It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into motor rotor and generator rotor. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions.

The supporting legs 2 are used for installation, and the inspection door 3 is used to facilitate regular inspection of the internal drive motor 12, etc.

[0026] A controller 5 is mounted on the left end vertical beam of the U-shaped beam 4, and the controller 5 is electrically connected to the pressure sensor 8. The U-shaped beam 4 is used to mount the hydraulic cylinder 6, etc., and the controller 5 is used to control the start and stop of the pressure sensor 8 and the hydraulic cylinder 6, etc.

[0027] A support plate 14 is installed at the middle position of the lower part of the protection box 1. Rolling bearings 15 are installed at the middle position of the support plate 14 and the middle position of the upper inner wall of the protection box 1. A gear shaft 16 is installed between the upper and lower rolling bearings 15. The gear shaft 16 is connected to a driven gear 17 through a key, and an active bevel gear 18 is installed above the driven gear 17. The support plate 14 is used to install the gear shaft 16. The rolling bearing 15 and the gear shaft 16 cooperate to rotate the driven gear 17 and the active bevel gear 18. The driven gear 17 is used to drive the active bevel gear 18 to rotate, and the active bevel gear 18 is used to drive the driven bevel gear 1903 to rotate.

[0028] A driving motor 12 is bolted to the right of the lower part of the protection box 1, and a driving gear 13 is mounted above the driving motor 12, and the driving gear 13 is meshed with a driven gear 17.

At this time, the active gear 13, the driven gear 17, the active bevel gear 18 and the driven bevel gear 1903 are all rotated, thereby driving the slider 1904 to move inward, so that the four pressing blocks 1905 flatten the pressing piece from the four sides inward. At this time, the driving motor 12 is reversed to return the pressing blocks 1905 to their positions, and the hydraulic cylinder 6 drives the upper pressing plate 7, the pressure sensor 8 and the lower pressing plate 9 to press the pressure piece. When the pressure sensor 8 reaches the predetermined pressure, the hydraulic cylinder 6 no longer moves forward. After the pressing is completed, the hydraulic cylinder 6 returns to its position. The device drives the active bevel gear 18 and the driven bevel gear 1903 to rotate by the driving motor 12, thereby driving the slider 1904 and the pressing block 1905 to translate, which can well flatten the pressing piece that is not placed flat. The quality of the rotor core after pressing is higher; by setting a pressure sensor 8 between the upper pressing plate 7 and the lower pressing plate 9, the pressing force each time can be monitored and controlled in cooperation with the controller 5, so that the pressing effect is better.
