Abstract

PURPOSE:To simplify the constitution by a method wherein the current supply section of the three phase stator winding is allowed to be controlled based on the output signals from the two position detecting elements installed along the rotor with the interval of the specific angle or less. CONSTITUTION:Two position detecting elements 1ps, 2ps are installed with an interval of the mechanical angle alpha(alpha<=2pi/3) along the external circumference of the rotor of the brushless motor containing the three phase stator winding. Each output signal waveform is shaped in order that the width of the output signal from the position detecting element 1ps can be 2pi/3 and the output signal width from the position detecting element 2ps can be 4pi/3 at each fall time, and thereafter, these shaping signals 1ps', 2ps', are put into the arithmetic circuit 7. The arithmetic circuit 7 includes the invertor 8 and the logical element 9 for the purpose to form the priority sequence of 1ps'>2ps' against the signals 1ps', 2ps'. Furthermore, it also includes the logical element 10 for the purpose to form the signal of 2pi-(1ps' U2ps'), and emits each winding current supply period control signal U, V, W.
