PURPOSE:To smoothly start and rotate a rotor by using only one position detector by performing a conditioning process by a position detection signal from a position detector by a detection signal processor. CONSTITUTION:A position detection signal from a Hall IC6 is distributed by a distributor 100, and a conditioning process is performed by a signal processor 200 to a drive signal generator 300. A slope generator 500 generates a sawtooth wave synchronized with the output signal of a generator winding 7 and a delay pulse to the generator 300. The generator 300 forms 3-phase winding drive signal on the basis of a rotary position detection signal supplied from the circuit 200, a sawtooth wave supplied from the generator 500 and a delay pulse to a drive circuit 700. |
