Abstract
PURPOSE: To obtain magnetic position detection signals of which accuracy is high and of which detection lag is small using simple circuit configuration.
CONSTITUTION: Before leading the output signals generated at the output windings of the angle of rotation detector 12 using a resolver or synchronous transmitter into the respective dividers 16a and 16b, the respective multiplicators 22a and 22b are mounted and the output signals from the transmitter 10 are multiplied. The output signals obtained of the multiplicators are led into the respective dividers 16a and 16b and divided by the square-law signals of oscillator output in these dividers. This permits magnetic pole position detection signals with high accuracy and hardly small phase lag to be obtained using one-sided polarity dividers.
