Abstract

PURPOSE:To obtain the armature of the rotary electric machine of low magnetic reluctance, by adjusting the section of an armature winding which is inserted into a slot, to the shape of the slot, to form the section in a square shape. CONSTITUTION:An armature winding 1 consists of inserted sections 101-104 which are inserted into a slot, end sections 105 connected to the inserted sections 101-104, and terminal sections 106 connected to commutators. The cross sections of the inserted sections 101-104 which are inserted into the slot are adjusted to the shape of the slot, to be formed in square shapes. The cross sections of the terminal sections 106 connected to the end sections 105 and the commutators 9 are formed in circular shapes. As the result, the magnetic reluctance of the armature and the internal resistance of the armature winding are reduced, and the components can be miniaturized.

According to the present invention, since the portion of the armature winding that is inserted into the slot has a rectangular shape in accordance with the shape of the slot, it is possible to obtain an armature for a rotating electric machine with low magnetic resistance, and also Even if the end parts overlap in multiple layers, since the end parts have a circular shape, the bulge is smaller than that of a rectangular shape, so the end parts do not become long, and therefore the internal resistance of the armature winding can be reduced. At the same time, it has the advantage of being able to downsize the armature of a rotating electric machine.
