Abstract

PURPOSE:To enable to use a cheap small rating switching element by pulse-controlling a switching element, which conducts a brushless DC motor. CONSTITUTION:A detection circuit puts out periodically pulses with the two position ratio according to rpm of a motor. Said pulses perform the two position control of a transistor 5 through the inverters 3, 4a, 4b and also control output pulses of a delay circuit 6. the pulse of the delay circuit 6 inverts ''0'' ''1'' at the same time as the pulse of the detection circuit inverts ''0'' ''1'', which inverting ''1'' ''0'' with a fixed time delay when the output pulse of the detection circuit 1 inverts ''1'' ''0''. When the pulse of the delay circuit 6 turns ''on'', the transistors 11, 12 turn ''on'' to conduct the armature winding 14.
