Abstract
A radial stator includes a stator core, and the stator core includes a stator outer ring. M magnetic poles are arranged on an inner circumferential wall of the stator outer ring, and are evenly distributed along the inner circumferential wall of the stator outer ring. The M magnetic poles include M1 magnetic poles arranged along the inner circumferential wall of the stator outer ring and M2 magnetic poles arranged along the inner circumferential wall of the stator outer ring; M≥2, M1≥1, and M2≤1; the M1 magnetic poles and the M2 magnetic poles are arranged on two sides of the stator outer ring with respect to a radial direction thereof, respectively; each of the M1 magnetic poles is provided with a first winding; and each of the M2 magnetic poles is provided with a second winding; and a coil turn N1 of the first winding is greater or less than a coil turn N2 of the second winding.
