    Abstract: To present a motor drive control device capable of realizing high speed driving by a simple power feeding control method. The motor drive control device of the invention has a three-phase full bridge circuit for adjusting the feeding phase so as to invert the terminal voltage in feeding-off time, by cyclically repeating positive direction feeding period, non-feeding period, negative direction feeding period, and non-feeding period. In high speed driving, the phase is adjusted so as to invert the terminal voltage right after feeding-off, and if not reaching the desired rotating speed, the feeding time is shortened. As a result, the phase angle to the actual applied voltage can be advanced, and high seed rotation by weak-field system driving is realized. When there is a sufficient allowance in the voltage, the phase is adjusted so as to invert the terminal voltage immediately before turning on the feeding, and the feeding time width is adjusted so that the phase relation of the feeding-off time and the terminal voltage inverting time may be a desired relation and the applied voltage and the current phase are optimized, and the maximum efficiency driving is realized.

    Abstract: Phase correction unit (25) for outputting a commutation signal for switching a winding that allows a current to flow to brushless DC motor (4) and drive unit (16) for outputting a drive signal indicating supplying timing of electric power supplied to brushless DC motor (4) by inverter (3) based on the commutation signal output from phase correction unit (25) are provided so as to maintain a predetermined relation between a phase of a current flowing to a predetermined winding of brushless DC motor (4) and a phase of a voltage. Since brushless DC motor (4) is driven by a signal for holding the predetermined relation between the phase of the current and the phase of the voltage, the stability of drive under high-speed and high-load conditions is enhanced and a drive range is extended.

    Abstract: PROBLEM TO BE SOLVED: To solve the problem wherein no current flow to DC circuits and no current can be detected, thereby drive cannot be performed stably due to voltage drop close to 0 V when the capacitance of smoothing capacitors is decreased for miniaturization.SOLUTION: When a voltage decision means 115 determines that a pulsating bus voltage drops lower than a preset threshold, a control means 114 of controlling a voltage to be applied to a motor 106 from an inverter 105 energizes an output to the motor 106 for an extremely short time so that a DC current becomes a negative current, thus preventing the voltage between DC buses from dropping close to 0 V because the motor 106 charges the smoothing capacitor, detecting current even if the capacitance of the capacitor 103 is reduced extremely, thereby performing stable drive.
