Segmental stator, electric motor having the same, and household appliance

An electric motor, comprising:

• a rotor assembly comprising a rotor shaft and a rotor core disposed at the rotor shaft;
• and
• a segmental stator comprising:
• a plurality of main windings and a plurality of secondary windings, wherein:
• each of the main winding and the secondary winding comprises a core segment and a winding frame disposed to the core segment, and the core segments of the main windings and the core segments of the secondary windings are staggered and connected with one another in a circumferential direction to form an annular shape;
• the plurality of main windings comprise:
• a first main winding wound with a first main winding wire;
• and
• at least two second main windings continuously wound with a second main winding wire separate from the first main winding wire;
• the plurality of secondary windings comprise at least one of:
• a first secondary winding wound with a first secondary winding wire;
• and
• at least two second secondary windings continuously wound with a second secondary winding wire;
• a plurality of winding needles disposed on the winding frames respectively to lead out wire heads of corresponding main winding wires or secondary winding wires respectively;
• and
• a wiring board mounted to the plurality of main windings and the plurality of secondary windings that are connected in the annular shape, upper ends of the winding needles passing through the wiring board;
• wherein the segmental stator is fitted over the rotor assembly and the rotor assembly is rotatable relative to the segmental stator.
