ABSTRACT:
A dc brushless electromagnetic rotary machine, such as a dc electric motor, a dc electrical generator, includes a rotor having a permanent magnet which is cylindrical outer peripheral surface magnetized in the same polarity. The outer surface faces armature cores fixed on the inner cylindrical surface of a casing frame forming a stator of the machine. In the structure, the magnetic flux emanating from the rotor magnet passes the armature cores and returns to the magnet from a position other than the armature cores. The armature core is provided with coil windings wound thereon in such a manner that a portion of the windings is included in the air gap formed between the rotor magnet and the cores. Additional magnetic flux induced in response to current flowing over the armature windings causes the main magnetic flux generated from the rotor magnet to be turned in the same way irrespective of the angular position of the rotor. Consequently, continuous rotation of the rotor will be accomplished in the case of dc motors, and continuous generation of dc power will be achieved in the case of dc generators.
