Description

Technical Field

[0001] The utility model belongs to the technical field of stator cores, and particularly relates to a novel electronic core. Background Art

[0002] The stator core is an important part of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and the rotor, it forms the complete magnetic circuit of the motor. This ensures the formation and maintenance of the magnetic field inside the motor, providing the basis for the normal operation of the motor.

[0003] The electromagnetic vibration noise of the electric motors in some existing new energy vehicles is related to the frequency and amplitude of the electromagnetic force wave in the air gap magnetic field on the one hand, and to the natural frequency of the motor itself on the other hand. The electromagnetic vibration noise of the motor is caused by the radial electromagnetic force wave frequency being close to the natural frequency of the motor, which triggers resonance. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of electronic iron core. Through the setting of the connecting block, the coils are wound on both sides of the connecting block and are all inside the wire slot 2 opened in the center. Since the number of connecting blocks is several and they are arranged in a ring shape, the coils wound around the stator disrupt the original regular magnetic field, thereby solving the problem that the frequency of the existing radial electromagnetic force wave is close to the natural frequency of the motor, the electromagnetic vibration of the motor generates noise and causes resonance.

[0013] 1. The utility model arranges a connection block, specifically, by the arrangement of the connection block, the coil is wound around both sides of the connection block and is inside the second wire slot opened in the center.

The utility model arranges the connecting block 31, specifically, by arranging the connecting block 31, the coil is wound on both sides of the connecting block 31, and all are inside the wire groove 2 311 opened in the center. Since the number of the connecting blocks 31 is several and they are arranged in a ring, the coil wound around the stator disrupts the original regular magnetic field and staggers the frequencies of the two, thereby slowing down the resonance phenomenon, making it more stable and reducing noise during operation.

[0026] A limiting ring 22 is fixedly connected to the bottom of the inner ring 1, a fixing ring 2 is arranged outside the limiting ring 22, a plurality of heat dissipation holes 21 are opened at the bottom of the fixing ring 2, and the plurality of heat dissipation holes 21 are arranged in a circular array, and a plurality of card slots 211 are opened inside the fixing ring 2, and the plurality of card slots 211 are arranged in a circular array.

[0027] A plurality of sliding grooves 3 are provided at the bottom of the inner ring 1 , and the plurality of sliding grooves 3 are arranged in a ring array. The outer surfaces of the plurality of connecting blocks 31 are fixedly connected with buckles 32 , and the buckles 32 are adapted to the buckle grooves 211 .

[0028] A slot is formed on the front of the fixed block 12, and a slider 4 is in contact with the inside of the slot. A spring 42 is fixedly connected to the back of the slider 4, and a limiting block 41 is fixedly connected to the front of the slider 4. There are two sliders 4.

[0029] The two sliders 4 are symmetrically arranged with the spring 42 as the center, and there are two limiting blocks 41, which are symmetrically arranged with the spring 42 as the center. The utility model sets the limiting block 41, specifically by pressing two buttons 53 at the same time, so that the limiting block 41 shrinks inward, cancels the restriction on the fixed block 12, and allows the staff to directly remove the connecting block 31 fixed at the bottom of the fixed block 12, which makes the winding simple and quick when the coil is wound, and is more convenient whether it is to be repaired or replaced, thereby increasing the convenience of the device and improving the work efficiency of the staff.

[0030] A sliding groove 2 5 is provided on the side of the fixed block 12 away from the spring 42 , and the inner wall of the sliding groove 2 5 contacts a sliding block 2 51 , a fixing rod 52 is fixedly connected to the front of the sliding block 51 , and a button 53 is fixedly connected to the front of the fixing rod 52 , and the sliding blocks 2 51 are symmetrically arranged.

[0031] A specific application of this embodiment is: the coil is wound on both sides of the connecting block 31, so that a part of the coils on both sides are in the wire slot 2 311. Since there are several connecting blocks 31 and several connecting blocks 31 are arranged in a ring shape, the coil wound on the stator disrupts the original regular magnetic field and staggers the frequencies of the two, thereby slowing down the resonance phenomenon, making it more stable and reducing noise during operation. Since the outer surface of the inner ring 1 is provided with several sliding grooves 13 and is adapted to the connecting block 31, the connecting block 31 can be easily disassembled. The arrangement of several cooling holes 11 allows the coolant to cool the coil through the cooling holes 11, so that the device can maintain a suitable temperature for operation. When the device needs to be repaired or replaced, the buttons 53 on both sides of the fixing block 12 can be pressed to make the two buttons 53 simultaneously push the two sliders 2 51 in Slide inside the sliding groove 25. Since several fixed blocks 12 are connected in a ring-shaped arrangement head to tail, the slider 251 will apply pressure to the two limiting blocks 41, so that the two sliders 14 squeeze the spring 42 at the same time. After the limiting block 41 shrinks into the interior, the staff can directly lift the fixed block 12, and at the same time, lift out the connecting block 31 fixed at the bottom thereof for inspection and replacement. The setting of the limiting ring 22 can limit several connecting blocks 31 so that they will not detach from the device, making the device run more stably. The several heat dissipation holes 21 opened on the top of the fixed ring 2 will cool down the device as a whole. The card groove 211 opened on the inner wall of the fixed ring 2 is adapted to the several connecting blocks 31, so that the fixed ring 2 can fix the coil and make the device as a whole more compact and more stable, and will not vibrate during operation, making the device run more stably.
