4. A single-sided axial flux switching apparatus of a vertical hybrid excitation motor according to any one of claims 1-3, characterized in that: the exciting winding is led out of a stator armature winding through a rectifying module or is directly led in from the outside of the motor, after the motor is started, an outer claw pole can generate wind power towards the direction of an end cover and blows the wind power to the moving sheet and the regulating rod in the annular groove, when the gravity of the moving sheet and the regulating rod is smaller than the received wind power, the moving sheet and the regulating rod which are positioned at the lowest position synchronously and vertically move upwards, the moving sheet and the regulating rod are stopped after the gravity of the received wind power and the moving sheet and the regulating rod reach balance again, at the moment, the regulating rod is connected with a switching point which is closest to the regulating rod on the exciting winding, different switching points are used, the number of turns of the exciting winding of an access circuit is different, the number of turns of the exciting winding of the access circuit is smaller, the axial exciting magnetic flux is also gradually reduced, and a main air gap magnetic field is gradually weakened;
After the rotation speed of the motor is reduced, the wind power is reduced, the moving plate and the regulating rod synchronously move downwards under the action of gravity, the wind power is stopped after being moved downwards to the position where the wind power is balanced with the gravity of the moving plate and the regulating rod, at the moment, the regulating rod can be connected with a switching point on the exciting winding, which is closest to the regulating rod, different switching points are arranged, the number of turns of the exciting winding of the access circuit is different, the more the number of turns of the exciting winding of the access circuit is, the axial exciting magnetic flux is gradually increased, and the main air gap magnetic field is gradually increased.
