ABSTRACT:
An amplitude normalization circuit13finds the amplitude of position signals outputted from a position detection circuit6on the basis of Hall signals from Hall elements2ato2c. The position signals from the position detection circuit6are then divided by the thus found amplitude and are thereby normalized. Multiplier circuits7ato7cthen multiply by a torque error signal limited by a limiter5the position signals normalized by the amplitude normalization circuit13to generate pseudo-sinusoidal signals.
