ELECTRONICALLY COMMUTATED CURRENT NON-COLLECTOR DIRECT CURRENT MOTOR

摘要

An electronically commutated, collectorless direct current motor having a permanent magnet rotor comprised of a cup-shaped hollow cylinder in whose interior an internal magnetic yoke is arranged, an internal stator core and an external stator core. A stator drum winding comprises a plurality of phase windings wound on an insulating body with a portion of the stator winding being commingled with the phase windings in a plurality of slots of a slotted stator. The insulating body has a novel shape for arranging the stator winding thereon and for inserting the insulating body into a plurality of slots of the external stator core.
