Abstract
PURPOSE:To reduce vibration and noise, by distributing each current conducted to multiple stator windings into the output ratio of a position signal outputted in a position signal arithmetic circuit. CONSTITUTION:A brushless motor has a permanent magnet 1 and stator windings 2a-2c and is composed of a position signal arithmetic circuit 9, a stator winding drive circuit 6, etc. The position signal arithmetic circuit 9 is composed of rectification circuits 3a-3c, conversion circuits 4a-4c, integration inhibiting command circuits 20a-20c, switches 26a-26c, etc., so as to operate the position signal of a rotor 1 and to output the three-phase position signal. With a modulation circuit 30, an analogue current generation circuit 40, a synthesis circuit 50 and a command comparison circuit 61, the current conducted to stator windings 2a-2c is modulated. The phase changeover flowing to windings 2a-2c is thereby performed smoothly and the vibration and noise in driving the motor is reduced.
