<P>PROBLEM TO BE SOLVED: To provide a motor drive control device capable of surely starting a motor even if the motor rotates in the forward or backward direction under the influence of a wind or the like when starting the motor. <P>SOLUTION: A motor drive control device 1 outputs drive voltages SU1, SV1, SW1 for driving a motor 51 which can be rotated in the forward or backward direction to drive the motor 51. The motor drive control device 1 comprises a rotational direction detection part 2 and a drive voltage adjustment part 5. The rotational direction detection part 2 detects the rotational direction immediately before starting the motor 51. The drive voltage adjustment part 5 adjusts the drive voltage at a start of the motor so as to be different from a predetermined drive voltage outputted to the motor when the motor starts in the state of no rotation, according to the rotational direction immediately before starting the motor 51 which is detected by the rotational direction detection part 2. When the drive voltage adjustment part 5, in particular, adjusts the drive voltage so as to be larger than a predetermined drive voltage when the rotational direction of the motor immediately before starting is the backward direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
