Wang, X. (author), Liu, D. (author), Lahaye, D.J.P. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)The brushless doubly-fed induction machine (DFIM) has great potential as a variable-speed generator for wind turbine applications. This special machine has a richer space-harmonic spectrum due to its special nested-loop rotor construction compared with conventional induction machines. It may result in higher iron losses, higher torque ripple and...conference paper 2017

Wang, X. (author), Liu, D. (author), Lahaye, D.J.P. (author), Polinder, H. (author), Ferreira, Jan Abraham (author)Permanent-magnet machines with fractional slot concentrated windings are easy to manufacture. Their popularity therefore is steadily increasing. Without a proper design, however, the induced eddy-current losses in the solid rotor get rather high. The modeling and the prediction of eddy-current losses for these machines are thus very important...conference paper 2016
