Electrical motors and drives are the driving force in industry and economy. Continuous improvement of their efficiency is critical to reduce CO2 emissions; however, accurate measurement of their power losses poses a particular challenge. At present, it relies on input-output methods to test permanent magnetic (PM) machine drives and power electronics, which proved to lack precision for highly efficient...
The determination of the power losses in the high-efficiency electric motors with distorted voltage and current waveforms is technically challenging and thus an alternative using the calorimetric measurement systems is gaining in popularity. Different types of calorimetric systems with their pros and cons have been proposed in the literature but they are generally limited in measurement accuracy and...
