Document Type and Number:
Japanese Patent JP6439622
Kind Code:
B2
Abstract:
A stator includes a stator core having slots, a stator coil comprised of three phase windings, phase busbars each electrically connecting a corresponding one of the phase windings to an inverter, and a neutral busbar star-connecting the phase windings to define a neutral point therebetween. In each of the slots of the stator core, there are arranged K in-slot portions of the phase windings of the stator coil in K layers so as to be radially aligned with each other, where K is an even number. The phase and neutral busbars are electrically connected with those in-slot portions of the phase windings of the stator coil which are arranged at the radially outermost layer or the radially innermost layer in the respective slots of the stator core so as to be circumferentially spaced from one another by M slot-pitches or more, where M is a slot multiplier number.
