<P>PROBLEM TO BE SOLVED: To provide a drive controller for motor that can drive a motor with high efficiency through a simple processing process with a simple circuit configuration. <P>SOLUTION: A drive controller 1 for motor drives the motor 2 by supplying electric power from an output part 6 of a motor drive control part 3 to winding of the motor 2. The motor drive control part 3 includes a command information generation part 4 and a drive signal generation part 5. A command information generation part 4 is previously stored with an advance value group corresponding to a combination of winding current information on the motor 2 and rotating speed information. The command information generation part 4 selects an optimum advance value from the advance value group according to the combination of winding current information and rotating speed information on the motor 2, and outputs optimum advance value information and speed command information to the drive signal generation part 5. The drive signal generation part 5 outputs a drive signal for the motor 2 to an output part 6 according to the optimum advance value information and speed command information. The optimum advance value is found according to a rotating speed and a winding current of the motor 2 without requiring any complicated operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
