AN ANALYSIS OF STEP SERVO MOTOR PERFORMANCE
Abstract:
The step servo motor is designed to convert a discrete input into a continuous output. Recent advances in miniaturization techniques have permitted the production of stepper motors capable of following program rates on the order of 100 steps per second. This paper presents an experimental analysis of step servo motor performance, demonstrates that stepper motor transient responses may be predicted with reasonable accuracy using linear, second order theory, and indicates maximum stepping rate capabilities of the Size 11 Stepper Motor for several different programs. Additionally, it is shown that for the Size 11 Stepper Motor, inability to successfully follow a programmed input is attributable primarily to rotor inertia.
