This paper describes a control method in which microprocessors are used to implement all monitoring and control functions of a whole speed regulating system for commutatorless motors. A distinct feature of this speed regulator is that a power factor and an efficiency are optimized and an overload capacity is extended by employing a margin angle controller and an air gap flux controller.
The speed regulator using the microprocessor was tested with a 1 kW, 100 V, 4 pole commutatorless motor. Normal action in acceleration, constant speed and deceleration operations was confirmed. Rapid speed reversal with stable regenerative braking and smooth crossover operation were performed.
