Analysis and Design of Novel High Speed Permanent Magnet Machine Considering Magnet Eddy Current Loss

open access: yesIEEE Access, 2020
In high speed permanent magnet (HSPM) machines, the computation of magnet eddy current loss is essential as these losses significantly affect the temperature of the permanent magnet (PM) and electromagnetic performance and can result in irreversible ...

Copper loss analysis and loss separation method in a dynamic process of ultra‐high speed motor with slotless stator

open access: yesIET Electric Power Applications, 2023
Different from the copper loss of general permanent magnet (PM) motors, the copper loss of ultra‐high‐speed permanent magnet motors (UHSPMSM) includes DC losses and eddy current losses, which lead to difficulty in analysis.

Interior Permanent Magnet Synchronous Motor Design for Eddy Current Loss Reduction in Permanent Magnets to Prevent Irreversible Demagnetization

open access: yesEnergies, 2020
We designed and analyzed an interior permanent magnet synchronous motor (IPMSM) to prevent irreversible demagnetization of the permanent magnets (PMs). Irreversible demagnetization of NdFeB PMs mainly occurs due to high temperature, which should thus be ...

A Novel Sleeve Design to Reduce the Eddy Current Loss of High-Speed Electrical Machines

open access: yesMachines, 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 ...
