The research object is a DC machine transforming mechanical energy into electric, i.e. a DC generator. The authors describe the work of the machine in terms of external and regulatory characteristics and characteristics of idle run. The research purpose is to study the influence of an accumulator battery in an electric circuit of a generator on dynamic characteristics. Since at idle a generator is out of circuit, the load rate is zero, and the current in its series winding is 2-3 A. Therefore, we can exclude polarization voltage influence on measurement devices. Experimental tests of the dynamics of a voltage regulating system of a DC generator help conclude that under certain conditions, the system becomes unstable. While analyzing the dynamics of a voltage regulating system of a DC generator with accumulator battery, the authors find out that instead of a common consideration of a controlled object as a link with one excitation time constant T1, it’s necessary to consider the controlled object as a second-order link. Connection of inertial voltage regulator fundamentally changes the issue of stability of a system under certain conditions. In this case, a high transfer ration of an inertial regulator is a certain prerequisite. This nuance can destabilize the controlling system.
