Description

Winding framework structure

Technical Field

The utility model relates to a skeleton, more specifically the winding skeleton texture that says so relates to.

Background

The shaft power of the fan pump load is in direct proportion to the third power of the rotating speed, and the size of the fan pump load can be adjusted by adjusting the rotating speed of the motor. The speed regulation of the motor usually has two technical schemes of frequency conversion speed regulation and pole-changing speed regulation. The frequency conversion speed regulation method needs to be provided with a converter, and the comprehensive cost is higher than that of the pole-changing speed regulation method. The stator winding of the motor is divided into two main types of distributed type and centralized type. The ordinary variable-pole variable-speed asynchronous motor adopts distributed stator windings. The wire embedding work of the distributed stator winding is difficult and the labor cost is high. The centralized stator winding is formed by mounting a wound coil on a salient pole type stator core, is relatively simple in winding and mounting, and is generally used for a low-power shaded pole type single-phase alternating current asynchronous motor. The shaded pole type single-phase alternating current asynchronous motor usually has two rotating speed specifications of two poles and four poles. The efficiency of shaded-pole single-phase ac asynchronous motors is extremely low.

A small ac asynchronous motor for a household appliance represented by an electric fan generally requires a step speed change within a certain range, and an ac asynchronous motor having a stator winding with a center tap is generally used as an electric fan motor. The method has the advantages of low cost, low efficiency of the motor and adoption of the distributed stator winding for the stator winding.

The miniature motor is widely applied to the fields of household appliances and automatic control. The stator of the current miniature asynchronous motor is still in a shaded pole type structure, and the motor efficiency is very low. Therefore, 2017102957904 in the prior art provides a capacitor phase-shifting motor, which effectively improves efficiency by providing four-pole four-winding, but the four-pole four-winding is formed by providing a # -shaped iron core, winding wires around the iron core to form a cross-shaped winding structure, and then disposing a rotor at the center of the winding structure, so as to provide four magnetic fields with an angle of 90 degrees to the rotor, thereby improving efficiency of the motor, but the four-pole four-winding of this structure avoids direct contact between the winding and the iron core by providing four half auxiliary winding frames when the winding is wound on the iron core, and due to the provision of the half auxiliary winding frames, a gap is formed between two adjacent half auxiliary winding frames when the lead is wound on the half auxiliary winding frames, so can demonstrate unsettled setting when the transition wire between two windings passes through the gap, and current winding avoids whole bulky, and consequently the wire that uses generally all is thinner, like this at unsettled in-process that sets up, just appears because the cracked problem of wire that outside extrusion leads to very easily.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a can effectually avoid the unsettled easy cracked winding skeleton texture of wire that leads to of transition wire between the winding.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a winding skeleton texture, includes skeleton and lower skeleton, it all is the cross with lower skeleton to go up the skeleton, go up the cross skeleton texture that has the accommodation space who holds the iron core in can dismantling to be connected to form between skeleton and the lower skeleton, this cross skeleton texture's frame arm is as wire winding portion, set up the through-hole that supplies the rotor to pass on cross skeleton texture's central point puts to be equipped with the support wall that is used for supporting the cross-over line of two adjacent windings on the pore wall of through-hole.

As a further improvement, the support wall of lower skeleton has seted up the wiring groove on going up the border of skeleton one side dorsad, should support the wall and have seted up the wiring hole on being close to the position of last skeleton, through the mode that passes wiring hole and wiring groove with the wiring, will connect the wire outward and bind fixedly to the winding on.

As a further improvement, the upper frame is equipped with the package edge of caving in for the border of the one end of lower skeleton, the lower skeleton is equipped with the edge of inlaying to the expanding for the one end border of upper frame, when the upper frame splices with lower skeleton, inlays in the edge is embedded into the package edge to the cross skeleton texture that has the accommodation space who holds the iron core in the constitution.

As a further improvement, the lower side of the lower frame is provided with supporting legs in the positions corresponding to the winding parts, so that the lower frame is used as a support for the lower frame when being placed on a desktop.

The beneficial effects of the utility model, through the setting of last skeleton and lower skeleton, alright effectual be connected between skeleton and the iron core base of making things convenient for, and through the setting of supporting the wall, alright effectual with the transition wire between two windings live, and then avoid among the prior art because the unsettled easy problem that breaks appears that receives external collision that leads to of transition wire.
