By the measurement of the temperatures in different points of the machine (rotor, stator, coils and magnetic circuit of the stator) and to a simplified thermal model of the motor, the value and the localization of the losses for each type of supply can be deduced. The method consists of determining the distribution of the losses so that the theoretical heating curves obtained from the thermal model coincide with the experimental heating curves. Some parameters used for the elaboration of the then.-al model are poorly known, therefore, we determine them by simple tests of the motor for which the distribution of the losses is well known. Then, we test our method in the case of a sinusoidal supply and we exhibit the extra losses in the rotor, which are difficult to identify with another method. After that, we can study the distribution of the different losses in the motor when it is supplied by an inverter |
