GATE ELECTRIC MOTOR

摘要

A gate electric motor is proposed comprising a salient-pole rotor having even number of poles and an excitation system consisting of two permanent magnets positioned at an angle, vertex of the angle facing opposite the working clearance, and salient-pole stator, a number of poles of which differs from those the rotor poles, wherein each stator pole is surrounded by an identical coil. The motor is characterized in that the permanent magnets of each pole optionally adjoining ribs of unipolar edges, the angle between permanent magnets is about 90° and the rotor parts adjoining the permanent edges, parallel to the direction of magnitization and facing opposite the working clearance, and rotor parts between neighbouring rotor poles adjoining the permanent magnet edges facing the working clearance, parallel to the direction of magnitization, are made from non-magnetic material. The motor can be implemented having e4ither even or odd number of the rotor poles interacting with one group of the stator coils, accordingly, facing the rotor polarity of the stator poles created by coils belonging to one phase, being either like or unlike.
