Abstract
The invention discloses a compound winding motor which comprises an iron core and coils and is characterized in that a gap between the end face of the iron core and the end part of at least one end of the coil is provided with a magnetic conduction member. The magnetic conduction member is arranged in the gap between the end face of the iron core and the end part of the coil, magnetic beams among all phases (all coils) of the motor can be conducted, so that the magnetic beam density of the iron core is reduced, iron loss of the iron core is reduced, and the purpose of efficiency of the motor is achieved. Meanwhile, a copper wire between the end part of the coil and the end face of the iron core is utilized, thus the utilization rate of the copper wire is increased.
Description
Technical field
The present invention relates to field of motors, particularly a kind of concentrated volume motor.
Background technology
The existing concentrated volume motor mode of production generally has following two kinds:
(1) spiral plug-in type working system: this motor coil 1 is in advance on the spiral mould; Transferring to coil after coil 1 spiral is accomplished inserts in the tool; Begin from the notch of 2 bottoms unshakable in one's determination through inserting the action of tool, make the coil 1 spooled then, axially get in the core slots along unshakable in one's determination 2; Thereby accomplish the insertion of motor coil, this kind motor copper factor is high.But because technological reason, in coil 1 insertion process, coil 1 forms an angle with core slots, therefore must make the length of coil 1 be slightly larger than 2 height unshakable in one's determination, can excessive compression between electric wire when guaranteeing that coil 1 inserts and then cause that electric wire line wound etc. is withstand voltage bad.Because coil 1 length is slightly larger than 2 height unshakable in one's determination, after coil 1 inserts, between motor unshakable in one's determination 2 and coil 1 end measure certain clearance 3 is arranged, as shown in Figure 1.This is the existence of clearance space partly, means that not only the wire length of coil 1 increases, and the electric wire use amount increases; The copper cash utilance is lower, and this copper cash that partly increases causes that also motor resistance rises, the increase of motor copper loss; And then cause moyor to descend, hinder the motor high efficiency.
(2) directly coiling working system unshakable in one's determination: this motor manufacture catches on electric wire through a bearded needle and in core slots, moves around core tooth part, makes electric wire directly around the core tooth part position.Because the bearded needle of spooling equipment need move in core slots; So that copper cash one enclose on iron core, therefore need in core slots, reserve the motion space of bearded needle, make that this kind motor groove copper factor is lower; Electromagnetic steel plate employing rate is lower, but the copper cash utilance is higher.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of concentrated volume motor, it has improved the copper cash utilance, and can realize the motor high efficiency.
The objective of the invention is to realize like this: a kind of concentrated volume motor, comprise iron core and coil, it is characterized in that: the gap between the end of at least one end of described end face of iron core and coil is provided with magnetic conductive part.
Gap between the end of described end face of iron core and the positive and negative end of coil is equipped with magnetic conductive part.
Said magnetic conductive part is formed by the folded button of electromagnetic steel plate punching press.
Insulation processing is carried out on said magnetic conductive part surface.
Said magnetic conductive part is fixed in the gap between end face of iron core and the end winding through riveted joint or bonding mode.
Said magnetic conductive part is more than two, be inserted between coil and the iron core respectively after, adjacent magnetic conductive part joins end to end and constitutes an annulus that matees with shape of cross section size unshakable in one's determination.
Described magnetic conductive part comprises tooth portion and yoke portion, fixes with the yoke portion of iron core and the aligned in position of tooth portion respectively.
Chamfered is carried out in the position, tooth portion angle of said magnetic conductive part.
The present invention compared with prior art; Have clear superiority: the gap through between end face of iron core and end winding is provided with magnetic conductive part, can conduct the flux of motor each alternate (between each coil), to reduce flux density unshakable in one's determination; The low iron loss that subtracts iron core; And then reach the purpose of motor high efficiency, and make end winding be able to utilize simultaneously to the copper cash between end face of iron core, improved the copper cash utilance.

Embodiment
The present invention is a kind of volume motor of concentrating efficiently; Like Fig. 2-iron core 2, coil 1 etc. of comprising shown in Figure 7; Adopt the spiral plug-in type to accomplish the installation of coil 1; Therefore between 2 end faces unshakable in one's determination and coil 1 end (anode and anti-end), all have gap 3, the gap 3 between the end of at least one end of the present invention's 2 end faces unshakable in one's determination and coil 1 is provided with magnetic conductive part 4.Preferably, the gap 3 between 2 end faces unshakable in one's determination and coil 1 both ends (anode and anti-end) is equipped with magnetic conductive part 4.Magnetic conductive part 4 can be fixed in the gap between 2 end faces unshakable in one's determination and coil 1 end through modes such as riveted joint or bondings.
This magnetic conductive part 4 is formed by the folded button of electromagnetic steel plate punching press, and insulation processing is carried out on the surface.The structure of magnetic conductive part such as Fig. 2, shown in Figure 3 comprise tooth portion 42 and yoke portion 41.Like Fig. 4, shown in Figure 5; During installation; The tooth portion 42 of magnetic conductive part 4 and the position of yoke portion 41 respectively with unshakable in one's determination 2 the yoke portion 21 and the aligned in position of tooth portion 22; It is fixing that the tooth portion 42 of magnetic conductive part 4 is inserted through motor coil 1 back from space 3 between coil 1 and unshakable in one's determination 2,41 in yoke portion and unshakable in one's determination 2 yoke portion 21 fixed-site, and fixedly the position of back core and magnetic conductive part concerns like Fig. 6.For ease of inserting, the tooth portion of magnetic conductive part 4 preferably carries out 42 jiaos of positions chamfered makes it level and smooth.Install for ease of inserting, magnetic conductive part 4 is preferably by forming more than two.In the example as shown in Figure 3, magnetic conductive part 4 comprises three, be inserted between coil 1 and unshakable in one's determination 2 respectively after, adjacent magnetic conductive part 4 joins end to end and constitutes an annulus that is similar to 2 shape of cross sections unshakable in one's determination as shown in Figure 4 and size.
The annulus that magnetic conductive part 4 constitutes can conduct the flux of motor alternate (between each coil 1), subtracts unshakable in one's determination 2 iron loss to reduce the flux density of iron core 2, to hang down, and then reaches the purpose of motor high efficiency.In addition, coil 1 end is able to utilize to the copper cash between 2 end faces unshakable in one's determination, has improved the copper cash utilance.
