Rotating signal generator apparatus.

摘要

A signal whose frequency is proportional to a rotational speed of a rotor (110) and whose rising and falling angles near points crossing zero becomes larger with the rotational speed of the rotor is used to produce a first signal (V1) of amplitude corresponding to the rising and falling angles and a second signal (V2) of amplitude corresponding to the frequency, a difference between the first and second signals is evaluated, and the first and second signals (V1, V2) are corrected with the difference.
