摘要： A stator for a multiple-phase rotary electric machine is provided with a stator core with slots and a coil formed of a plurality of windings for individual phases. Each winding has slot-accommodated portions accommodated in different slots, turn portions connecting the slot-accommodated portions outside of the slots in an axial direction, and a return portion that connects two of the turn portions and changes a winding direction of the winding at given slots. The turn portions include specific turn portions which are the same in a circumferential position as the turn portion connected to one of the return portion. The first and second windings are jointed to each other via a joined portion disposed in a specific slot among the slots.

摘要： An electric rotating machine includes a rotor, a stator in which a coil is so wound as to have an coil end, and a coolant supply pipe. The coolant supply pipe lies with a length thereof extending substantially parallel to an axis of rotation of the rotor and is disposed above the stator in a direction of gravitational force. The coolant supply pipe has a first and a second coolant outlet through which coolant is to be emitted to the coil end. The first and the second coolant outlets are so oriented as to direct streams of the coolant to a first area and a second area of the coil end which are different in location from each other. This enables the coolant to be emitted to almost the whole of the coil end even when the electric rotating machine is titled in a direction in which the rotor turns.

摘要： A sequentially joined-segment coil for a rotary electric machine such an electric motor is provided. The coil has an end portion which is made up of heads of conductor segments and projects from an end of a core. The heads of conductor segments have turns or bulges. The bulges are lapped over one another in various forms or shifted in location in an axis direction of the core, thereby permitting the core to be decreased in diameter, which provides for decreases in size and weight of the rotary electrical machine.

摘要： Provided is a multi-turn sequential segment joining stator coil capable of suppressing the differences in electromotive voltage between parallel circuits and of carrying a large current. Partial coils are accommodated in a plurality of continuous conductor accommodation positions of different slots. The partial coils accommodated in the same slot are separately connected in series to each other to produce parallel coils, and the produced parallel coils are connected in parallel with each other. This configuration enables the production of a sequential segment joining stator coil type electric rotating machine with a size-reduced head-side coil end.
