Abstract

An analog trachometer signal is provided without the use of contacts, brushes, or complicated circuits. High performance DC tachometers suffer from high cost and limited brush life. Optical emitters do not provide reliable signals at low speed and are costly due to small tolerances and complicated circuits.
