ROTARY ELECTRIC MACHINE

摘要

A rotary electric machine includes: a rotor core in which one or more permanent magnets are provided; and a stator core disposed radially opposite to the rotor core, a plurality of slots being provided in the stator core. Coils are disposed in the slots of the stator core. Further, the number q of slots per pole per phase, which is a value obtained by dividing the number Ns of the slots by the number P of poles of the permanent magnets and the number m of phases of a voltage induced in the coils, is a fraction having an odd denominator and an even numerator, and slot vectors which are electrical phases of the coils disposed in the slots are made to have unequal slot vector pitch angles in which pitches between the slots are unequal.

1. A rotary electric machine comprising:
a rotor core in which one or more permanent magnets are provided; a stator core disposed radially opposite to the rotor core, a plurality of slots being provided in the stator core; and coils disposed in the slots of the stator core, wherein the number q of slots per pole per phase, which is a value obtained by dividing the number Ns of the slots by the number P of poles of the permanent magnets and the number m of phases of a voltage induced in the coils, is a fraction having an odd denominator and an even numerator, and wherein slot vectors which are electrical phases of the coils disposed in the slots are configured such that slot vector pitch angles between the slot vectors have unequal pitches.
