Investigation of Permanent Magnet Machines for Downhole Applications: _ Design, Prototype and Testing of a Flux-Switching Permanent Magnet Machine
(Doctoral Theses at NTNU, 1503-8181; 2011:23, Doctoral thesis, 2011)The current standard electrical downhole machine is the induction machine which is relatively inefficient. Permanent magnet (PM) machines, having higher efficiencies, higher torque densities and smaller volumes, have widely ...
