Position control motor based on electronic commutator synchronous motor

摘要

The motor is based on an electronic commutator synchronous motor with two coaxial parts which can rotate relative to each other. Each part comprises a corresponding ferromagnetic core. An essentially cylindrical air gap separates the cores of the two parts. The motor has at least one pair of main poles (2,3,4,5) per motor phase as a carrier for the operating coils which are arranged opposite a tooted rotor (20) of weakly magnetic material. The main poles (2,3,4,5) are subdivided into permanent magnetic exciting pole pairs (10,11). The pole pair division corresponds to the tooth separation of the rotor (20). The exciting poles are staggered the same as the main poles from motor phase to motor phase according to a given equation.
