To obtain a rotating electric machine capable of downsizing the rotating electric machine in an axial direction and in a radial direction. A first inner-peripheral-side terminal includes a first conductor-exposed portion and a second inner-peripheral-side terminal includes a second conductor-exposed portion opposed to the first conductor-exposed portion. An opposing portion being a portion, at which the first conductor-exposed portion and the second conductor-exposed portion are opposed to each other, extends in a radial direction, and at least a part of the opposing portion of the first conductor-exposed portion and the second conductor-exposed portion is arranged on an inner side in the radial direction compared to the first outer-peripheral-side terminal and the second outer-peripheral-side terminal.

A stator includes multiple coils. The coils include multiple outer coils arranged on the base side of teeth and multiple inner coils arranged on the tip side of the teeth. The outer coils and the inner coils are alternately arranged along the circumferential direction of a stator core. Each coil winding of the outer coils is formed in a non-fixed state, and each coil winding of inner coils is formed in a fixed state.

An electromagnetic induction pump includes a tubular internal inductor comprising a plurality of internal combs and of internal coils positioned between the teeth of the internal combs, the inside of the internal inductor forming a cavity; an internal tube positioned around the internal inductor; a pumping canal allowing the circulation of a fluid that is to be pumped, an external tube, the canal being between the internal tube and the external tube; a tubular external inductor positioned around the external tube and comprising a plurality of external combs and of external coils positioned between the teeth of the external combs; the electromagnetic pump further comprising a movement device for moving the internal combs, and able to vary the radial clearance between the internal combs and the internal tube and comprising a first part positioned inside the internal inductor and in connection with the internal combs so as to be able to move them radially, and a second part extending at least partially outside of the internal inductor and being connected to the first part in such a way as to control the first part.

Described is an electrical machine, including: a rotor having a magnetic flux source mounted thereto; a stator winding arrangement having a first set of electrical connections to provide a first output channel, and a second set of electrical connections to provide a second output channel, the first and second channels being electrically out of phase, wherein the stator winding arrangement is constructed from a plurality of winding portions which are connected in electrical series.

Annular portions of a first interphase insulting sheet have void portions. After a U-phase coil is inserted in wave winding, bridge portions are mounted to slots for an adjacent V-phase coil. The void portions are formed at positions corresponding to the bridge portions that are disposed between any two of coil ends. The annular portions are stretched to form a generally pentagon shape, which facilitates mounting of the V-phase coil. The void portions formed at positions that do not need insulation will not impair the insulating function of the first interphase insulating sheet. The void portions formed in alignment with extension of the bridge portions will not cause a drop in the strength of the annular portions.

The present description relates to an insulation cover of a resolver and a method for winding a coil of the insulation cover, which has a slack part formed on a coil by: a slit part formed on a body part so as to correspond to a terminal pin when winding the coil on the terminal pin of a terminal part formed at one side of the insulation cover; and a winding guide part protrudingly formed on a winder so as to correspond to the slit part such that the coil is inserted into or withdrawn from the slit part, relieves the tension, applied to the coil, by the slack part so as to minimize a break in the coil according to the thermal deformation or the deterioration of the coil, has a compact structure, is easily manufactured and reduces manufacturing costs.

An insertion groove is disposed on a tubular portion overlapping portion that is overlapped with an inner circumferential surface of a tubular portion of the stator core. Inter-coil insulating bodies that are disposed between a plurality of stator coils include a groove inserted portion. The groove inserted portion includes: a first inserted portion that can be inserted inside the insertion groove when the insulating film is in a bent and folded state; and a second inserted portion that is contiguous to the first inserted portion, a shape of a visible outline of a cross section of the second inserted portion being different than that of the first inserted portion. The second inserted portion generates a stronger elastic force of recovery than the first inserted portion when the groove inserted portion is inserted into the insertion groove.

A stator configured with an annular stator core, and a plurality of coils mounted on the stator core. The bus bar portion being connected to the terminal portion of a different one of the coils of the same phase. The coil is a multi-layer coil that is formed by winding the conductor in a plurality of layers in an inside-outside direction of loops in the winding portion, and that includes on inner and outer peripheral sides of a coil end portion of the coil a plurality of lane change portions formed by the conductor. The bus bar portion is embedded in a clearance between the lane change portions of the coil of a different phase placed between the coils of the same phase which are connected to each other.
