<P>PROBLEM TO BE SOLVED: To miniaturize a motor drive controller and to reduce costs. <P>SOLUTION: A brushless motor 20 is equipped with hall IC's 28u-28w. A microcomputer 51 is provided for forming an electrification signal on the basis of position detecting signals from these hall IC's 28u-28w and preset voltage and phase commands. An AC power source 36 is equipped with a DC power source circuit 40 and on the output side thereof, an electrification means 49 is provided for electrifying winding wires 23u-23w on the basis of the electrification signal formed by the microcomputer 51. The microcomputer 51 regulates the phase command or voltage command of the electrification signal for brake on the basis of the voltage detected result of a voltage detecting circuit 50. <P>COPYRIGHT: (C)2003,JPO |
