Abstract
A stator, a motor and a compressor are provided. The stator includes a stator iron core and a winding. The stator iron core includes: an annular yoke; multiple stator teeth, near ends of the stator teeth being fixedly adjacent to an inner surface of the yoke and projecting inward towards the center of the stator iron core along a radial direction of the yoke, remote ends of the stator teeth that face inward along the radial direction defining a center hole for accommodating a rotor, and the stator teeth being spaced from each other in a circumferential direction; and multiple stator slots, each stator slot being defined between two neighboring stator teeth. The winding is wound around the stator teeth and operable for generating a rotating magnetic field. The yoke has at least two cut edges at an outer periphery thereof, disposed asymmetrically relative to the center.
