For rotordynamic analysis of hydropower units, the generator is treated as a rotating rigid body. However, previous studies have confirmed that certain designs generators are elastic, so complex geometry cannot be considered rigid. This work produced model with floating rotor rims, consisting hub and flexible rim coupled connections. The takes into account influence centrifugal Coriolis effects...

This paper describes a new method for indirect sensing of the rotor position in switched reluctance motors (SRM’s) using pulsewidth modulation voltage control. The detection method uses the change of the derivative of the phase current to detect the position where a rotor pole and stator pole start to overlap, giving one position update per energy conversion. As no a priori knowledge of motor p...
