Summary:PROBLEM TO BE SOLVED: To provide a technique that drives a motor by using accurate induced voltage waves. SOLUTION: An apparatus 100 is provided for creating an induced voltage wave table. The apparatus includes: an induced voltage detector 400, which detects an induced voltage generated across both ends of each phase of coil of a motor that has coils (21A-28A and 21B-28B) of N phases (N is an integer of two or over); a controller 200, which drives the motor, with coils of other phases excluding the coil of a phase used for acquisition of the induced voltage out of the coils of the N phases at creation of an induced voltage wave table, and a table creating section 300; which creates the induced voltage wave table, using the induced voltage.
