Abstract

PURPOSE:To maintain the rotation of a DC rotary motor in a predetermined direction by eliminating the improper starting point of the motor with a rotor having a magnetic field including a magnetic flux distribution mixed with a predetermined basic wave distribution and harmonic wave distribution and predetermined poles corresponding to the distribution of the magnetic field. CONSTITUTION:A rotor is constructed by forming a magnetic flux distribution a of a field 3 in a distribution so synthesized that a basic wave distribution a' approximately coincides, for example, with double of the harmonic wave distribution a'' of the basic wave distribution a' and by coupling two poles 4 corresponding to the basic wave poles of the field 3 and the four poles 5' corresponding to the harmonic wave poles of the field 3 to the same shaft 6. When the basic wave poles of the field 3 are disposed in the same polarity as the basic wave corresponding poles 5 of the rotor, the center of the poles 5' corresponding to the hormonic wave of the rotor is disposed, for example, at 90 deg. with respect to the harmonic wave distribution a'' of the field 3, and the excitation of the field 3 is switched in response to the position of the poles 4 corresponding to the basic wave of the predetermined rotor, thereby obtaining the rotation of predetermined direction of the rotor.
