New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]
, 2014 For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase

Unsteady wake modelling for tidal current turbines
, 2011 The authors present a numerical model for three-dimensional unsteady wake calculations for tidal turbines. Since wakes are characterised by the shedding of a vortex sheet from the rotor blades, the model is based on the vorticity transport equations.
