Interpolation and analysis of the efficiency of a synchronous reluctance electric drive at various load points of a fan profile

The article considers the problems of calculation and interpolation of the efficiency of a synchronous reluctance fan drive in a wide range of loads. In order to estimate the performance of the fan, a semi-analytical model on the basis of experimental data on the selected operating modes is used. The errors of various approaches for interpolating the data on the efficiency of a variable frequency drive using a limited amount of experimental data is estimated.
