Abstract :
To measure accurately the instantaneous angular velocity of a low-inertia stepper motor, a simple noncontact capacitance transducer has been developed. The capacitance has a value linear1 related to angular displacement of the motor shaft. The basic design is discussed, and construction details and practical result are give.
