Field-circuit models of the BLDC motor were developed taking into account rotational speed control by two classic methods: the unipolar H_ON_L_PWM and the bipolar H_PWM_L_PWM. Waveforms of the electrical and mechanical quantities and the motor parameters were computed. The results of the computations were verified by measurements performed on a specially designed test stand. On the basis of the measuredwaveforms of the electrical and mechanical quantities the dependence of the drive system efficiencies and power losses on rotational speed was determined for the two methods of inverter control.}, type={Artykuły / Articles}, title={Analysis of the influence of inverter PWM speed control methods on the operation of a BLDC motor}, URL={http://czasopisma.pan.pl/Content/108894/PDF/art17.pdf}, doi={10.24425/aee.2018.124834}, keywords={analysis, brushless DC motors, electrical machines, PWM speed control, measurements}, }
