[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a high-power, low-energy-consumption adjustable motor permanent magnet product, including a rotor core 1. The outer edge of the rotor core 1 is evenly provided with multiple mounting slots 2. Permanent magnet blocks 3 are movably inserted into each of the multiple mounting slots 2. The permanent magnet blocks 3 are tightly fitted with the slot walls of the mounting slots 2. The multiple permanent magnet blocks 3 are fixedly connected with the same connector 4. One end of the rotor core 1 is provided with a slot 5 corresponding to the connector 4. An external threaded tube 6 is fixedly connected in the slot 5. An internal threaded tube 7 is externally threaded onto the external threaded tube 6. The connector 4 is located between the internal threaded tube 7 and the rotor core 1.

[0023] In the above embodiment, during assembly, the connecting piece 4 can connect multiple permanent magnet blocks 3 together. By picking up the connecting piece 4, multiple permanent magnet blocks 3 can be picked up simultaneously, and the multiple permanent magnet blocks 3 can be aligned with multiple mounting slots 2 on the rotor core 1. The connecting piece 4 is pushed to insert the multiple permanent magnet blocks 3 into the multiple mounting slots 2 simultaneously. The connecting piece 4 is sleeved on the external threaded tube 6, and the internal threaded tube 7 is screwed on the external threaded tube 6. The internal threaded tube 7 can limit and fix the connecting piece 4, thereby locking and fixing multiple permanent magnet blocks 3 at the same time, completing the simultaneous installation of multiple permanent magnet blocks 3. The operation is simple and convenient, effectively improving the convenience of assembling the permanent magnet rotor of the motor.

[0024] Two operating grooves 8 are symmetrically provided on the side of the internally threaded tube 7 away from the connector 4. The operating grooves 8 can improve the convenience of operating the internally threaded tube 7 and improve the convenience of disassembling and assembling the internally threaded tube 7.

[0025] The connector 4 includes a collar 9 that is movably sleeved on the outside of the external threaded tube 6. Multiple connecting plates 10 are evenly fixedly connected to the collar 9. The multiple connecting plates 10 are respectively fixedly connected to multiple permanent magnet blocks 3. The collar 9 can cooperate with the internal threaded tube 7, so that the internal threaded tube 7 can lock and fix the connector 4.

[0026] The outer side of the permanent magnet block 3 is arc-shaped, and the permanent magnet block 3 and the rotor core 1 form a cylinder, which makes the assembled motor rotor smoother.

[0027] Multiple positioning blocks 11 are fixedly connected in the slot 5. Positioning holes 12 are provided on the connecting plate 10. The positioning blocks 11 pass through the connecting plate 10 through the positioning holes 12. The positioning blocks 11 and the positioning holes 12 cooperate with each other to position the connecting plate 10, thereby improving the accuracy of the permanent magnet block 3 installation.

[0028] The permanent magnet block 3 has the same dimensions as the mounting groove 2, which can improve the tightness of the fit between the permanent magnet block 3 and the rotor core 1.

[0029] The positioning block 11 and the positioning hole 12 are both rectangular in shape, which can improve the tightness of the fit between the positioning block 11 and the positioning hole 12, thereby improving the positioning accuracy of the positioning block 11.

[0030] The slot 5 includes a circular slot 13 and multiple branch slots 14. The branch slots 14 are connected to the circular slot 13. The connecting plate 10 is located in the branch slot 14. The circular slot 13 and the branch slots 14 cooperate with each other to limit and hide the connector 4.

[0031] Working principle: During assembly, the connector 4 can connect multiple permanent magnet blocks 3 together. By picking up the connector 4, multiple permanent magnet blocks 3 can be picked up at the same time, aligned with multiple mounting slots 2 on the rotor core 1, and the connector 4 is pushed to insert multiple permanent magnet blocks 3 into multiple mounting slots 2 at the same time. The connector 4 is then put on the external threaded tube 6, and the internal threaded tube 7 is screwed on the external threaded tube 6. The internal threaded tube 7 can limit and fix the connector 4, thereby locking and fixing multiple permanent magnet blocks 3 at the same time, completing the simultaneous installation of multiple permanent magnet blocks 3. The operation is simple and convenient, effectively improving the convenience of assembling the permanent magnet rotor of the motor.
