摘要： PURPOSE:To prevent the winding of a rotary electric machine from deforming due to thermal expansion of the winding and improve the wear resistance and thermal deterioration resistance of insulating collar by providing a small slide layer having low frictional resistance between the lower surface of the heat of a magnetic pole and the insulating collar. CONSTITUTION:There is interposed a slide layer 14 fabricated by hardening, for example, a sheet blank 12 such as asbestos of glass using adhesive and coating low frictional material 13 such as ethylene tetrafluoride resin or the like thereon between the lower surface of a magnetic pole piece 2 of the end of a salinet-pole field 1 and an insulating collar 3. Thus, even if winding 6 is thermally expanded, the collar 3 is slidded accordingly to thereby eliminate the thermal deformation of the winding 6. Further, it can prevent the collar 3 from deteriorating due to contact of the pole piece 2 directly with the collar 3.
