Abstract

The invention relates to an improvement technology of a motor winding, in particular to an improved winding of a material-saving and efficient motor, also called as a preferable winding of a motor. The winding comprises a coil, wherein the coil is wound in stator slots, and the number of the stator slots is more than 24. The winding is characterized in that: each coil winding of the motor is formed by winding the original coil winding of one long span into two or more windings with a plurality of short spans. By adopting a short-span preferable winding method, the coil winding of the motor has the advantages of reasonable design and convenience for connection and use, and greatly saves copper wires; and the wires can be saved by 10 to 20 percent, even about 30 percent, the copper consumption is remarkably reduced, and the efficiency is improved.

Description

Motor improvement type winding
(1) technical field:
The present invention relates to a kind of improvement technology of motor winding, particularly a kind of material-saving, motor improvement type (short span) winding efficiently also claim motor preferably short span winding.
(2) background technology:
Along with development of science and technology, the model specification of motor is more and more, and its coil windings is also had nothing in common with each other.At present, motor manufacturer carries out the production of winding according to international standard or industry standard, is example with existing three-phase 24 grooves 4 utmost point asynchronous motors, and wherein mutually every polar curve circle winding a becomes the winding of a span to constitute by coil winding, be arranged as 1-6 as Fig. 1,7-12,13-18,19-24, like this, the shortcoming that exists is: the one, and the coil windings span is big, the invalid length of side, thus caused the waste of copper material; The 2nd, the line resistance increases during motor work, causes copper loss and electrical loss to strengthen, and makes that the useful life of motor is short; The 3rd, winding utilization is low, can't improve with same copper material utilization ratio.
(3) summary of the invention:
The objective of the invention is to provide a kind of motor improvement type (short span) winding (also claiming motor preferred " short span " winding), it adopts the preferred winding of short span, it is reasonable in design to make that the motor winding winding not only has, connect advantage easy to use, and have material-saving, consumption reduction, remarkable advantage efficiently.
The present invention constitutes like this, it comprises coil, coil winding is in stator slot, and number of stator slots is characterized in that more than 24 grooves: the every polar curve circle of described motor winding is the winding formation that the winding technique of the original long span of coil is become a plurality of short spans more than two or two.
The selection standard of the short span of described coil windings is to select for use back each phase winding of motor can turn to symmetrical structure.
Described coil windings can be carried out parallel connection, series connection or and unites and carry out the coiling use according to its homopolarity same sex.
The present invention is that the design of Windings that is a long span at original one mutually every polar curve circle winding is the winding of a plurality of short spans more than two or two, and this preferred winding of making of improving one's methods has the following advantages:
1, the present invention is because coil windings adopts the preferred winding process of short span, many sizes have been shortened than original span, so reduced the invalid edges of winding, under the constant situation of every utmost point winding total number of turns, also just significantly saved copper cash (can save wire rod 10%-20%, even save about 30%), reduce copper loss, improved efficient.
2, because the line resistance reduces,, improve winding utilization, thereby increase the useful life of motor so when work, can reduce copper loss and electrical loss.
In sum, improvement type winding of the present invention can make motor manufacturer significantly save material, reduce cost, and the motor user is played energy-conservation, consumption reduction, increases profit.
In addition, the present invention also has reasonable in design, connects advantage easy to use, and it is applicable to the improvement of various motor windings, has bigger application value.
(4) description of drawings:
Fig. 1 is the expanded view of existing three-phase 24 grooves 4 utmost point asynchronous motors one phase winding.
Fig. 2 is the short span windings of three-phase 24 grooves 4 utmost point asynchronous motor improvement types of the present invention, the wherein expanded view of W phase winding.
(5) embodiment:
With reference to Fig. 2, the embodiment of the invention comprises coil, and coil winding is in stator slot, and number of stator slots is 24 grooves, it is characterized in that: the every polar curve circle of described motor winding a becomes the winding of two short spans to constitute the winding technique of an original long span by coil.
The selection standard of the short span of above-mentioned coil windings is to select for use back each phase winding of motor symmetrical.
Above-mentioned coil windings a can carry out parallel connection, series connection or and unites and carry out the coiling use according to its homopolarity same sex.
The layout of two windings of every utmost point can further specify as follows in the embodiment of the invention improvement type winding:
W be arranged as mutually (1-5,2-6), (7-11,8-12), (13-17,14-18), (19-23,20-24).
V be arranged as mutually (3-7,4-8), (9-13,10-14), (15-19,16-20), (21-1,22-2).
U be arranged as mutually (5-9,6-10), (11-15,12-16), (17-21,18-22), (23-3,24-4).
As from the foregoing, embodiment of the invention W phase winding span is designed to (1-5,2-6), and being designed to of original motor W phase winding span (1-6), therefore, the winding span has more obviously shortening, and the wire rod of coil windings can be saved 10%-20%, even save about 30%, thereby significantly raw material have been saved.
In use, 1 slot coil extended line can be connected with 13 slot coil extended lines, 8 slot coil extended lines are connected use with 20 slot coil extended lines, perhaps 8 slot coil extended lines are connected use with 13 slot coil extended lines.
It is same as the prior art that the present invention does not state part.
