Description

The magnetic conductor that motor stator pole shoe module setting-in is used

[technical field]

The utility model relates to the magnetic conductor that a kind of motor stator pole shoe module setting-in is used, and belongs to the part technical field of motor stator.

[background technology]

Traditional motor stator core be laminated by some stator punchings rear integrated, wherein, complete monolithic stator punching edge in its yoke protrudes out the gear piece that several point to the stator punching center, therefore, stator core is comprised of stator yoke section and stator teeth, stator coil is to be wound on stator teeth, and just there is following technical problem in this:

in the stator manufacture process, coiling is inconvenient, namely directly carry out winding operation on stator core, because inlet wire notch (adjacent stators tooth section between gap) is little, cause the winding operation space little, need to purchase the pin type coil winding machine for this reason, and pin type coil winding machine equipment investment cost is high, at present essential import, the producer that financial strength is little can't popularize, still continue to use artificial winding operation, although the pin type coil winding machine that price is more expensive increases compared with artificial coiling work efficiency, but because cost performance is not high, the user still dislikes its threading speed slow, winding efficiency is low, the deficiencies such as wire winding high in cost of production, coiling manufacturing expenses height is reflected to the motor unit cost indirectly to be difficult to descend.

The pin type coil winding machine is in when coiling, only can one stator teeth connect the action that winds the line of a stator teeth ground, the unit interval output that winds the line is little, only can 40 coils of coiling/hour.

[utility model content]

The purpose of this utility model is to provide the magnetic conductor that a kind of motor stator pole shoe module setting-in is used, the structure of this magnetic conductor can become the lamination tabling type motor stator for the pole shoe module setting-in of belt coil, can independently carry out in advance winding operation easily to satisfy the pole shoe module before setting-in, the coiling low cost of manufacture, the motor stator that is formed by the pole shoe module after coiling and magnetic conductor setting-in has the high characteristics of coiling copper factor, thereby has improved electric efficiency.

For addressing the above problem, the technical solution of the utility model is as follows:

The magnetic conductor that motor stator pole shoe module setting-in is used, it becomes lamination tabling type motor stator institute essential for setting-in, described magnetic conductor is replaced stack and is fixedly become isometrical structure by the magnetic guiding loop punching of some layers of closure and the semi-open magnetic conduction ring plate of some layers, every layer of semi-open magnetic conduction ring plate cut sheet by some sections magnetic guiding loops and circumferentially is spaced and forms, and the adjacent magnetic guiding loop of every layer of semi-open magnetic conduction ring plate cuts all to form between sheet and inlays the space in magnetic conductor.

The semi-open magnetic conduction ring plate of the magnetic guiding loop punching of some layers of closure of above-mentioned alternately stack and some layers is by riveting or withhold and fix being connected each other, and the magnetic guiding loop in every layer of semi-open magnetic conduction ring plate cut sheet with equal arc length, equate angle apart from and the semi-open magnetic conduction ring plate of phase interbed in magnetic guiding loop cut the sheet arrangement of aliging.

Compared with prior art, the beneficial effects of the utility model are as follows:

Has the conventional design that motor stator has been answered on the magnetizer structure top of inlaying the space, magnetic conductor becomes the necessary part of motor stator, this magnetic conductor can become the lamination tabling type motor stator for the pole shoe module setting-in of belt coil, can independently carry out in advance winding operation easily to satisfy the pole shoe module before setting-in, the coiling low cost of manufacture, the motor stator that is formed by the pole shoe module after coiling and magnetic conductor setting-in has the high characteristics of coiling copper factor, thereby has improved electric efficiency.

before each pole shoe module assembly becomes the lamination tabling type motor stator, all can independently carry out in advance winding operation easily, abandoned and to have wound the line one by one on traditional stator in traditional winding operation pattern of stator teeth, avoid the interference of stator teeth during coiling, and the impact of the small space between stator teeth and stator teeth, thereby reduced the wire winding requirement, can support the use high speed cable machine equipment, realized that a plurality of pole shoe modules can wind the line simultaneously, threading speed is significantly soaring, unit interval coiling output is high, coiling coiling expense decrease, compare with pin type wire-wound machine, the equipment investment of high speed cable machine is few, can domesticize, output be 150 coils/hour, its return rate is high.

The coiling copper factor is high: carries out the neat winding operation of linear array on the pole shoe module, guaranteed the homogeneity that coil spaces, and the impact of the wire diameter material thickness that do not wound the line, because the coiling copper factor is high, thereby improved electric efficiency;

The magnetic guiding loop that consists of magnetic conductor cuts sheet and can be obtained by the punching of silicon steel sheet leftover bits.
