WHEN A BRUSHLESS D.C. MOTOR (3, 13) IS DRIVEN BY VOLTAGE4ED INVERTERS (2, 5, 12, 20), A CONDUCTING INTERVAL OF THE VOLTAGE-FED INVERTERS (2, 5, 12, 20) IS DETERMINED TO BE GREATER THAN 120° AND EQUAL OR LESS THAN 180° B.Y ELECTRICAL ANGLE SO THAT IMPROVEMENT IN EFFICIENCY AND ENLARGEMENT IN OPERATING RANGE OF THE BRUSHLESS D.C. MOTOR IS ACHIEVED WITH SIMPLE AND CHEAP CONTROLLING. (FIGURE 4)
