When a voltage comprising a fundamental and a second harmonic of appropriate magnitude is applied to an induction motor which has no coupled load, approximately full-load conditions can be simulated, thus enabling the motor temperature rise to be determined. Circuit arrangements for the proposed test method and experimental results are presented.
