<P>PROBLEM TO BE SOLVED: To provide a motor drive controller which can perform more precise motor drive control with lower noise and lower vibration than before. <P>SOLUTION: The motor drive controller 100 includes a means 20 for acquiring the information of a brushless motor 10, a means 30 for generating control data, a means 40 for outputting a sine wave signal, a means 50 for setting an operation mode, and a means 60 for controlling the drive voltage of the brushless motor 10. The sine wave signal output means 40 has a phase synchronization section 70 and a sine wave generator 42, the phase synchronization section 70 suppresses phase variation of an HG signal, i.e. an input signal, by the smoothing characteristics of a PLL circuit, and the sine wave generator 42 outputs a normalization sine wave signal in which disturbance of waveform is suppressed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
