The disclosure relates to magnetic resonance imaging triggered by a prospective acquisition correction sequence. The technique comprises determining repetition time and an acquisition window time of a single-shot fast spin echo sequence; determining the maximum imaging layer number N in each physiological movement cycle on the basis of the acquisition window time and the repetition time, where N is a positive integer greater than or equal to 2; and enabling the single-shot fast spin echo sequence to obtain M layers of imaging data within at least one acquisition window time when the prospective acquisition correction sequence generates a trigger signal, where M is a positive integer greater than or equal to 2 and less than or equal to N. According to the present disclosure, a plurality of layers of imaging data are obtained within a single acquisition window time, thereby increasing a scanning speed and shortening imaging time.

An embodiment provides a stator core including a plurality of first single teeth, a plurality of second single teeth and coils. The teeth are I-shaped and each have a long side, a short side, a connection portion and a wire-accommodating slot located on the sides of the connection portion. The coils are wound around the connection portions and accommodated in the wire-accommodating slots. The stator core is an annular element formed by splicing first single teeth and second single teeth in sequence in a staggered manner into a circle, and winding modes of the coils on the first single teeth and the second single teeth are different, so that the contour of the coils located on the outer side of the wire-accommodating slots of the first single teeth is different from the contour of the coils located on the outer side of the wire-accommodating slots of the second single teeth.
