Abstract

PURPOSE:To prevent a wedge insulating paper from moving due to vibration by projecting the wedge insulating paper at bore side slot from the end face of stator core upto the coil end and then bundling the wedge insulating paper, together with the coil end, by means of a bundling paper. CONSTITUTION:Wedge insulating papers 21-28, fit respectively in slots 12-19, are projected from a stator substantially upto a coil end formed by stator windings 11-14 and stator windings 15-18. Consequently, when the wedge insulating papers 21-28 are inserted unto the slots, insertion is completed when the leading end of an inserter reaches the height of the coil end. Subsequently, the wedge insulating papers 21-28 are bundled together with the coil end by means of bundling threads 41-47 at the time of shaping of coil end. Since the wedge insulating papers are secured to the coil end by means of the bundling threads, the wedge insulating papers are prevented from being shifted or removed due to vibration at the time of starting or driving of motor.

Numerals 30 to 37 are slot insulating papers inserted in the slots 12 to 19 and are 3 to 3 from the end surface of the stator core.
It is inserted by protruding about 5 mm. Since the slot insulating paper is inserted into the slot before inserting the stator winding, the slot insulating paper inserting jig does not damage the stator winding. Therefore, it suffices that the slot insulating paper has a length capable of ensuring the insulation of the slot, and the insulation of the slot is maintained by the protrusion of about 3 to 5 mm.
