Abstract
Certain design considerations, construction detail, and performance data are presented for a small disk-type homopolar tachometer which was developed as a low inertia, low noise, low friction rate signal source for incorporation into a high-performance servomechanism. Performance characteristics reveal that a unit of this type has certain advantageous features which recommend it over conventional tachometers, although a low signal output level is an inherent disadvantage.
