Magnetic Equivalent Circuit applied to a unipolar PMSM

The XIX International Conference on Electrical Machines - ICEM 2010, 2010
Design and development of electrical machines require a good accuracy model with a low time process. Compared to finite element analysis and analytical model magnetic Equivalent Circuit (MEC) presents compromise between time process and accuracy. This paper presents two MEC method used to modeling a unipolar permanent magnet synchronous machine (PMSM) (

Equivalent Circuit of AC Magnetic Fields

2019
An effective equivalent circuit method suitable for high-frequency usage is explained in this chapter. This equivalent circuit is based on the ladder network originally proposed by Wilhelm Cauer (1900–1945) in the field of network synthesis. This method enables significant reduction of computations and also enables coupled analysis of magnetic field ...

Interior type permanent magnet synchronous motor analysis by equivalent circuits

IEEE Transactions on Energy Conversion, 1989
Experimental tests show that steady-state core loss of interior-type permanent magnet machines changes with the terminal voltage in a peculiar way due to flux redistribution produced by armature reaction. An equivalent circuit is proposed to predict such loss through new parameters that can be easily determined by experimental tests.

Equivalent circuit for coil-patient interactions in magnetic resonance imaging

Magnetic Resonance Imaging, 1987
An equivalent circuit is presented which accurately models the performance of magnetic resonance imaging receiver coils used with conducting samples. Coil-sample interaction is determined by measuring either the complex impedance or the associated resonant frequency and quality factor when samples of different conductivity are placed in the coil.

Magnetic equivalent circuit model of a hybrid excitation synchronous machine

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2008
PurposeThe purpose of this paper is to present an analytical modeling based on lumped parameter magnetic circuits of a hybrid excitation synchronous machine. The model is first established and compared with 3D finite elements analysis and measurements.

Temperature Dependent Equivalent Circuit of a Magnetic-Shield Type SFCL

IEEE Transactions on Appiled Superconductivity, 2005
In order to investigate the reciprocal interaction between a SFCL and the Power System an equivalent circuit of the device needs to be introduced in a power system simulator. In this paper the equivalent circuit of a magnetic shield type SFCL, consisting of two coupled electric and thermal networks, is obtained starting from the integral formulation of

The derived equivalent circuit model for non-magnetized and magnetized graphene

2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES), 2016
In this work, for the first time the electromagnetic features of graphene are characterized by a circuit model derived instead of fitted from the electric field integral equation (EFIE). The atomically thick graphene is equivalently replaced by an impedance surface. When it is magnetized, the impedance surface is anisotropic with a tensor conductivity.

Magnetic-Equivalent-Circuit-Based Scaling Laws for Low-Frequency Magnetic Devices

IEEE Transactions on Energy Conversion, 2013
This paper sets forth a method to obtain scaling laws for low-frequency power magnetic devices using normalized magnetic equivalent circuits. The resulting scaling laws are meant to facilitate the system-level design. While the method is presented in general, it is demonstrated using an inductor as an example.
