Rotor Surface Ferrite Permanent Magnets in Electrical Machines: Advantages and Limitations
IEEE Transactions on Industrial Electronics, 2017Permanent-magnet synchronous machines (PMSM) are gaining a foothold in a growing number of applications. However, the high cost of these machines compared with the prices of induction motors, whose production process is mature and material costs are low, limits the use of PMSMs with rare-earth permanent magnets in many potential cases.

Superconducting wound rotor for axially excited electrical motor
Journal of Physics and Chemistry of Solids, 2006The development of HTS motors of the fractional range has shown the relevance of the design of the rotor where the opportunity to apply HTS in both BSCCO tapes and YBCO bulks has been demonstrated as an efficient way to increase the power density. In this work we report on a BSCCO wound rotor axially excited showing the advantages over equivalent ...

Measurement of electrical polar symmetry in turbogenerator rotors
Measurement Science and Technology, 2012This paper presents a measurement technique and an analysis of the electrical polar symmetry in turbogenerator rotors using the so-called recurrent pulse comparison with the injection of charge as the excitation source. The polar symmetry should be measured because it provides information that allows electrical insulation failures in the rotor winding ...

Electrical instability in cardiac muscle: Phase singularities and rotors
Journal of Theoretical Biology, 1989A dynamical system is "excitable" at some stage in its behavior (e.g. at a rest state or while it is nearly at rest prior to a spontaneous event) if a small, but not too small, stimulus of the right kind elicits an immediate big reaction that eventually leads back to the original state.
