step response Motor-shaft rotational response of a stepper motor to a step command related to time.
step-servo motor A device that, when properly energized by dc voltage, indexes in definite angular increments.
steps per revolution The total number of steps required for the output shaft of a dc stepping motor to rotate 360°, or one complete revolution. Steps per revolution is calculated by dividing the step angle into 360°.
steps per second The number of angular movements accomplished by the motor of a dc stepping motor in 1 second. This figure replaces the rpm figure of a standard drive motor.
step stress test A test consisting of several stress levels applied sequentially for periods of equal duration to a sample; during each period a stated ...
