ROTARY ELECTRIC MACHINE

摘要

Obtain a rotary electric machine in which an insulation capability of bus-bar units is maintained in order to supply current to a coil of a stator of the rotary electric machine, and the whole stator can be downsized. In the arc-shaped bus-bar units which are laminated and arranged on a coil end of a stator of the rotary electric machine, a neutral-point bus-bar unit, which includes a neutral-point bus-bar is arranged at a midpoint of phase's bus-bar units, which include phase's bus bars.

1. A rotary electric machine comprising:
a stator, in which a coil is mounted on a stator core having an annular shape, which includes
a coil end which is protruded from an end surface of the stator so as to be formed,a coil terminal which is protruded, from an end portion of the coil end, in an coil end direction, andan arc-shaped bus-bar unit in which a connecting portion for connecting the coil terminal wraps a bus bar being protruded in an inner-outer diameter direction; wherein a neutral-point bus-bar unit, which includes a neutral-point bus bar, and phase's bus-bar units, which include phase's bus bars respectively connected to the coil of each phase, are laminated and arranged, in a protrusion direction of the coil terminal, in the bus-bar unit; and the neutral-point bus-bar unit is arranged between a plurality of the phase's bus-bar units.
