PROBLEM TO BE SOLVED: To provide a magnet synchronous motor drive circuit which makes the motor drive current a sine wave. SOLUTION: The magnet synchronous motor drive circuit is provided with a motor 1, a detecting section 15 for detecting the rotating angle signals S1, S2, S3 when the motor 1 rotates, and a driving section 16 for generating the sine wave corresponding to the rotating angle signals S1, S2, S3 from the detecting section 15 and supplying the sine wave current to the motor corresponding to the sine wave pattern generated. |
