[0034] When the motor is in use, the rotation of the shaft column 8 drives the rotating fan 202 to rotate, blowing the heat dissipation fins on the outside of the shell 1, so that the heat dissipation oil in the shell 1 is dissipated through the heat dissipation fins on the outside of the shell 1, and at the same time, the rotating rotating fan 202 synchronously drives the inner tooth ring 103, the tooth disc 102, the transmission head 101 and the reciprocating screw 903 to rotate, so that the plug body 904 moves left and right in the liquid guide cavity 1 901. When moving to the right, the slide bar 905 is separated from the top bar 907, facilitating the flow of heat dissipation oil from the long hole of the slide bar 905 and the top bar 907 into the liquid guide cavity 1 901. When moving to the left, the slide bar 905 is in contact with the top bar 907 by the plug body 904, so that the long hole of the slide bar 905 and the top bar 907 is closed, and the heat dissipation oil in the liquid guide cavity 1 901 is squeezed into the liquid guide cavity 2 902 through the pipeline, and the heat dissipation oil is poured from above to the surface of the neutral point stator 6 and the rotor 7, and the heat exchange operation of the neutral point stator 6 and the rotor 7 is performed, and the heat dissipation oil is circulated and cooled on the motor.

[0035] Working principle: when the motor is installed on the equipment, the operator moves the threaded rod 106 in the central hole at the right end of the shaft column 8 to the left by using a hexagonal wrench, so that the threaded rod 106 is in contact with the adjusting piece 104 in the sliding groove 105, and the spring is extruded to the left, and the position of the adjusting piece 104 is adjusted to extrude the spring to the left on the transmission head 101 by the adjusting piece 104, so that the tooth disc 102 and the inner tooth ring 103 are no longer engaged. At this time, the installation of the motor on the equipment is started;

[0036] When the motor is installed, the corresponding position is adjusted according to the installation position, because the weight of the lower horizontal plate of the adjusting frame 404 is greater than that of the upper horizontal plate, the adjusting frame 404 rotates and slides in the limiting slide 402 through the roller 403, and the lower horizontal plate of the adjusting frame 404 is always kept in the lower gravity center position in the shell 1. Then, after the motor is installed and fixed, the threaded rod 106 is loosened to release the contact with the adjusting piece 104, so that the adjusting piece 104 slides to the right in the sliding groove 105 and resets.
