<P>PROBLEM TO BE SOLVED: To provide a control device of a three-phase brushless motor which prevents stop due to a transitional load variation, with more reliability. <P>SOLUTION: The control device of the three-phase brushless motor includes: a three-phase bridge inverter circuit (15) which supplies a drive voltage to each phase of the three-phase brushless motor (37); and a complementary intermittent energization drive means (32) which applies a PWM signal smaller than 180° in conductive angle to a transistor of the inverter circuit (15), and drives the three-phase brushless motor by a complementary intermittent energization drive system. <P>COPYRIGHT: (C)2011,JPO&INPIT |
