Abstract
The invention discloses a method for manufacturing an embedded rotor winding, which comprises the following steps of: 1, bending on a special die to obtain coil unit conductors of which both ends are formed; 2, wrapping end parts and groove parts of the coil unit conductors for insulation to obtain coil units; 3, embedding the coil units of the rotor winding; and 4, welding the coil unit conductors on upper and lower layers by using a head merging sleeve, insulating an end head, binding an end part, dipping into paint, and leading cables out to obtain the rotor winding. In the method, the coil units of which both ends are bent by the die are embedded into a rotor core groove directly from a notch of a semi-open groove of a rotor core, so that the defects that the coil units are difficult to bend manually, the bent coil units are poorly formed, the insulation of the coil units is easy to destroy, hidden quality troubles of a motor are easy to cause, the crushing rate of the rotor winding of the motor is high, labor and time are wasted and the like in the process of manufacturing the conventional large-guage and long-core inserting rotor winding are overcome, the crushing rate of the rotor winding of the motor is reduced, the quality of the motor is ensured, the labor and the time are saved, the work efficiency is improved, and the labor intensity is reduced.
Description
Technical field
The invention belongs to the motor manufacturing technology field, be specifically related to the manufacture method of the embedded rotor winding of a kind of big-and-middle-sized coiling electric motor.
Background technology
As shown in Figure 1 to Figure 3, the rotor winding of common big-and-middle-sized coiling electric motor is generally the wave winding of double-deck full pitch, and its rotor core is a semi-enclosed slot, and the notch size of semi-enclosed slot is less than the coil unit conductor width.In this case, rotor winding coil unit (hereinafter to be referred as coil unit) is made plug-in type rigid line circle usually, its making step is: 1. the end with rotor winding coil unit conductor (hereinafter to be referred as the coil unit conductor) bends on former, and it is straight that the other end keeps; 2. the bare wire coil unit conductor that bends is wrapped insulation, gets coil unit; 3. coil unit is a straight end inserts the rotor core groove, passes manual again bending behind the rotor core groove; 4. with and headgear levels coil unit conductor is welded as a whole, termination insulation, end banding connect outgoing cable behind the dipping lacquer, the rotor winding.
When the rotor number of coiling electric motor few; rotor core is short; isochrone coil unit cross-sectional area of conductor is long-pending little; adopt this conventional plug-in type rigid line circle; roll off the production line than being easier to; coil unit one end bends moulding by mould; the other end is inserted into manual again bending after the rotor core, because the coil unit cross-sectional area of conductor is long-pending little, the required power of bending is little; so than being easier to bending; and because the certain protection measure has been taked in the insulation of coil unit, can not cause damage to the insulation of coil unit usually, the broken pressure rate of rotor winding is not high; and saving working hour, mould are simple relatively.Therefore, the coil unit of Chang Gui big-and-middle-sized coiling electric motor is made plug-in type rigid line circle usually.
And the rotor number of working as coiling electric motor is many; rotor core is long; when isochrone coil unit cross-sectional area of conductor amasss greatly; coil unit adopts conventional plug-in type rigid line circle; the straight manual bending difficulty of an end behind the appearance coil unit insertion rotor core groove; the bending aftershaping is bad; even bend the insulation of having taked good measure protective wire coil unit in the process; still because the increasing of required strength when bending; the very easily insulation of failure line coil unit, and the damage of coil unit insulation can cause the hidden danger of quality of motor again; make the rotor winding break pressure rate height, and the rolling off the production line when quite taking a lot of work of coil unit.
Summary of the invention
The purpose of this invention is to provide the manufacture method that a kind ofly can avoid the insulation of manual bending failure line coil unit, be convenient to the embedded rotor winding that coil unit rolls off the production line.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of manufacture method of embedded rotor winding may further comprise the steps:
1. according to the requirement of coiling electric motor, calculate and design lines coil unit conductor size and shape, on particular manufacturing craft, bend the two ends shape of coil unit conductor, obtain the coil unit conductor of a kind of two ends moulding;
2. wrap the overhang insulation and the slot part insulation of coil unit conductor according to the requirement of insulation standard, reserve coil unit conductor end head part, obtain coil unit;
3. adopt the rotor core of semi-open slot, its notch size, will be embedded in the rotor core groove by the rotor core notch through the coil unit of check and test less than the rotor groove width greater than the single-turn circular coil cell width;
4. routinely technology with and headgear levels coil unit conductor is welded as a whole, termination insulation, end banding connect outgoing cable behind the dipping lacquer, obtain the rotor winding.
The rotor core of the semi-open slot that above-mentioned steps is used in 3., the position that its notch inserts slot wedge is asymmetric abnormally-structured, a side is alignd with the rotor sidewall, the wide rotor sidewall that goes out correspondence of opposite side.
The manufacture method of above-mentioned embedded rotor winding provided by the invention, because rotor core is a semi-open slot, the notch size is greater than the coil unit width, two ends are directly embedded in the rotor core groove by the semi-open slot notch of rotor core by the coil unit that mould bends moulding, avoided existing big wire gauge, in the long plug-in type rotor winding manufacturing process unshakable in one's determination, manual bending difficulty of an end and bending aftershaping straight behind the coil unit insertion rotor core groove that occurs are bad, the very easily insulation of failure line coil unit, cause motor quality hidden danger, make the rotor winding break pressure rate height, many drawbacks such as time-consuming, reduced the broken pressure rate of rotor winding, guaranteed motor quality, and saving of work and time, improve operating efficiency, reduced labour intensity.
