Abstract:
A rotation-position detection system according to the present invention is configured with a resolver mounted in a brushless motor and a motor controller. The motor controller outputs an excitation signal to the resolver and an A/D converter thereof alternately applies analogue/digital conversion to a sine wave signal and a cosine wave signal outputted from the resolver so that a rotation position of the motor is calculated.
