Rotor Eddy-Current loss in permanent-magnet brushless AC machines [PDF]
IEEE Transactions on Magnetics, 2010 This paper analyzes rotor eddy-current loss in permanent-magnet brushless ac machines. It is shown that analytical or finite-element techniques published in literature for predicting rotor eddy-current loss using space harmonic based approaches may not ...

Effect of optimal torque control on rotor loss of fault-tolerant permanent-magnet brushless machines [PDF]
, 2002 A faulted phase in a fault-tolerant permanent-magnet brushless machine can result in significant torque ripple. However, this can be minimized by using an appropriate optimal torque control strategy.

A Novel Sleeve Design to Reduce the Eddy Current Loss of High-Speed Electrical Machines
Machines, 2023 Demand for high-speed motors is increasing. Surface-mounted permanent magnet synchronous motors (SPMSM) used in high-speed applications have magnets attached to the rotor, so there is a risk of damage and scattering due to centrifugal force as the speed ...
