Abstract

PURPOSE:To reduce the moment of inertia and improve a start up characteristic of the motor by a method wherein motor driving currents formed in response to the output of magnetic reluctance effect elements are supplied to armature coils through slip rings. CONSTITUTION:The detecting output of the elements 18A, 18B of the magnetic reluctance effect elements is fed to the armature coils LA, LB through differential amplifiers 20A, 20B, emitter follower output amplifiers 21A, 22B, brushes 8A, 8B and slip rings 7A, 7B, and return currents reach to a power source circuit 22 through a slip ring 7C and a brush 8C. By driving currents Isintheta, Icostheta flowing through the coils LA, LB from relating positions previously set of a position detecting element and a field pole, magnetic flux Bsintheta, Bcostheta with the same phases as the drive currents is generated, and electromagnetic torque, whose value is constant and which has no relation to an angle of revolution of a rotor, is obtained by the interlinkage magnetic flux. Thus, the moment of inertia is reduced and the start up characteristic of the motor can be improved.
