Stator winding structure of an axial flux motor,

Abstract

The invention provides a stator winding structure of an axial flux motor, including a stator core having a plurality of stator slots and three-phase windings wound on the stator core, an inner end portion and / or an outer end portion of each phase of the windings being bent toward a yoke portion of the stator core so as to fold the inner end and / or the outer end of the three-phase windings over theyoke portion. The stator core includes a stator core having a plurality of stator slots and three-phase windings wound on the stator core. The size of stator inner and outer diameters after coil embedding can be controlled, and the coil arrangement can be more reasonably made use of space, so that the protruding length of the winding end is greatly reduced. Further, by improving the connection mode of the winding, the folding and shaping of the end of the winding can be realized more easily.

Description

technical field [0001] The invention relates to the field of motor structure, in particular to a stator winding structure of an axial flux motor. Background technique [0002] The existing axial flux motor is also called a disc motor, the stator slots are evenly arranged radially along the radial direction of the disc-shaped stator core, and the stator slots run through the iron core in the radial direction. The inventor found that in the traditional technology, after the stator coil is wound, it is embedded into the stator slot according to certain rules. After the wire embedding is completed, the end of the coil protrudes in the radial direction, which makes the outer diameter of the entire stator smaller in space. Larger and smaller inner diameters. Among them, the larger the outer diameter size, the motor casing size must be increased accordingly to accommodate the stator; the smaller the inner diameter size may affect the installation of the motor shaft, and in extreme...

AI Technical Summary

Problems solved by technology

Among them, the larger the outer diameter, the larger the size of the motor casing must be correspondingly increased to accommodate the stator; the smaller the inner diameter may affect the installation of the motor shaft, and in extreme cases, the coils at the inner diameter of the stator may even interfere with each other.
