Embodiment
[0007] Embodiment: A two-phase 20-pole radial stator and rotor combined field motor, each group of stators 3 consists of outer stator core 4, inner stator core 5 and transition core 6 riveted by stacked rivets of iron core punching sheets A horizontally concave stator 3 is formed, the outer stator core 4 and the inner stator core 5 are staggered by a pole pitch along the axial cross section, the two-phase stator 3 is relatively staggered by half the pole pitch, the outer stator core 4 and the inner stator core The length and height of the sub-iron core 5 are the same. The stator 3 is limited by the end plate 7 on the housing 1 in the four directions of up, down, left, and right, and is fixed in the housing 1 by bolts. There are rotor spokes 9 on the rotating shaft 8, and the rotor spokes 9 has a rotor excitation ring 12 formed by alternating permanent magnet poles 10 and rotor cores 11, and adjacent permanent magnets 10 magnetic poles on the rotor excitation ring 12 are opposit...
