A high-efficiency multi-turn flat copper wire braided spiral wound motor stator

Abstract

The invention discloses a high-efficiency multi-turn flat copper wire braided spiral winding motor stator comprises a stator body, a trough body, insulating paper and flat copper wires. The trough body is arranged on the stator body, the insulating paper is arranged between the inner wall of the trough body and the flat copper wires, the flat copper wire includes a first phase line group A, a second phase line group B and a third phase line group C, the first phase line group A, the second phase line group B and the third phase line group C are set in a braided spiral winding mode. Through theabove mode, the high-efficiency multi-turn flat copper wire braided spiral winding motor stator of the invention has the advantages of high slot full rate, short stator end and relatively copper wiresaving, the used flat copper wires are not entangled, the heat dissipation performance is good, the efficiency is high, and the fault tolerance and redundancy are high.

Description

technical field [0001] The invention relates to the field of motor structure, in particular to a high-efficiency multi-turn flat copper wire braided spiral winding motor stator. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. At present, motor stators with round copper wire windings occupy most of the market. The disadvantages of this motor stator are low slot fill rate and poor heat dissipation performance. see details figure 1 , figure 1 The middle motor stator includes iron core slot 101, round copper wire 102, insulating paper 103, from figure 1 It can be seen that the slot fullness of the stator of this kind of motor is low. Now there is also a card-generating motor with flat copper wires for winding. This card-generating motor utilizes U-shaped copper bars to be directly inserted in the stator core slot in a single form. Although the card-generating m...

AI Technical Summary

Problems solved by technology

Although the card-generating motor solves the problem of slot fullness, because the single-phase winding passes through many slots to form a magnetic field effect, the U-shaped copper strip and the copper strip need to be connected by fusion welding, which will increase the number of welding heads and increase the welding workload. , there is more residual material at the end of the copper strip
