Abstract
A consequent-pole permanent magnet biased bearingless doubly-salient motor includes: a core of a stator/rotor, a middle part of a surface, facing an air gap (), of each stator pole-is grooved toward an edge part of the stator pole-in an anti-clockwise direction, one permanent magnet is attached in each groove, and a surface, facing the air gap (), of each permanent magnet () is the same in polarity; each stator pole-is wounded with an armature coil, the armature coils are serially connected in sequence to form an armature winding, and the armature winding is respectively connected to an external main circuit; and every three stator poles-are wound with a suspension coil, and the suspension coils opposite spatially and radially are serially connected to form a suspension winding connected to an external suspension control circuit.
