A solid-state electromagnetic rotor, including a plurality of salient pole pieces arranged around a supporting structure, wherein a first end of each salient pole piece is attached to the support structure and a second end of each salient pole piece points outward away from the sup-porting structure. The wires wound around each salient pole piece, wherein when the wires of the plurality of salient pole pieces are sequentially excited by an excitation circuit. The salient pole pieces are energized to provide a moving polar magnetic field in the form of distinct magnetic poles as desired to accomplish power generation.

A segmental stator, an electric motor have same and a household appliance are provided. The segmental stator includes: a plurality of main windings, a plurality of secondary windings, a plurality of winding needles and a wiring board. Each of the main winding and the secondary winding includes a core segment and a winding frame, and the winding frames of the main winding and secondary winding are wound with a main winding wire and a secondary winding wire respectively. The main windings include at least one first main winding separately wound with one main winding wire and at least two second main windings continuously wound with one main winding wire. The plurality of secondary windings include at least one or more of the following: at least one first secondary winding separately wound with one secondary winding wire and at least two second secondary windings continuously wound with one secondary winding wire.

An electric motor includes a main winding coupled to a first line terminal, and first and second boost windings coupled in series to the main winding. A high-speed lead wire is coupled to a first tap between the main winding and the first boost winding, a medium-speed lead wire is coupled to a second tap between the first boost winding and the second boost winding, and a low-speed lead wire is coupled to a third tap after the second boost winding. A start winding has a first end coupled to the first line terminal and a second end. A capacitor has a first end series-coupled to the second end of the start winding and a second end coupled to the second tap. A switch coupled to a second line terminal is configured to couple the second line terminal to one of the high, medium, and low-speed lead wires.
