The rotor losses in a synchronous machine with a slotted solid rotor were derived from transient temperature rise curves. The losses induced by the armature teeth and the additional losses caused by harmonic fields associated with the space non sinusoidal distribution and the harmonic components of phase currents were deduced from the values with different loads. The saturation of the rotor involved an increase of the teeth harmonic losses and a decrease of the additional losses. The magnetic field harmonic components measured in the air-gap agree with the losses analysis. In this work, the influence of the field distribution in space is particularly discussed. Some measurements were carried out with damper windings. The results show its in...
