Embodiment Construction
[0027] The following is an example of a 36-slot three-phase four-pole cross winding.
[0028] A method for preparing a high-efficiency AC motor stator winding, including winding, threading, and wire embedding processes.
[0029] The winding process is: each phase U, V, W has six coils U1, U2, U3, U4, V1, V2, V3, V4, W1, W2, W3, W4, wherein each phase has six coils wound continuously After winding, the coils have the same winding direction, and there are no joints between the 6 coils of each phase; among them, W1, W3, V2, V4, U2, and U4 all include 2 large coils, and the span of the large coils is 1 to 9 slots. W2 , W4, V1, V3, U1, and U3 are all a small coil with a span of 1 to 8 slots.
[0030] The threading process is after the winding process and before the embedding process. The function of the threading process is to make the winding direction of the large coil and the small coil of each phase opposite. The threading process includes:
[0031] (1) Place the wound coils...

Abstract
The invention discloses an effective alternating-current motor stator winding preparation method. The effective alternating-current motor stator winding preparation method includes wire wrapping, wiring and wire inserting. The wire wrapping technique includes that each phase U, V or W has six coils U1, U2, U3, U4, V1, V2, V3, V4, W1, W2, W3 and W4, wherein 6 coils of each phase wrap continuously, the wrapping directions of the wrapped coils are consistent, and there is no joint between the six coils of each phase; each of the W1, W3, V2, V4, U2 and U4 comprises two large coils, the span of the large coil is 1 to 9 tanks, the W2, W4, V1, V3, U1 and U3 are small coils, and the span is 1 to 8 tanks. The wiring is performed after the wire wrapping technique and before the wire inserting technique, and the wiring enables the wrapping directions of the large coils of each phase to be opposite to the winding direction of the small coil. The effective alternating-current motor stator winding preparation method is good in coil winding technique, enables the cost to be saved and enables the motor winding reliability to be improved.
Description
technical field [0001] The invention relates to a method for preparing a high-efficiency AC motor stator winding, and belongs to the technical field of motor stator manufacturing. Background technique [0002] The three-phase stator winding of a three-phase asynchronous motor, after being fed with three-phase symmetrical alternating current, will generate a rotating magnetic field, which cuts the rotor winding, thereby generating an induced current in the rotor winding, and the current-carrying rotor conductor acts on the rotating magnetic field of the stator The electromagnetic force will be generated, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate, and the direction of rotation of the motor is the same as that of the rotating magnetic field. [0003] The stator winding is an important part of the motor, and its welding quality and resistance directly determine the reliability and energy efficiency of the motor. [0004] In the pr...
