AI Technical Summary

Technical Problem

Existing motors, while miniaturizing them, struggle to improve operational quality characteristics, particularly power density and maximum output power. They also generate significant noise and vibration, impacting user comfort.

Method used

The stator adopts a modular assembly structure, with each stator assembly including a stator core block, a stator wire frame block, and a stator winding. The stator is formed by connecting the convex and concave parts. Combined with the embedded rotor magnet and the rotor misalignment and pole distribution structure, the winding slot fill factor and magnetic pole distribution are optimized.

Benefits of technology

This technology enables motor miniaturization while improving winding slot fill factor and power density, reducing noise and vibration, increasing maximum output power and operational stability, and enhancing user comfort.

Abstract

The invention relates to a motor and a method for manufacturing the motor, the motor comprises a casing, a stator, a rotor, a front end cover and a rear end cover, the stator comprises a stator core and a stator winding, and the stator core is formed by splicing and enclosing a plurality of stator splicing blocks along the circumferential direction; each stator block comprises a stator magnetic core block, a stator coil holder block and a stator winding, and the stator coil holder block is coated and formed on the surface of the stator magnetic core block and is used for providing insulation isolation for the stator winding; each stator magnetic core block comprises a stator yoke part and a stator tooth, and a stator winding is wound on the stator tooth; the two circumferential ends of the stator yoke part of each stator block are used for being spliced and enclosed with the stator yoke part of the adjacent stator block, so that the stator yoke parts are spliced and enclosed to form a cylindrical outer wall of the stator core, and the inner ends of the stator teeth are spliced and enclosed to form a stator central through hole; and winding grooves are formed between adjacent stator teeth. According to the invention, the winding process is simpler, and the slot fullness rate of the winding slot is improved.
