Analog dc tachogenerators are widely used as velocity transducers in industrial control systems. Despite the widespread use of miniature dc generators for this purpose, there are practical alternatives that should be considered for the analog measurement of velocity. The design and performance characteristics of homopolar and derived tachogenerators are discussed. These transducers are unique in their low inertia and noise generation, making them particularly suitable for velocity-control systems using high-performance dc motors as the power actuators.
