in the case of clockwise rotation of the permanent magnet rotor 7: each swirl vane 13 on the vane unit 12 receives wind resistance in the counterclockwise direction;
when the clockwise rotation speed of the permanent magnet rotor 7 exceeds a certain threshold value as shown in fig. 6, the counterclockwise torque formed by the counterclockwise high wind resistance driving wheel 14 borne by each swirl vane 13 is enough to overcome the clockwise torque applied to the driving wheel 14 by the driving ring 17, so that each swirl vane 13 deflects anticlockwise along the axis of the driving wheel 14, and at the same time, each driving wheel 14 transmits the torque to the driving ring 17 together, so that the driving ring 17 rotates clockwise by a certain angle against the anticlockwise torque applied to the driving ring 17 by the vortex-shaped torsion spring 18, and the vortex-shaped torsion spring 18 stores elastic potential energy; the swirl blades 13 deflect anticlockwise along the axis of the driving wheel 14, and after the swirl blades deflect to a certain angle, the swirl blades are limited by the driving wheel 14 on the adjacent swirl blade 13, and deflection is stopped.
The motor of the scheme is a constant power motor controlled in real time based on a controller;
when the motor operates, the permanent magnet rotor 7 rotates clockwise, so that the vane units 12 on two sides of the permanent magnet rotor 7 rotate in the stator and rotor cooling bin 11, the vane units 12 drive gas in the stator and rotor cooling bin 11 to rotate in the process of rotating along with the permanent magnet rotor 7, so that rotating gas which rotates around a rotor shaft is formed in the stator and rotor cooling bin 11 as a whole, heat generated by the stator coil 6 is fully diffused into the rotating gas in the stator and rotor cooling bin 11 by the rotating gas in the stator and rotor cooling bin 11, hot air is formed, the rotating gas edge which rotates around the rotor shaft in the stator and rotor cooling bin 11 is continuously discharged in a form of hot air through the exhaust port 5 under the action of centrifugal force, and negative pressure is formed in the central area of the stator and rotor cooling bin 11; meanwhile, the cool air in the air inlet bin 9 flows from the thin end opening 50 to the blade units 12 on one side of the stator end ring 8 under the guide action of the negative pressure and the variable-diameter air guide annular wall 10, and the rotation of the blade units 12 ensures that the cool air flowing from the thin end opening 50 is rapidly thrown away and diffused into the stator and rotor cooling bin 11 to be uniformly heated, so that the continuous cooling external circulation is formed in the process;
when the load torque on the motor output shaft 3 of constant power is large, according to the formula p=t×n/9550, where P is power, n is rotational speed, T is load torque; it is known that the rotation speed of the permanent magnet rotor 7 and the vane unit 12 is lower, the anticlockwise wind resistance of each swirl vane 13 on the vane unit 12 is also lower, the anticlockwise torque formed by the anticlockwise wind resistance of each swirl vane 13 on the driving wheel 14 is insufficient to overcome the clockwise torque applied to the driving wheel 14 by the driving ring 17, each swirl vane 13 is still in limit fit with each limit pile, and further the extending direction of each swirl vane 13 is still consistent with the radial direction of the stator end ring 8, as shown in fig. 5, the tail end of each swirl vane 13 is in the farthest state from the axis of the permanent magnet rotor 7 in structure, the linear speed of the tail end of the swirl vane 13 in the shape is in the highest state, and each swirl vane 13 in the shape ensures stirring strength of nearby gas, thereby ensuring the heat dissipation effect in the low rotation speed state;
when the load torque on the motor output shaft 3 of constant power is small, according to the formula p=t×n/9550, where P is power, n is rotational speed, T is load torque; the rotational speed of the permanent magnet rotor 7 and the rotational speed of the blade unit 12 can be higher, the rotational stirring speed and the strength of the blade unit 12 to the surrounding air are both high, the strength of the cooling air flow in the stator and rotor cooling bin 11 is excessive, and the high rotational speed of the rotor enables the anticlockwise wind resistance of each swirl blade 13 on the blade unit 12 to be higher, so that the working efficiency of the motor is affected under the conditions of low load and high rotational speed; the counterclockwise torque formed by the counterclockwise high wind resistance driving wheel 14 borne by each swirl vane 13 in the scheme is enough to overcome the clockwise torque applied to the driving wheel 14 by the driving ring 17, so that each swirl vane 13 deflects counterclockwise along the axis of the driving wheel 14, and simultaneously, each driving wheel 14 transmits the torque to the driving ring 17 together, so that the driving ring 17 rotates clockwise by a certain angle against the counterclockwise torque applied to the driving ring 17 by the vortex torsion spring 18, and the vortex torsion spring 18 accumulates elastic potential energy; the rotational flow blades 13 deflect anticlockwise along the axis of the driving wheel 14, and then are limited by the driving wheel 14 on one rotational flow blade 13 adjacent to the rotational flow blades 13 at a certain angle, as shown in fig. 5, so that the rotational flow blades 13 are prevented from deflecting anticlockwise along the axis of the driving wheel 14, the effect of necessary blade stirring peripheral space is ensured, at the moment, as each rotational flow blade 13 deflects anticlockwise along the axis of the corresponding driving wheel 14 at a certain angle, the extending direction of each rotational flow blade 13 is changed from the radial extending direction of the initial state, at the moment, the distance between the tail end of each rotational flow blade 13 and the axis of the permanent magnet rotor 7 is smaller than that of the initial state, and therefore the linear speed of the tail end of each rotational flow blade 13 is reduced at the same rotating speed, the windward area of each rotational flow blade 13 in the form is reduced, so that wind resistance of each blade unit 12 is reduced in a self-adaptive manner, and the driving efficiency of the motor under the conditions of high speed and low load is improved;
when a large load is added on the motor output shaft 3 again, the rotation speeds of the permanent magnet rotor 7 and the blade units 12 automatically become low, and each blade unit 12 can be restored to be consistent with the radial direction of the permanent magnet rotor 7 under the action of elastic potential energy accumulated by the vortex-shaped torsion springs 18, so that the distance between the tail end of each swirl blade 13 and the axis of the permanent magnet rotor 7 is increased, the tail end linear speed of each swirl blade 13 is increased, and the stirring effect on surrounding air is improved.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
