<P>PROBLEM TO BE SOLVED: To provide technology for arbitrarily changing an excited section in accordance with the speed of a drive section in a motor. <P>SOLUTION: The drive control circuit of the motor includes: an original drive signal generating section (in 530) that generates an original signal based on a positional signal (SSA) indicating a relative position of first and second drive members in the motor, an excitation rate signal generating section (700) that generates an excitation rate signal (Er) indicating a rate of an excited section and a non-excited section in the coil of the motor based on a speed signal indicating a relative speed of the first and the second drive members in the motor, an excited section signal generating section (590) that generates a digitized exciting section signal (Ea) determining the excited section and the non-excited section in the coil of the motor based on the positional signal and excitation rate signal, and a mask circuit (in 530) that generates a drive signal for driving the motor by masking the original drive signal based on the exciting section signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
