Description

New energy motor insulation structure

Technical Field

The invention belongs to the technical field of motor insulation, and particularly relates to a new energy motor insulation structure.

Background

In the running process of the new energy motor, the performance, stability and safety of the motor are closely related to the reliability of the internal structure of the motor. Among them, a stator core composed of silicon steel sheets and windings wound thereon play a key role. Under normal working conditions, the windings on the stator core should be in a relatively tight state, but the tight state is not overstretched, but the windings are required to have a firm fixing effect on the stator core, so as to ensure that the windings cannot be loosened due to vibration or electromagnetic force during the operation of the motor.

At present, the traditional motor insulation structure has certain defects in coping with the winding fixing problem. Once the copper wire windings on the stator core come loose, a series of serious consequences can occur. First, the loosening of the windings can cause significant vibration and noise to be generated by the motor when it is running. Vibration in the running process of the motor can influence the overall stability of the motor, so that the motor is difficult to maintain the efficient and stable running state, and the overall performance of the motor is further reduced.

Secondly, loosening of the windings may result in poor contact between the windings and the stator core. The poor contact can obviously increase the resistance, and the increase of the resistance means that under the same current condition, the loss of converting electric energy into heat energy is increased, which can certainly reduce the efficiency of converting electric energy into mechanical energy by the motor, and the waste of energy is caused.

Furthermore, loose windings may rub against each other when the motor is running. Continuous friction between windings can cause the insulation to wear away gradually, and when the insulation wears to some extent, short-circuit or open-circuit faults are most likely to occur. The short circuit can cause the current to increase instantaneously and possibly burn related parts of the motor, and the open circuit can cause the motor to fail to form a complete circuit loop, so that the motor stops working. In addition, the windings are deformed under the mutual friction and abnormal current impact caused by faults such as short circuit, circuit breaking and the like, so that the damage degree to the motor is further increased, the service life of the motor is shortened, and the maintenance cost and the equipment downtime are increased.

The insertion of an insulating slot wedge is also a key element during winding installation. The function of the insulating slot wedge is to further fix the winding and prevent it from loosening. However, in actual operation, when the insulation wedge is inserted, if the stress is not uniform, there is a great damage to the winding. Because the windings are usually fine, uneven stress can cause excessive local pressure, resulting in damage or breakage of the windings. Once the winding is damaged or broken, the motor cannot normally operate, and serious electrical faults such as electric leakage and the like can be caused, so that potential safety hazards are brought to equipment and operators.

The embodiment of the invention relates to a new energy motor insulation structure working principle:

1. Initial installation:

The depth of the mounting groove 3 of the stator 2 is far greater than that of the existing stator reserved for windings. When the windings are installed, the windings are firstly respectively placed in the U-shaped groove body structures on the connecting sheets 8. Because a larger gap exists between the U-shaped groove body structure and the windings, two ends of the windings are respectively placed in the corresponding matching plates 10, and the two ends of one winding are separated from the adjacent windings one by one and are preliminarily fixed through the matching of bolts on the matching plates 10 and screw holes on one side of the connecting sheet 8.

Insulation wedge insertion-when the winding is fully wound in the mounting slot 3 on the stator 2, the insulation wedge is inserted into the mounting slot 3. Because the depth of the mounting groove 3 is deep enough, the winding can be effectively prevented from being extruded by the insulating slot wedge, and the winding is prevented from being stretched or broken under extrusion.

The pressing bar 4 is operated by inserting a wrench into the inner hexagonal grooves 12 at both ends of the driving shaft 31 and rotating the wrench so that the driving shaft 31 is rotated. Two opposite threaded grooves 32 are symmetrically formed at two ends of the driving shaft 31, and along with rotation of the driving shaft 31, two threaded sliding blocks 34 in threaded connection with the threaded grooves 32 slide on the inner wall of the matching groove 33 and approach each other. The insert rod 37 fixedly connected to the insert block 36 inside the threaded slider 34 can stir the arc-shaped poking groove 310 on the outer wall of the connecting ring 6, so that the connecting ring 6 rotates. Because the connecting ring 6 equidistance is offered and is dialled post 5 complex arc groove 7 with extrusion strip 4 both ends, so the rotation of connecting ring 6 can drive two and dial post 5, and then makes extrusion strip 4 gather together along the diameter direction of base 1, produces the extrusion effect to the winding. The winding is effectively prevented from loosening by matching with the insulating slot wedge, and the winding is prevented from shaking when the subsequent motor operates.

2. Buffering and binding assistance for connecting piece 8

When the connecting ring 6 rotates, the gears 22 which are connected with the connecting ring 6 in an equidistant rotating way move along with the rotation of the connecting ring 6. Because the gears 22 are all meshed with the toothed rings 21 arranged at the two ends of the base 1, the gears 22 can rotate while integrally moving.

A threaded rod 23 is fixedly arranged at the axis of the gear 22, a chute 24 is formed on one side of the connecting ring 6 at equal intervals, and a movable bar 25 which is slidably connected with the inner wall of the chute 24 is in threaded connection with the threaded rod 23. With the rotation of the gear 22, the threaded rod 23 rotates, so that the moving bar 25 moves in the axial direction of the connecting ring 6, and a state is formed in which the two moving bars 25 are away from each other.

One side of the moving bar 25 is fixedly connected with the connecting piece 8 through two connecting springs, so that the connecting springs provide a buffering interval when the moving bar 25 drives the connecting piece 8 to move. The winding has movable space when being stretched, the later binding operation is convenient, and the two ends of the winding are outwards moved through the elastic force of the connecting spring, so that the winding is fixed again (the original winding is in a loose state), a large gap is avoided between the winding and the stator 2, and the efficiency of the motor is ensured.

3. Disassembly of the connection ring 6 and the stator 2

When it is necessary to disassemble the connection ring 6 or the stator 2, the driving shaft 31 is reversely rotated so that the screw sliders 34 at both sides of the base 1 are away from each other.

A trapezoidal insert 9 is fixedly connected to one side of the inside of the matching groove 33, which is close to the end of the driving shaft 31, and the trapezoidal insert 9 is inserted into a notch 38 formed in the insert 36 along with the movement of the threaded slider 34.

The inclined surface of the trapezoidal shaped insert 9 presses the insert 36 so that the insert 36 slides in the inner wall of the first recess 35 and compresses the return spring 39, thereby moving the insert rod 37 away from the arcuate poking groove 310. At this time, the connecting ring 6 is not limited by the insert rod 37, so that the connecting ring 6 and the stator 2 can be extruded and disassembled.

While the invention has been described in detail in connection with specific preferred embodiments thereof, it is not to be construed as limited thereto, but rather as a result of a simple deduction or substitution by a person having ordinary skill in the art to which the invention pertains without departing from the scope of the invention defined by the appended claims.
