Description

technical field [0001] The invention is a motor with simple and strong structure, strong torque output capability, high power density and large unit magnetic steel output, which relates to the technical field of motor manufacturing, and in particular a motor related to windings and magnetic circuits. A stator surface-mounted doubly salient permanent magnet motor with complementary and symmetrical structure. Background technique [0002] As the country with the largest reserves of rare earth materials in the world, our country vigorously researches and promotes the application of various new permanent magnet motors represented by rare earth permanent magnet motors, which has important theoretical significance and application value. Over the past decade or so, research hotspots have been focused on rotor permanent magnet motors represented by surface-mounted, plug-in and built-in types. However, the type of motor with permanent magnets placed on the rotor will cause a series ...
