Abstract
This paper describes a method of measuring the comparatively short response time of DC motor. It is measured by the means that the number of half-cycle period from the moment when the step input is applied to this armature terminal to achieve the point of intensity modulation which is set up on the firing angle of magnetic amplifier, and the number of half-cycle period can be looked directly on the cathode-ray oscilloscope as the repeated transient phenomenon.
The transient response is investigated analytically, in case of the step input of DC voltage is applied to the armature terminals, and an analysis is extended to the method of measuring the response time in case of the ripple of 50c/s or more higher (sinusoidal) frequency is superposed on this transient response.
