Abstract
PURPOSE:To simplify the constitution of a driving circuit by providing at least one of plural magnetic poles of a rotor with non-polar parts and also providing auxiliary magnetically sensitive elements for outputting a detection signal for an overlapping continuity angle by a plurality of magnetic poles and non-polar parts. CONSTITUTION:In a stator core 11, there are arranged stator coils 4r-4t making a 120 deg. electrical angle to each other and Hall ICs H1-H3 as main magnetically sensitive elements are arranged at a 120 deg. electrical angle. Further, a Hall IC H4 as an auxiliary magnetically sensitive element is arranged at the position making a certain electrical angle from said Hall IC H1. In a rotor 10, poles of permanent magnets are magnetized around a laminated core and recesses 13a-13d as non-polar parts are formed in respective intermediate parts of magnetic poles opposed to the Hall IC H4. The output of said Hall ICs H1-H4 is supplied to a switching circuit via a gate circuit not shown in the drawing.
