Abstract

The invention relates to the technical field of motors, in particular to a stator winding structure and a motor. The stator winding structure is characterized in that the stator winding structure comprises a stator core, stator coils and a fixing structure which is used for fixing the stator coils on the side wall of the stator core; the stator coils are arranged to be of a U-shaped structure andcapable of inserting and penetrating the side wall of the stator core along the length direction of the stator core; multiple sets of stator coils are arranged, and one ends of any two adjacent sets of the stator coils are connected through a joint; the stator coils are wound in the way that the stator coils pass through the inside diameter of the stator core and reach the outside diameter of thestator core to wrap around the stator core. The motor comprises the stator winding structure. The stator winding structure has the advantages of alleviating the problem of too long end portion of stator winding, increasing the axial distance of the motor, and thereby solving the technical problem of reducing the critical speed of a rotor. Furthermore, motor speed is increased, and the volume of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator winding structure and a motor. Background technique [0002] With the development of the electric power industry, the application of motors at home and abroad is becoming more and more extensive. Some loads have higher requirements on the speed. However, increasing the speed of the motor will have higher requirements on the performance of the motor. The existing motor Performance is difficult to meet such high requirements. At present, the stacked winding in the stator winding is generally composed of coils of the same shape and size, one or two coil sides are embedded in each slot, and the outer ends of the slots are stacked one by one and evenly distributed. [0003] However, the ends of the existing motor windings are too long, so that the occupied space at both ends of the stator core is large, the bearing distance is increased, the axial distance of the motor is inc...
