of such constitution that the end face 5g of the outer ring 5c of the rolling bearing 5A is set to contact closely with the end face 1c of the bearing housing of the bearing supporting member 1A, so it is fastened and fixed in the axial direction with a pressing cover 1b. The end face 5e of the inner ring of the rolling bearing 5A and the end face 3c of the rotor 3 for detection of the salient pole position are in close contact with each other in axial direction, and also the end face 5g of the outer ring of the rolling bearing 5A and the end face 1c of the bearing housing of said bearing supporting member 1A are in close contact with each other in axial direction, and a salient pole position indicator 3a and an element 2 for detection of the salient position are kept at a specified interval. |
