Abstract

The utility model relates to an improvement technology for a motor winding, in particular to an improved motor winding which can achieve high efficiency and save energy, cost as well as labor. The improved motor winding comprises a three-phase 24-groove 2-electrode asynchronous motor, a three-phase 18-groove 2-electrode asynchronous motor and a three-phase 36-groove 4-electrode asynchronous motor, and is characterized in that each stage of coil winding of a motor is coiled from a long-span winding into a short-span winding and the connection of rest parts is unchanged. With reasonable design and simple as well as convenient technique, the utility model which saves cost and energy not only has the advantages of the single/dual-layer motor winding, but also overcomes the disadvantages of the single/dual-layer motor winding.

Description

Motor improvement type winding

(1) technical field:

The utility model designs a kind of improvement technology of motor winding, particularly a kind of energy-conservation, abridged edition, joint worker, motor improvement type winding efficiently.

(2) background technology:

Along with development of science and technology, the model of motor, specification get more and more, and its coil windings is also had nothing in common with each other.At present, motor and immersible pump manufacturer almost are the winding production of carrying out according to international standard or industry standard, with existing three-phase 2 utmost points, 24 groove asynchronous motors and immersible pump is example, wherein mutually every polar curve circle winding is that coil winding becomes the winding of a span to constitute, its distribution is 1-12, the concentric type of 2-11; 2 utmost points, 18 groove threephase asynchronouses (vibrating head) are example, and wherein the distribution of one mutually every grade of coil windings is single bag 1-8, the staggered form of double-contracting 1-9; 4 utmost points, 36 groove asynchronous motors are example, and wherein the distribution of mutually every polar curve circle winding is the staggered form of single bag 1-8, double-contracting 1-9.The shortcoming of Cun Zaiing is like this: the one, big, the invalid length of side of coil windings span, be difficult for shaping, and cause the waste of copper cash; The 2nd, the increase of line resistance causes copper loss and power consumption to strengthen during work, makes that the useful life of motor is too short; The 3rd, winding utilization is low, and the copper material efficient of homogeneity can't improve.

(3) summary of the invention:

The purpose of this utility model provides a kind of motor improvement type winding, its adopt the short inserting-coil process of individual layer make the motor winding winding not only have reasonable in design, technology is easy, and abridged edition, energy-conservation is arranged.

The utility model is to constitute like this: the long span of three-phase 24 grooves, 18 grooves, 2 utmost point asynchronous motors and three-phase 36 grooves 4 utmost point asynchronous motor coil windings is turned to the winding of short span, and it is constant that each one connects.

Advantage of the present utility model: the one, keep the double-deck short distance of having simply again of single layer winding inserting-coil process to save copper cash (can save copper cash 10%-15%) and directly reduced copper loss, raise the efficiency and directly change a coil if any burning out a coil.The 2nd, improve startability, on the basis of saving copper cash, the line resistance reduces, and decreases with electricity so can reduce copper loss when work, improves winding utilization, thereby increases the useful life of motor.

The selection standard of described coil windings short distance is: select for use back each phase winding of motor symmetrical.

In sum, improvement type winding of the present utility model can make motor, immersible pump the production economical with materials, reduce cost, simplify the operation, enhance productivity.That the utility model also has is reasonable in design, connect and be suitable for convenient (its each winding link and wire gauge, the number of turn preceding identical with improvement) and have very big application value.

(4) description of drawings:

Fig. 1 is improvement type winding three-phase 24 grooves 2 utmost points one phase line component cloth expanded views, and its connected mode is preceding identical with improvement;

Fig. 2 is improvement type winding three-phase 18 grooves 2 utmost points one phase line component cloth expanded views, and its connected mode is preceding identical with improvement;

Fig. 3 is improvement type winding three-phase 36 grooves 4 utmost points one phase line component cloth expanded views, and its connected mode is preceding identical with improvement.

(5) embodiment:

This improvement type of Fig. 1 winding offline mode is: two coils that a phase is a group, and the kerve of following first coil of elder generation is every following again second the coil kerve of a groove; First coil kerve of the following again second one group of coil of phase of its septum secundum one groove is every following again second the coil kerve of a groove; Every one group of first coil kerve of following again second phase of a groove, directly press its face groove under the 1-10 then, descend another coil kerve again every a groove, then following groove.So and the like;

This improvement type of Fig. 2 winding offline mode is: two coils that a phase is a group, and the kerve of following first coil of elder generation is every the kerve of following again second coil of a groove; The kerve of single coil of one group of coil of second phase under its septum secundum one groove; The kerve of first coil of one group of coil of third phase under a groove then, then below groove, every the kerve of following second coil of a groove, then again below groove { single double-contracting all press (1-8) come under }.So and the like;

This improvement type of Fig. 3 winding offline mode is identical with Fig. 2.

As from the foregoing, (1-12 2-11) is designed to (1-10) to the utility model embodiment Fig. 1 with 3 original phase winding spans; Fig. 2, Fig. 3 are designed to single double-contracting (1-8) with 3 original phase winding span double-contractings (1-9), single bag (1-8), therefore line group span obviously shortens, the wire rod of coil windings can be saved about 10%-15%, thereby has saved raw material (performance in the production of several years is used of motor after the improvement and immersible pump is good).

It is same as the prior art that the utility model is not stated part.
