Abstract

PURPOSE:To obtain a commutatorless motor with small torque ripple by arranging hall devices at the central part between motor windings wherein a sine wave current which is in-phase with each phase armature winding speed electromotive force is flowed from phase shifted hall device output voltages. CONSTITUTION:Three hall devices are provided between windings having a field system energized by eight-pole equalizing pitches and arranged by six-winding equalizing pitches. As to the U phase circuit 10A in a motor control circuit, a positive phase input terminal voltage Vm becomes a mean value of V1A+V2B and a negative phase input terminal voltage Vn becomes that of V1B+V2A by inputting the output voltages V1A and V1B of the hall device 1 and the output voltages V2A and V2B of the hall device 2 to an operational amplifier 30 respectively. Therefore, the common collector potential VU in transistors 16, 17 is fed back to balance the difference between Vm and Vn, so the common collector potential VU becomes a differential voltage amplification value between Vm and Vn and is in-phase with U phase speed electromotive force to close to a better sine wave.
