In the process of motor manufacturing technology, the winding wire embedding process of the motor stator plays an important role in the whole technological process of the motor, and the current wire embedding method of the winding is mainly divided into manual wire embedding and machine wire embedding. Among them, in motor design, in order to suppress counter potential harmonics, improve counter potential forward rotation, reduce heat generation caused by counter potential harmonics, and reduce electromagnetic vibration, a stator of a high-speed motor generally employs a double-layer winding. However, with this winding, interlayer insulation needs to be treated, and in the prior art, a machine cannot be used to complete double-layer winding wire embedding and solve interlayer insulation, so only a manual wire embedding method can be adopted. The end part of the manually manufactured motor winding is high in height and low in groove fullness rate, so that the copper loss of the motor is large; in addition, the manual coil inserting efficiency is low, the cost is high, the coil inserting process of the winding is slow, and the whole process of the motor stator is influenced. The existing coil inserting machine can only complete single-layer coil inserting, the manufactured stator slot filling rate is low, the height of the winding end is large, and the copper loss of the motor is also large. In addition, because a certain width requirement is arranged on the motor notch during wire embedding, the motor notch is greatly restrained against the cogging force and the cogging harmonic wave of the motor, and the optimized design direction of the cogging force and the cogging harmonic wave is limited.
The following are two types of coil inserting machines in the prior art:
first kind:
the coil inserting machine (patent CN 208158376U) is used for inserting the motor iron core coil of the coil inserting groove type (namely, the notch is opened inwards). The wire embedding process comprises the following steps: the wound coil is placed on a wire falling cup, then transferred to a wire embedding mould, and the iron core is placed on the wire embedding mould. The coil inserting machine is started, the mechanical arm of the compressing mechanism compresses the stator core, and the coil inserting machine inserts the coil into the stator slot.
However, this device has the following problems:
1) Only single-layer winding coil insertion can be completed, double-layer winding coil insertion cannot be solved, and interlayer insulation cannot be solved;
2) The requirements on the width of the notch are large;
3) The winding end part is high after wire embedding;
4) The groove filling rate is low.
Second kind:
Flying fork winding machine (CN 206349247U), is used for winding iron core of motor with slot (i.e. slot opening), such as stator or rotor of magneto. The winding method comprises the following steps: after the stator is fixed on the jig, the flyer swing arms and the wire arrangement tools arranged on the side edges of the stator are slowly close to the stator, and the flyer swing arms and the enameled wires are driven to rotate by utilizing high-speed movement of the motor. Through winding displacement frock, with the orderly winding of coil round by round in the notch. After one winding, the stator rotates to the position and continues to wind the next slot until all slots finish winding.
However, this device has the following problems:
1) Is not suitable for the coil inserting of the high-slot full-rate motor;
2) Only single layer winding insertion can be achieved.
To sum up, the coil inserting scheme in the prior art has the following disadvantages:
1) The machine coil inserting can not realize double-layer winding coil inserting;
2) The interlayer insulation of the double-layer winding cannot be realized by machine coil insertion;
3) The efficiency of manual wire embedding is low and the cost is high;
4) The heights of the motor winding end parts of the machine coil inserting and the manual coil inserting are too high, so that copper loss is large;
5) The groove filling rate of the machine wire embedding and the manual wire embedding is low;
6) When inserting lines, the motor notch has certain width requirement, so that great constraint is caused to design optimization for restraining motor tooth slot force and tooth slot harmonic wave, and the optimized design direction of the tooth slot force and the tooth slot harmonic wave is limited.
In order to solve the above-mentioned technical problems, the embodiment of the invention provides a motor winding coil inserting device and a coil inserting method.
