The core of the utility model is to provide an axial magnetic flux hybrid excitation motor so as to improve the excitation field adjusting capability of the motor.
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
As shown in fig. 1, an embodiment of the present utility model discloses an axial flux hybrid excitation motor including a stator 100 and a rotor 200. It should be noted that the following embodiments are explained and illustrated based on the case where the motor rotates in a steady state, that is, the rotor 200.
As shown in fig. 2, the stator 100 includes a stator core 103, stator teeth are provided on the stator core 103, an armature coil 101 and an exciting coil 102 are wound on the stator teeth, and when the armature coil 101 is energized with three-phase alternating current, a first rotating magnetic field is formed, and the first rotating magnetic field includes a plurality of magnetic field components having different pole pairs.

As shown in fig. 2, the rotor 200 includes a permanent magnet 201 and a magnetic conductive block 202, and the permanent magnet 201 and the magnetic conductive block 202 cooperate to form a permanent magnetic field, and the rotational speed of the permanent magnetic field is the same as that of the rotor 200, when the exciting coil 102 is energized with direct current, a magnetic field generated by the exciting coil 102 is modulated by the magnetic conductive wave generated by the magnetic conductive block 202 to form a second rotating magnetic field, and the stator 100 and the rotor 200 are coaxially arranged, so that a plurality of magnetic field components of the first rotating magnetic field respectively act with the permanent magnetic field and the second rotating magnetic field to form the torque of the motor. As will be appreciated by those skilled in the art, it is assumed that the pole pair number of the magnetic field generated by the exciting coil 102 when a direct current is applied is P 1 Angular velocity of rotary machine W 1 The number of the magnetic conductive blocks 202 is N fe Angular velocity of rotary machine W fe A plurality of modulated magnetic fields are generated,wherein the polar logarithm of the main component is N fe -P 1 The rotational mechanical angular velocity is (N) fe ×W fe -P 1 ×W 1 )/(N fe -P 1 ). As can be seen from the above formula, when the exciting coil 102 is supplied with direct current, the exciting coil corresponds to W 1 When the exciting coil 102 is energized with ac power, the exciting coil 102 needs to be changed into a multiphase coil to generate a rotating magnetic field with a speed w1, and the embodiment of the present utility model only explains and describes the situation when the exciting coil 102 is energized with dc power, but of course, the exciting coil 102 may be changed into a multiphase coil to be energized with multiphase ac power, and the principle thereof is consistent with the three-phase coil arrangement and the energizing manner of the stator 100 of the conventional motor, which is not repeated herein.
