When the driving motor of the new energy vehicle is working, heat will be generated, and it is necessary to dissipate heat from the stator core in a timely manner. Overheating of the stator core will cause the driving motor to malfunction during operation, and a malfunction of the driving motor during operation will cause the new energy vehicle to be unable to drive normally. Most of the existing heat dissipation methods are natural convection heat dissipation, and the efficiency of natural convection heat dissipation is relatively low, unable to dissipate the temperature in a timely manner, and the practicability is poor. In view of the deficiencies of the prior art, the utility model provides a stator core of a driving motor for a new energy vehicle.

[0008] To prevent the coil from slipping out of the symmetric groove during use, the utility model is improved in that two limiting blocks are fixedly connected in the symmetric groove on the silicon steel sheet, and a suitable gap is left between the opposite surfaces of the two limiting blocks.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-4 , a stator core of a driving motor for a new energy vehicle, including a plurality of silicon steel sheets 1, and a heat dissipation mechanism for heat dissipation is arranged on the plurality of silicon steel sheets 1. The heat dissipation mechanism includes a plurality of heat dissipation plates 2, and the plurality of heat dissipation plates 2 are fixedly connected between the silicon steel sheets 1 and the silicon steel sheets 1. A plurality of heat dissipation openings 3 are formed in the silicon steel sheets 1 and the heat dissipation plates 2. A plurality of symmetric grooves 4 are formed inside the silicon steel sheets 1 and the heat dissipation plates 2. Two limiting blocks are fixedly connected in the symmetric grooves 4 located on the silicon steel sheets 1, and a proper gap is left between the opposite surfaces of the two limiting blocks.

[0022] When the device is in use, first wind the coil through the gap between the limiting plates 5 and wind it into the symmetric grooves 4 on the silicon steel sheet 1 and the heat dissipation plate 2. The limiting plates 5 limit the coil to prevent the coil from slipping out of the symmetric grooves 4. Install the iron core on the stator of the driving motor, and then turn on the motor. When the motor works, the stator iron core generates heat, and the generated heat is discharged out of the iron core of the device through the heat dissipation plate 2 and the heat dissipation opening 3.

[0023] In actual use, it is found that after the driving motor is started, the real-time temperature of the stator iron core cannot be observed. In order to avoid the above problems, in this embodiment, a plurality of mounting openings 6 are provided on the silicon steel sheet 1 and the heat dissipation plate 2 around the periphery of the heat dissipation opening 3, and temperature sensors 7 are installed in the plurality of mounting openings 6.

[0024] In actual use, it is found that when dissipating heat from the stator iron core, the mismatch in size between the heat dissipation plate 2 and the silicon steel sheet 1 will result in poor heat dissipation. In order to avoid the above problems, in this embodiment, the sizes of the heat dissipation plate 2 and the silicon steel sheet 1 are matched.

[0025] In actual use, it is found that non-insulating and heat-conducting materials will cause short circuits in the circuit and damage to components. In order to avoid the above problems, in this embodiment, the material of the heat dissipation plate 2 is an insulating and heat-conducting material.
