Generalized reluctances in eddy current magnetic circuits

Archiv für Elektrotechnik, 1964
The concept of generalized—complex or operational—reluctances is introduced. It is shown that these reluctances simplify considerably the calculation of systems, containing magnetic circuits with eddy currents. Two simple applications are worked out. Some results from a numerical study of the magnetic flux on breaking a telephone relay are given.

Coupled hydrodynamic lubrication and unbalanced magnetic force analysis in water-lubricated bearings for rim-driven thrusters

The Physics of Fluids
During the operation of rim-driven thrusters (RDTs), eccentricity between the journal and water-lubricated bearing (WLB), as well as between the motor's stator and rotor, is commonly observed.

Optimized-Sector-Based Model Predictive Torque Control With Sliding Mode Controller for Switched Reluctance Motor

IEEE transactions on energy conversion
In this article, an optimized-sector-based model predictive torque control (OSB-MPTC) strategy is proposed to reduce the torque ripple of the switched reluctance motors (SRMs).

Permanent Magnet Assisted Synchronous Reluctance Motor

2017
In these days, there is big emphasis put on electric motors efficiency, the best efficiency can be achieved with surface mounted permanent magnet (SMPM) motor. The SMPM motors efficiency may be even in cases of small machines, higher than 90%. Unfortunately this kind of motor is expensive, because neodymium magnets are used.
