5 kW high-efficiency induction motor is analyzed using 2D open-source platform and the results are compared with commercial software and measurements. The importance of equivalent circuit parameters in 2D analyses is ...
Design and Manufacturing of a Modular Low-Voltage Multi-Megawatt High-Speed Solid-Rotor Induction Motor
(IEEE, 2021-05-26)
High-speed solid-rotor induction machines (HSIMs) are popular within high-speed applications because of their high rotor structural integrity and their fairly well-established manufacturing process guaranteeing high quality ...
Comparison of Synchronous Reluctance Motors and Permanent Magnet Synchronous Motors with Direct Liquid Cooling Arrangement
(IEEE, 2023-09-06)
A comparison of Synchronous Reluctance Motors and Permanent Magnet Synchronous Motors with a Direct Liquid Cooling system is given. Both solutions have been analyzed, designed, and optimized considering the same constraints ...
Irreversible demagnetization risk of rotor-surface-mounted permanent magnets at rated and short-circuit modes in two-pole multi-megawatt machines
(IEEE, 2023-09-12)
The flux density distribution of a rotor-surface-magnet two-pole 4 MW permanent-magnet synchronous machine with a solid rotor core is studied in three different operating modes: rated operation, two- and three-phase short ...
Energy Efficiency Analysis of Electric Vehicle System Components
(IEEE, 2024-01-02)
There are several figures used to promote the energy efficiency of battery electric vehicles (BEVs). A critical analysis of the energy consumption of BEV systems is presented here. A typical approach to estimate the ...
