Abstract
The utility model discloses a synchronous motor pole coil. The pole coil is mainly composed of a copper flat wire, insulated gaskets and leading-out wire connectors. The insulated gaskets are arranged between the turns of the copper flat wire. The leading-out wire connectors are arranged at edges of a head coil and an end coil of the copper flat wire. The leading-out wire connectors and the coils of the copper flat wire are a continuous and entire wire. Solderless joint is adopted between the leading-out wire connectors and the edges of the head coil and the end coil of the copper flat wire. The leading-out wire connectors are bended and shaped through a body wire of the edges of the head coil and the end coil. Compared with a traditional salient-pole synchronous motor pole coil structure having a soldering head, the synchronous motor pole coil of the utility model is advantaged in high reliability and good integrity and is capable of improving operation reliability of the salient-pole synchronous motor.
Description
Technical field
The utility model relates to a kind of synchronous machine pole coil.
Background technology
In synchronous machine, the main effect of pole coil is: during the synchronous machine operation, feed the direct current electricity in the excitation winding that on magnetic pole, is made up of pole coil, set up excitation field.Its magnetic flux comes out from N utmost point pole core, constitutes the loop through air gap, stator core, air gap, entering S utmost point pole core.Traditional salient pole synchronous electric machine pole coil structure is made up of copper strap wire, turn-to-turn insulation liner, pinout connector at present.
For traditional salient pole synchronous electric machine; There is a problem in the pole coil structure; That is exactly: pinout connector is a part independently; Joint and pole coil initial and end circle coil side link together with solder brazing, and each joint and coil side have two weld seams, during weldering second weld seam because conduction of heat can influence the welding quality of article one weld seam.Pole coil will bear the effect of electromagnetic force and mechanical force during the synchronous machine operation, and motor often has exciting current overexcitation operating mode, and pole coil also will bear the overcurrent effect.If there is defective in the joint welding quality, will cause the joint sealing-off, joint breaks away from when serious.Above phenomenon all can cause great quality accident, and the example that motor is reprocessed happens occasionally.Salient pole synchronous electric machine pole coil joint is because of welding the problem that influences pole coil quality and running reliability of motor.
Summary of the invention
It is a kind of not only simple in structure, easy to maintenance that the purpose that the utility model is wanted is to provide, and the salient pole synchronous electric machine pole coil structure that reliability is high, fault is few.
The technical solution of the utility model is: a kind of synchronous machine pole coil; Form by copper strap wire, insulating cell and pinout connector; Turn-to-turn at copper strap wire is provided with insulating cell, is provided with pinout connector at the initial and end coil side of copper strap wire, and pinout connector and coil copper strap wire are a continuous whole line; Pinout connector and copper strap wire initial and end circle limit do not have welding, through this line of initial and end coil side the pinout connector bending are shaped.
The effect of the utility model: compare with traditional salient pole synchronous electric machine pole coil structure, the solderless fitting pole coil has joint and is connected this line of connector by using initial and end coil side o ing with initial and end circle pole coil limit solderless.The pole coil good integrity can the outlet joint breaking under the various operating conditions of motor and the phenomenon of disengaging.Salient pole synchronous electric machine runnability and reliability have been improved; Simple in structure, easy to maintenance.

Embodiment
Below in conjunction with figure and embodiment the utility model is described further.
Comprise copper strap wire 2, pinout connector 3 and insulating cell 1 like Fig. 1, the described pole coil of the utility model shown in Figure 2.The pinout connector 3 and the coil copper strap wire 2 of copper strap wire coil are a continuous whole line, and pinout connector 3 does not have welding, this line of initial and end coil side o ing of pinout connector 3 connector by using copper strap wires with the initial and end coil side of copper strap wire 2.Become pole coil integral body after hot-forming.The shape and the number of turn of flat type copper wire 2 coiled pole coil drawing requirement on strip on edge winding machine bend out pinout connector 3 at the end of the initial and end circle coil side of flat type copper wire 2.Turn-to-turn at copper strap wire 2 is provided with insulating cell 1, makes the copper strap wire 2 of pole coil become firm integral body with insulating cell 1 through hot pressing.
