Electric drives consume a great amount of the world's energy, and it will keep increasing due
to the electromobility trend. Thus, the efficiency of electric drives must be improved to reach …

This article presents and validates a method for early estimation of the high-frequency
impedance response for a real permanent magnet synchronous machine. The main …

With the widespread use of inverters with increasing switching frequencies in three-phase
AC machines, parasitic and harmful bearing currents with high frequencies may occur. To …

In this article, a high-frequency (HF) six-port delta-and star-connected three-phase induction
motor model is proposed. The model consists of multistage RLC circuits, which include the …

Electric machines for electric aircraft propulsion applications must be designed to deliver
high levels of propulsive power under low air pressure conditions with maximum power …

This paper presents a method for predicting high-frequency behavior of rotating electrical
machines. An approach using the Finite Elements (FE) method coupled with a circuit …

Asynchronous loads (AL), because of their low negative-sequence resistance, produce the
effect of reduced unbalance at their connection points. Therefore, proper modeling of …

A universal grey box model is proposed to model permanent magnet synchronous machines
(PMSM) with interior magnets for a wide frequency range. The proposed model supports the …

This paper presents parametric models for high-frequency common-and differential-mode
impedance analysis of electrical machines. The models are presented in terms of lumped …

A coil-based grey box model is developed for high-frequency modeling of permanent
magnet synchronous machines (PMSMs) with interior magnets in rotors to predict the …
