Problems solved by technology

It has the following characteristics: 1. The flat wire conductor is bent and formed at one time, including the head, leg, straight line, and pre-formed point. The two legs of the conductor and one pre-formed point are the welding side, and the head is the non-welding side; Many folding steps, complicated control and low efficiency
2. The torsion direction of the welding end has poor consistency, the height, appearance and form of the bending part are inconsistent, and the bending part cannot be consistent
3. The process is complicated. The preformed flat wire conductors are rolled off one by one from the inner diameter of the stator core to the outside. Since the preformed flat wire conductors are only suitable for the stator core with an open slot, slot wedge support is required.

Abstract

The invention discloses a phase winding which is formed by stacking more than one coil ring. Each coil ring is formed by connecting a plurality of combined coils end to end, and each combined coil isat least formed by winding a first kind of partial U-shaped conductor and a second kind of partial U-shaped conductor, wherein each of the first-class partial U-shaped conductor and the second-class partial U-shaped conductor comprises a head part, two supporting leg parts and two supporting legs which are connected with one another, and the two supporting legs of the same conductor are deflectedtowards the same side; the supporting legs of the first kind of partial U-shaped conductors and the supporting legs of the second kind of partial U-shaped conductors are opposite in deflection direction, and the connecting head parts and the two supporting leg parts of the first kind of partial U-shaped conductor and the second kind of partial U-shaped conductor are overlapped with each other. Bythe adoption of the phase winding, a bridging distance is short, the use amount of the invalid copper is reduced, and the serialized production and design are facilitated.

Description

Technical field: [0001] The invention relates to a phase winding, in particular to a stator phase winding of a motor. Background technique: [0002] Motors (including motors and generators) are devices that convert electrical energy into mechanical energy (or convert mechanical energy into electrical energy) based on the principle of electromagnetic induction. Power source or generating device. Motors can be divided into DC motors and AC motors according to the type of their working power, and AC motors can be divided into single-phase motors and multi-phase motors (such as three-phase motors, etc.). The motor includes a stator and a rotor, and a winding is arranged in a stator core slot of the stator. [0003] There are two types of existing motor windings: wave winding and stacked winding. For segmental hairpin winding motors using flat copper wires or copper wires with rectangular cross-sections, the use of stacked windings will cause too many jumper conductors between ...
