Influence of the amount of permanent-magnet material in fractional-slot permanent-magnet synchronous machines [PDF]

open access: yes, 2014
The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful

Quasi-flat linear PM generator optimization using simulated annealing algorithm for WEC in Indonesia

open access: yesJournal of Mechatronics, Electrical Power, and Vehicular Technology, 2019
Linear permanent magnet generator (LPMG) is an essential component in recent wave energy converter (WEC) which exploits wave’s heave motion. It could be classified into tubular-type, flat-tricore type, and quasi-flat type.

Low secondary electron yield engineered surface for electron cloud mitigation [PDF]

open access: yes, 2014
Secondary electron yield (SEY or δ) limits the performance of a number of devices. Particularly, in high-energy charged particle accelerators, the beam-induced electron multipacting is one of the main sources of electron cloud (e-cloud) build up on the ...

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

open access: yes, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...
