Abstract
A stator device which prevents the formation of varnish accumulations on jumper wires, thereby preventing jumper wire breakage due to temperature variations. A gap is created between the jumper wire and the stud located on the stator body. When varnish is applied to the stud and the jumper wires, excess varnish flows through the gap and pools underneath. Moreover, when there is a significant accumulation of varnish in the gap, the varnish will flow off from the edge of the stator body.
Claims20
A stator device comprising a stator body having at least a pair of magnetic protuberances for supporting a wound wire, at least one stud disposed between the at least a pair of magnetic protuberances, a jumper wire extending behind the at least one stud and connecting the at least a pair of magnetic protuberances, and an abutment extending from the at least one stud to support the jumper wire and form a gap between the jumper wire and the stud to permit an applied varnish to flow out through the gap.
In a stator device having a stator body provided with a plurality of magnetic protuberances for supporting a wound wire, studs disposed between the plurality of magnetic protuberances and jumper wires that connect at least two adjacent magnetic protuberances and extend behind the studs, a method of winding a wire and applying a varnish to the wound wire comprising the steps of winding the wire around the magnetic protuberances, spacing the jumper wires from at least one of the studs and the stator body and applying a varnish to the wire such that excess varnish applied to the jumper wires flows through the spacing formed between the jumper wires and at least one of the studs and the stator body.
A stator device having a stator body provided with magnetic poles and windings connecting the magnetic poles, studs for supporting a connecting portion of the windings extending between the magnetic poles, and at least one of the studs including an abutment for spacing the connecting portion of the winding from at least one of the studs and the stator body.
In a stator device having a stator body having at least a pair of magnet protuberances for supporting a wound wire, at least one stud disposed between the at least a pair of magnet protuberances, a jumper wire extending behind the at least one stud and connecting the at least a pair of magnetic protuberances, the at least one stud comprising an abutment member extending from a wall of the at least one stud facing the jumper wire for supporting the jumper wire such that a gap is formed between the stud wall and the stator body.
