<P>PROBLEM TO BE SOLVED: To suppress the deterioration of properties caused by the variations of properties among coils, while reducing its cost. <P>SOLUTION: A motor drive device includes a filter 11 which outputs a drive signal based on an input drive command signal S1 and a set drive property value, a PWM drive 12 which outputs a current to be supplied to a coil 2 according to the drive signal from the filter 11, a memory 14 in which parameters requested for every property of a plurality of coils 2 are stored, and a property setter 13 which changes and sets the drive property value that the filter 11 uses, based on the parameter corresponding to an input property selection signal S. <P>COPYRIGHT: (C)2011,JPO&INPIT |
