Basic development of one-chip control circuitry for commutatorless dc motors
Abstract
A monolithic one chip circuitry including the detection of rotor speed control and the direct load current drive of dc-motors with an electronic commutation was developed because of the increased efficiency of commutatorless dc-motors in which high-quality magnetic materials were used. The hardware demonstration of Hall-Sensor-elements in a power compatible technology was successful. A design based on the data is shown.
