<p>A method and an apparatus using the method that generates an index pulse which includes firstly the generation of a first electronic signal which includes a first level and a second level based upon a multiphase sinusoidal motor control circuit (34). Secondly, the generation of at least a second electronic signal that includes a first level and a second level based upon a multiphase sinusoidal motor control circuit (34) wherein the first electronic signal and the second electronic signal are levelly spaced apart based upon the phase number of the multiphase sinusoidal motor control circuit wherein a set difference in level exists for a first specified period between the first and said signal. Thirdly, the determination of the index pulse based upon a transition from the first level to the second level of the first electronic signal.</p> |
