Abstract
The present invention relates to a resolver excitation signal generating apparatus for supplying a reference excitation signal to a resolver attached to a motor for driving a robot or a computer numerical control machine. When a sine-wave signal is transferred from a signal generator to the resolver, the signal is filtered by a low pass filter, amplified up to the rated voltage by means of a line driver and supplied to the resolver, thereby allowing the position of the motor to be controlled exactly.
