INSULATING METHOD FOR WINDING OF RANDOM WINDING INSULATED MOTOR, AND INSULATED WINDING

摘要

PURPOSE: To provide a random winding insulated motor which has extremely high reliability by preventing the deterioration of insulation without being accompanied by the increase of the number of components increase in size. ;CONSTITUTION: In the method of insulating the winding of a random winding insulated motor being driven by an inverter, it is insulated so that the partial discharge start voltage (CVD) between the turns of the insulated cable of the winding 1 of a motor may be higher than the surge voltage generated at combined operation of the inverter and the motor. Moreover, as the insulated cable of the winding 1 of the random winding insulated motor, an insulated cable being provided, outside of an enamel layer, with an insulating layer of glass or high polymer material excellent in radiation resistance is used.;COPYRIGHT: (C)1994,JPO&Japio
