Abstract
A method of operating a resolver management device according to the present invention includes: generating an excitation signal by using an external control signal; counting a time interval (a first delay time) to a first pole of the excitation signal based on one period of the external control signal by using an internal clock; receiving an excitation signal reflected from a resolver sensor; counting a time interval (a second delay time) to a second pole of the reflected excitation signal at the first pole by using the internal clock; and transmitting a first count value corresponding to the first delay time and a second count value corresponding to the second delay time to a microcontroller unit (MCU).
