Journal ArticleDOI
Thermal Analysis of Radial-Flux Electrical Machines With a High Power Density
TL;DR: A lumped-parameter-based thermal analysis applicable to radial-flux electrical machines with a high power density is presented and the performance of the developed thermal model was verified by comparing the calculated temperature values with the measurements in three different applications.
Journal ArticleDOI
Direct-drive permanent magnet generators for high-power wind turbines: benefits and limiting factors
R. Scott Semken,Maria Polikarpova,Pekka Röyttä,J. Alexandrova,Juha Pyrhonen,Janne Nerg,Aki Mikkola,Jari Backman +7 more
TL;DR: In this article, the authors review the technological and economic benefits and limitations of direct-drive permanent magnet synchronous generators (DD-PMSGs) and consider their appropriateness as a key piece in the overall wind turbine system design.
Journal ArticleDOI
Multidisciplinary Design Process of a 6-Slot 2-Pole High-Speed Permanent-Magnet Synchronous Machine
TL;DR: The design process described in this paper provides a straightforward procedure for the multidisciplinary design of HS permanent magnet electrical machines.
Journal ArticleDOI
Direct-Driven Interior Magnet Permanent-Magnet Synchronous Motors for a Full Electric Sports Car
TL;DR: The design process of direct-driven permanent-magnet (PM) synchronous machines (PMSMs) for a full electric 4 × 4 sports car is presented and an integer slot stator winding was selected to fully take advantage of the additional reluctance torque.
Journal ArticleDOI
High-Speed High-Output Solid-Rotor Induction-Motor Technology for Gas Compression
TL;DR: In this paper, solid-rotor material selection, rotor slitting, and the end effects of the purely solid rotor are discussed, and a frequency-dependent end-effect correction factor is introduced and a method for the rotor-end-leakage correction is presented.
