Eddy-current loss in the rotor magnets of permanent-magnet brushless machines having a fractional number of slots per pole [PDF]
, 2005 We develop an analytical model for predicting the eddy-current loss in the rotor magnets of permanent-magnet brushless machines that have a fractional number of slots per pole, when either all the teeth or only alternate teeth are wound, and in which the

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 ...
