Abstract
In order to improve the rotate-speed precision of micro-turbojet engine and reduce costs of measuring equipment, a rotational speed measurement system based on STC89C52 and using Hall Sensor was researched. A simulative working process, based on the model of micro-turbojet engine and using DC motor to drive spindle, was studied. A relatively better result was gotten by using this system and equipment. Compared with other methods, the circuits is simpler with higher precision and stronger capability of resisting disturbance, especially when the speed range is great.
