Electrical Machine Rotor Shielding for Low Cost Electrical Drive [PDF]
2018 IEEE Transportation Electrification Conference and Expo (ITEC), 2018 Electrical machine rotor shielding has been proposed for high-speed electrical machines, i.e., ≥50krpm, where a smooth current waveform becomes difficult and costly to generate due to the required high switching frequency. The rotor shielding is used to suppress the unsynchronized low order high amplitude current harmonics and consequently reduces the ...

Sensorless Modeling of Varying Pulse Width Modulator Resolutions in Three-Phase Induction Motors. [PDF]
PLoS ONE, 2017 A sensorless algorithm was developed to predict rotor speeds in an electric three-phase induction motor. This sensorless model requires a measurement of the stator currents and voltages, and the rotor speed is predicted accurately without any mechanical ...
