摘要： Currents of sine waveforms can be fed through coils by a relatively small-sized circuit, and thereby, highly dense magnetic storage can be realized with less rotation variations and a driving control circuit of a motor rotating at a low noise level can be provided. A coil of one phase of a three-phase brushless motor is driven with full amplitude at which an applied voltage becomes equal to a source voltage, and a coil of one of other phases is driven with gradually changing voltages so that a current of sine waveform is delivered, and a coil of the remaining phase is driven by feedback control so that a total current flowing through all coils becomes a predetermined current value.

摘要： There is provided a drive control system for sensor-less motor wherein a multi-phase sensor-less motor is driven to rotate by switching a current to be applied to a field coil of each phase depending on the rotating phase of motor and such rotating drive is controlled with the PLL control method and the sensor-less motor is driven with higher reliability. When the motor is to be driven, a desired phase is selected as the detection phase and a voltage (Eu, Ev, Ew) induced on the coil of the detection phase is detected when the power is fed for a short period of time to the field coils except for that of the detection phase. A magnetic pole position of a rotor is detected from the amplitude condition of the detected induced voltage and the power feeding phase of the motor drive is determined based on the result of detection of the magnetic pole position. The power feeding for drive is executed depending on this determination to alternately conduct the detection of magnetic pole position and power feeding for motor drive. Moreover, error detection in the method explained above is executed accurately to quickly and adequately execute the process after generation of a fault.

摘要： A drive control system, with PLL control, drives a rotatable multi-phase sensor-less motor by switching a current of a field coil of each phase depending on the rotating phase of the motor. When the moto is driven, a desired phase is selected as a datection phase, and a voltage induced on the coil of the detection phase is detected when power is fed for a predetermined time to the field coils other than the detection phase. A magnetic pole position is detected from the amplitude condition of the detected induced voltage. Based on this detection, the power-feeding phase of the motor drive is determined. Power feeding and pole position detection are performed alternately.
