AI Technical Summary
In existing segmented stator technology, as the number of segmented units increases, the number of outgoing wires multiplies, leading to a complex motor assembly process and difficulties in wiring and connection.
Multiple segmented stator units are connected to form a ring stator core, which is wound into series coil windings by enameled wire to reduce the number of outgoing wires. Non-adjacent coil windings are connected by cross segments, and positioning and assembly are performed by fixing fixtures and assembling fixtures.
While maintaining high-density coil windings, the number of outgoing wires is effectively reduced, simplifying the motor assembly process.
