Abstract
A rotary electric machine according to the present disclosure provides a rotary electric machine including: a rotor; and a concentrated winding stator arranged coaxially to the rotor, in which the number of teeth of the concentrated winding stator is set to be a value where an integer which is multiple of 3 between adjacent prime numbers in a prime number sequence is multiplied by 2 and the number of poles of the rotor is set to be a value where any prime number between the adjacent prime numbers is multiplied by 2.

A rotary electric machine comprising:
- a rotor;
- and
- a concentrated winding stator arranged coaxially to the rotor, wherein
- the number of teeth of the concentrated winding stator is set to be a value multiplied by 2, the value being an integer that is a multiple of 3, and the integer being between adjacent prime numbers in a prime number sequence,
- the number of poles of the rotor is set to be a value equal to one of the adjacent prime numbers multiplied by 2,
- the number of teeth is a multiple of 12 and the number of poles is defined as 12k±2, where k is 7 or 17, the number of poles being at least 80, and
- a short pitch factor of the concentrated winding stator is in a range of 0.998 to 0.999.
