AC Motor

Abstract

The motor includes a rotor including N-pole magnets and S-pole magnets located alternately along a circumferential direction of said AC motor, a stator core including a plurality of partial cores arranged coaxially along an axial direction of said AC motor each of said partial cores including a plurality of stator poles located along said circumferential direction so as to be on the same circumference, and a plurality of loop-like windings each of which extends in said circumferential direction while passing through, in said axial direction, interpole spaces between each two adjacent stator poles in said circumferential direction. The a phase angle difference between each adjacent two of said stator poles in said circumferential direction of the same one of said partial cores is set at a value smaller than 360 degrees for each of said partial cores.
