To the calculation of higher harmonic moments in asynchronous motors.
Abstract
The formulas for calculating the moments of higher harmonics in asynchronous short-circuited electric motors taking into account the moments due to transverse currents are derived. The proposed correlation for calculating the maximum values of moments. The resulting formulas can be used to calculate the moments caused by both the harmonic components of the ppm and the harmonics caused by the unevenness of the air gap. Comparison of calculated and experimental data is carried out on the example of the AO2-71-4 electric motor. Ill. 2, Bible. 4.
