Abstract
A coil assembly for a rotating electric machine is a stator coil for use in the stator of a motor or the like, which includes a coil plate composed of at least two coil plate elements respectively provided with an internal peripheral portion and an external peripheral portion and having predetermined wiring patterns formed by slits. The coil plate elements are bonded together at their internal peripheral portion and external peripheral portion while leaving the medial portion lying between the internal peripheral portion and the external peripheral portion spaced apart, so as to form the predetermined coil winding patterns.
Claims25
A coil assembly for use in a stator of a rotating electric machine, comprising:
- a coil plate having at least two coil plate elements,
- wherein each of the coil plate elements is formed of a plurality of metal sheets stacked and integrated, the coil plate elements respectively have an inner peripheral portion and an outer peripheral portion, as well as predetermined etched wiring patterns formed by etched slits, and are bonded together at the inner peripheral portion and the outer peripheral portion while spaced apart in a medial portion lying between the inner peripheral portion and the outer peripheral portion, so as to provide predetermined coil winding patterns, wherein the etched wiring patterns of the opposed different coil plate elements being bonded in a mutually reversed state.
A rotating electric machine comprising:
- a stator equipped with at lease one coil assembly;
- and
- a rotor,
- wherein the coil assembly is comprised of a coil plate having at least two coil plate elements, each formed of a plurality of metal sheets stacked and integrated, and the coil plate elements are each provided with an inner peripheral portion and an outer peripheral portion and have predetermined etched wiring patterns formed by etched slits and are bonded together at the inner peripheral portion and the outer peripheral portion while spaced apart in a medial portion lying between the inner peripheral portion and the outer peripheral portion, so as to provided predetermined coil winding patterns, wherein the etched wiring patterns of the opposed different coil plate elements being bonded in a mutually reversed state.
