Abstract
A portable test device (1) can be configured as a rotor conductivity anomaly tester, a magnetic core anomaly tester, or a rotational eccentricity fault tester for a multiphasic motive force electrical machine (6) by providing an immotive multiphasic motive force electrical machine test signal from a plurality of multiphasic motive force electrical machine signal generators (4) through a detachable electrical power connectivity (2) and by having a multiphasic motive force electrical machine fault analyzer (16) that can sense responses and discern the existence of a fault. Control of the test signal can be accomplished by an immotive multiphasic test signal controller (3) that varies frequency and achieves incremental movement or to achieve stator magnetization plane angle changes or movement that tests angular relationships.
