Determination of the temperature rise as well as the power dissipated inside induction machines as heat is a matter of interest to both customers and manufacturers. This is important since it affects the insulation materials, the cooling systems and the efficiency of the machine. In this paper, some of established methods of full-load temperature rise testing of induction machines, such as direct loading test, back-to-back test, phantom loading test, forward short circuit test, variable inertia test and mixed-frequency test, have been reviewed. The experimental and simulation results of the mixed-frequency test using an inverter have been analysed in detail.
