Abstract

PURPOSE: To achieve the improvement in noise resistance and measurement accuracy by sending out the output voltage of a rotor coil after amplifying the same with the driver in resolver part without directly sending the same to a digital converter parts.
CONSTITUTION: A DC voltage generating circuit 25 is provided as the operating power source of a comparator 19 and driver 24 in a resolver part 12. The output voltage of a rotor coil 17 is not directly sent to a digital converter part 11 and is sent out after having been zero detected through the comparator 19 in the resolver part 12 and having been sufficiently amplified with the driver 24. This considerably improves noise resistance to external noise. Hence, even if the distance between the resolver part 12 and digital converter part 11 is taken long, the rotating angles of machine shafts may be detected by applying the stop position signal to a counter controller 21 with sufficient accuracy.
