A stator of a dynamo-electric machine suppresses short-circuiting attributable to joint portions so as to provide good insulating properties. In a front coil-end group, a turn portion of a first conductor segment and a joint portion of end portions of a second conductor segment are adjacently aligned in a single row in a radial direction, being arrayed in two rows in a circumferential direction. In a rear coil-end group, a joint portion of the end portions of the first conductor segment and the turn portions of the second conductor segment are adjacently arranged in a single row in the radial direction, being arrayed in two rows in the circumferential direction.

A field replaceable air-gap cartridge armature device for use in rotating electric machines is presented. The cartridge armature includes a plurality of bent-shaped air-gap windings rigidly arranged in a circular fashion to form an inner rim, an outer rim and an active section. The inner and outer rims are formed by end turn sections that are bent toward and away, respectively, from the center of the cartridge device. The windings may be generally arranged into a Z-shaped cross-section that is embedded in a fiber reinforced epoxy resin matrix to provide a rigid structure for transferring torque from the air-gap windings to a stator. Countersunk fasteners are used to easily attach and remove the cartridge armature from a rotating electric machine. The cartridge armature can be configured as a three phase, Y-connected armature circuit, and provides electrically insulated, substantially vacuum tight terminal penetration of a rotating electric machine for electrical feed-throughs.

A stator assembly for an electric machine, for example, for an automotive alternator. The stator assembly includes a metal core with windings installed into slots of the core. A pair of conductors of a continuous form is used for each phase of the machine. The windings are interlaced to alternate between radially inner and outer positions in each adjacent winding slot of the stator core.

A field part of an electronically switched two-phase reluctance machine includes a plurality of individually wound U-shaped yoke assemblies. Each assembly includes winding carrying U-shaped magnets attached to a non-magnetic carrier frame. Each yoke assembly has winding connections which are interconnected by a form-defined, axially mountable electric conductor compound. Power conducting electric components are electrically connected to the electric connector compound as well.

An alternator includes a rotor and a stator having a stator core surrounding the rotor, and a polyphase stator winding installed in the stator core, the stator core being provided with an abutting portion extending axially making the stator core into an annular shape by abutting end portions of the stator core, the polyphase stator winding comprising a number of winding portions in which long strands of wire are wound so as to alternately occupy an inner layer and an outer layer in a slot depth direction within slots at intervals of a predetermined number of slots, the strands of wire folding back outside the slots at axial end surfaces of the stator core, and an insulating member being interposed between the stator core and straight portions of the strands of wire in the winding.

In a stator for a dynamo-electric machine, a winding includes a conductor having a rectangular cross-sectional shape in a direction perpendicular to an axial direction, an overall shape of the conductor being a crank shape when flattened out, and the conductor includes straight portions laminated within slots, and bridge portions connecting the straight portions to each other, the bridge portions protruding from both end surfaces of the stator core in the axial direction.

A 4/6 pole PSC motor having main and auxiliary winding configurations. Common windings are energized in both a 4-pole configuration and energized in a 6-pole configuration for both the main and the auxiliary winding configurations. An additional winding is energized in the 4-pole configuration only. As a result, the air-gap flux level of the 4-pole configuration can be varied substantially independent of the air-gap flux level of the 6-pole configuration by varying the configuration of the additional winding.

A winding method comprises winding a single conducting wire around a predetermined number of pegs in sequence to thereby form a stator coil assembly having even coils and two ends. The winding direction of each coil is opposite to a coil adjacent thereto. The stator coil assembly having even coils is mounted to a casing of a D.C. motor with the coils located corresponding to a permanent magnet of a rotor. The rotor having the permanent magnet is driven to turn by magnetic forces created as a result of energizing the coils.

The delay locked operation is intermittently conducted only when a command or signal is supplied from outside, and a delay time changed in the delay locked operation is retained thereafter in the period that the command or signal is not supplied. Also, the dummy pattern used in conducting the phase comparison between internal clock ICK and external clock ECK is obtained through the output circuit that has the same characteristics as the output circuit from which data are actually output. Therefore, the accurate coincidence between internal clock ICK and external clock ECK can be obtained regardless of the parasitic inductive and capacitive loads that are influenced depending on the characteristic of package and the mounting conditions. Thereby, the delay locked operation can be always conducted accurately.

A stator assembly comprises upper and lower pole plates or silicon steel sheets each having a plurality of radial poles. Each radial pole includes a magnetic pole face extending along a direction parallel to a longitudinal direction. The magnetic pole faces of each upper pole plate, each lower pole plate, or each silicon steel sheet may be of the same or different length. Alternatively, the magnetic pole faces may be overlapped with each other or not overlapped with each other. The overall magnetic pole face formed by the magnetic pole faces may be so arranged to represent a step-like structure or an inclined side.
