Abstract
Tooth-ripple losses in the rotor poles of a synchronous machine can be measured directly by measuring an alternative Poynting vector, in the rotor reference frame, from the electric and magnetic fields in the air gap of the machine. The total field in the air gap can be analyzed into a number of travelling waves. The induced effects due to each wave are observed at a different frequency in the rotor. This enables the measurement of the power loss due to each individual harmonic in an actual machine while all the harmonics are simultaneously present.
