    Abstract: PROBLEM TO BE SOLVED: To provide a motor drive control apparatus in which control of drive up to the high-speed drive is achieved by a simple method in which the passage of current is controlled. SOLUTION: The motor drive control apparatus repetitively performs a cycle of passage of current in the positive direction, turning the current off, passage of current in the negative direction and turning the current off, in respect of a three-phase bridge circuit, and performs current passage phase adjustment such that, when the passage of current is turned off, the terminal voltage can be inverted. During high-speed drive, the motor drive control apparatus adjusts the phase so that the terminal voltage of the motor may be inverted immediately after the energization is cut off, and when the motor cannot achieve a desired speed of rotation, the motor driving controller exerts control to shorten the energization duration. Due to this structure, the motor drive control apparatus can advance the phase current relative to the voltage actually applied and can implement a rapid rotation by weak field driving. Similarly, when the applied voltage is large enough, the motor driving controller adjusts the phase so that the terminal voltage of the motor may be inverted immediately before the energization and adjusts the length of the energization duration so that the relationship between the phase at the time of energization cut-off and the phase at the time of terminal voltage inversion may be a desired one to optimize the application voltage and the current phase and implement driving of the motor with the maximum efficiency.
