Measurement Accuracy Requirements for the Efficiency Classification of Converters and Motors
(IEEE, 2019-11-28)
Electrical machines play a major role in the electrical energy consumption in the modern world; therefore, the efficiency of electrical machines has been regulated for a long time by different authorities. Recently, the ...
Experimental Investigation of a 75 kW Induction Motor Drive System Losses and Efficiency
(IEEE, 2019-12-09)
The frequency converter driven IM can be used as a reference for the efficiency level of a drive system. In here, the losses and efficiency of a 75 kW IE3 -rated modern squirrel-cage induction motor are investigated ...
Analytical Evaluation of High-Efficiency Induction Motor Losses
(IEEE, 2019-08-05)
An analytical motor design-based approach is used to evaluate the major loss components of a premium-efficiency (IE3)four-pole squirrel-cage induction machine. In the analytical approach, the geometry of the machine and ...
Determination of High-Frequency Harmonic Power in Converter-Fed Motors
(IEEE, 2022-10-13)
This paper focuses on usage of frequency domain power analysis on harmonic power extraction in converter-fed motor measurements. Synchronous generator and frequency converter supplies are compared in 16 operating points ...
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 ...
Loadability of Converter-fed Induction Machine
(IEEE, 2023-10-02)
The main dimensioning principle of an electrical machine is the temperature rise that is directly related to losses of the machine. When PWM–supply is used, an additional high frequency switching frequency dependent loss ...
