Abstract: A control apparatus for a motor having a rotor includes a resolver, a processor, a decoder, a sensor, and a motor driver. The resolver outputs waveforms sensed from a rotation of the rotor. The decoder generates an absolute angle signal and an incremental angle signal in response to the waveforms from the resolver and provides the absolute angle signal and the incremental angle signal to the processor.
