Abstract

PURPOSE:To obtain powerful torque without increasing input, by constituting this motor in such a manner that currents are let flow in both directions to the armature windings of the direct current brushless motor. CONSTITUTION:A plurality of hole elements 3, 4 are mounted near a rotor 1, a plurality of differential amplifiers X<1>-X<4> are operated by means of a single-pole direct current power source by the output voltage, a plurality of armature windings W1(W11, W12), W2(W21, W22) are connected among the output terminals of the differential amplifiers X1-X4 of a direct current commutator motor, which changes over currents flowing through the armature windings W1, W2 and turns the rotor 1, and switching elements X10-X40, X11-X41 for letting currents flow in both directions to the armature windings W1, W2 connected to the differential amplifiers X1-X4 in response to an angle of revoltion of the rotor 1 are connected to the differential amplifiers and the terminals of the armature windings. Such a constitution can obtain powerful starting torque without increasing input.
