Conversely, if the number of the existing fan blade groups 543 of the air cooling assembly 54 can fully control the temperature rise and the temperature reduction effect of the permanent magnet auxiliary integrated motor beyond the expected value, the load of the rotor 5 of the permanent magnet auxiliary integrated motor is reduced by dismantling the part extension portion 5434 and the blades 5435 fixedly connected with the extension portion 5434, the actual output power of the rotor 5 is larger, and when the actual output power is the same as the actual output power of the rotor 5 exceeds the expected value, the whole dismantling of the part fan blade groups 543 can also be directly performed by dismantling the base 5431, so that the load reduction effect of the rotor 5 is better, the load of the rotor 5 is reduced to a greater extent, and the actual output power of the rotor 5 is increased.
Under the condition that actual output power increases, the rotational speed of rotor 5 is bigger, compare when rotor 5 rotational speed is slow, the produced amount of wind of single blade 5435 also can show to grow, therefore, when cooling effect exceeds anticipated, even if demolish partial blade 5435 or directly demolish partial fan blade group 543, the cooling effect of forced air cooling subassembly 54 also can not too big undulant, still can provide great amount of wind to permanent magnetism supplementary integral type motor inside, satisfy permanent magnetism supplementary integral type motor inside heat dissipation demand, avoid permanent magnetism supplementary integral type motor to lead to its performance limited because of inside high temperature.
It can be understood that, by being provided with the annular boss 531 and installing the air cooling component 54 on the annular boss 531, a larger distance can be pulled between the blades 5435 of the air cooling component 54 and the end surface of the annular fixed disk 53, so that when the air cooling component 54 rotates, the air quantity generated by the blades 5435 can act on the inside of the casing 1 of the permanent magnet auxiliary integrated motor in a large range, thereby enhancing the cooling effect of the air cooling component 54 and improving the efficiency of the air cooling component 54 in controlling the internal temperature rise of the permanent magnet auxiliary integrated motor.
Compared with the prior art, the air cooling component 54 in the implementation can adjust the air quantity at any time along with the heat quantity generated inside the permanent magnet auxiliary integrated motor, namely, the air cooling component 54 rotates along with the permanent magnet auxiliary integrated motor rotor 5, when the rotating speed of the permanent magnet auxiliary integrated motor rotor 5 is higher, the heat quantity generated inside the permanent magnet auxiliary integrated motor rotor is higher, the rotating speed of the opposite air cooling component 54 is higher, the rotating speed of the blades 5435 in the air cooling component 54 is higher, the generated air quantity is higher, the air quantity of the air cooling component 54 is proportional to the rotating speed of the rotor 5, and the changing heat inside the permanent magnet auxiliary integrated motor can be effectively dissipated.
And through setting up the fan blade group 543 of forced air cooling subassembly 54 to the structure of easy dismouting, can assemble sufficient quantity fan blade group 543 according to the inside heat dissipation demand of supplementary integral type motor of permanent magnetism, can deal with the inside heat dissipation demand of supplementary integral type motor of permanent magnetism, also can reduce burden for the rotor 5 of supplementary integral type motor of permanent magnetism, under the same circumstances of input power, the actual output after rotor 5 reduces burden is greater than the actual output before the reduction of burden.
Embodiment four:
When the internal temperature rise of the permanent magnet auxiliary integrated motor is too fast, and the number of the fan blade groups 543 is increased to the maximum value, the internal temperature rise control requirement of the permanent magnet auxiliary integrated motor cannot be met, the screw bolts III 542 are screwed, so that the screw bolts III 542 are tightly meshed with the threaded holes 5310 on the annular boss 531, the screw bolts III 542 drive the compression ring 541 to be pressed downwards towards the direction of the fan blade groups 543, the blades 5435 in the fan blade groups 543 are pressed, the inclined elastic sheets 5432 are pressed by the blades 5435, bending occurs on the base 5431, the blades 5435 move along with the inclined elastic sheets 5432, the included angle between the blades 5435 and the axis of the permanent magnet auxiliary integrated motor rotor 5 is increased, and in this state, the generated air quantity is larger when the blades 5435 rotate, so that after the compression ring 541 presses the blades 5435, the whole air quantity generated when the whole air cooling assembly 54 rotates along with the rotor 5 is also larger, the cooling effect of the air cooling assembly 54 is enhanced, and the efficiency of controlling the internal temperature rise of the permanent magnet auxiliary integrated motor of the air cooling assembly 54 is improved.
In addition, the compression ring 541 presses down the blades 5435, so as to enhance the cooling effect of the air cooling assembly 54, improve the efficiency of the air cooling assembly 54 in controlling the internal temperature rise of the permanent magnet auxiliary integrated motor, and compress the overall height of the fan blade group 543, that is, the overall height of the air cooling assembly 54 will also be reduced, when the space inside the assembled permanent magnet auxiliary integrated motor casing 1 is smaller, in this way, the overall height of the air cooling assembly 54 can be reduced, so as to adapt to the casing 1 with smaller internal space.
It can be appreciated that if the space inside the casing 1 is enough to assemble the air cooling assembly 54 that is not pressed down by the compression ring 541, and the number of the fan blade groups 543 assembled at this time is enough to effectively control the temperature rise inside the permanent magnet auxiliary integrated motor, the compression ring 541 and the bolts three 542 can be removed, so that the overall weight of the air cooling assembly 54 is reduced, compared with the prior art, after the air cooling assembly 54 is assembled on the rotor 5 of the permanent magnet auxiliary integrated motor, the load applied to the rotor 5 is reduced, and the actual output power of the rotor 5 is increased.

The technical scope of the present invention is not limited to the description, but must be determined according to the scope of claims.
