The map tells us that the motor is more efficient (on a 0-100 scale) when the speed is lower than 4,000rpm and the torque is lower than 250 NM. An induction machine presents a different efficiency map topology: The efficiency remains high even at high speed and high torque compared to an IPM machine. However, the induction machine is less ...

The 2P and 4P harmonics of the torque supplied by a two blade vertical axis wind turbine propagates in the drive train of the wind turbine and deteriorates the quality of the electric power transmitted to the network. This paper shows how the torque ripple propagates and how it can be eliminated by electrical instead of mechanical means. This elimination is obtained by using a converter-fed ...
