Example Embodiment
[0021] The hybrid excitation E-shaped iron core axial magnetic field permanent magnet brushless motor of the present invention includes a first stator, a rotor, a second stator, a permanent magnet, a three-phase concentrated armature winding and a single-phase concentrated excitation winding;
[0022] The first stator and the second stator are located on both sides of the rotor. Each stator has 6 E-shaped iron cores and 6 armature coils. Every two armature coils are connected in series to form a three-phase armature winding. The three-phase armature windings on the two stators are connected in series to form the three-phase concentrated armature windings of the A-phase, B-phase, and C-phase of the whole motor; each stator has 6 excitation coils, all of which are Concentrated winding, wound on the teeth in the middle of the stator E-shaped iron core, the above 6 coils are connected in series end to end in sequence to form a single-phase concentrated excitation winding;
