Description

technical field [0001] The invention relates to a two-phase twenty-pole radial stator and rotor combined field motor. Background technique [0002] At present, the U-shaped or C-shaped stator of the transverse field motor is suitable for the iron core structure of the large-diameter transverse field motor, but not suitable for the small-diameter magnet-concentrating transverse field motor. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a two-phase twenty-pole radial stator and rotor combined field motor. [0004] The technical solution of the present invention is: a two-phase 20-pole radial stator and rotor combined field motor, characterized in that: each set of stators is stacked with an outer stator core, an inner stator core and a transition iron core. The core constitutes a transverse concave stator. The outer stator core and the inner stator core are staggered along the axial cross secti...
