A coupled system simulator, based on analytical circuit equations and a finite element method (FEM) model of the motor, is used to analyze a direct-torque-controlled (DTC) frequency-converter-fed industrial 200 kW squirrel-cage induction motor. The measured stator voltage waveforms are used as inputs to the FEM motor model, and the results are compared with the measured ones. Comparison is also made...
In this paper we present a novel modelling method of the permanent magnet motor. This method depends on the combination of the singular value decomposition (SVD) on the mathematical framework and the energy function method on the physical framework. We take the SVD-based macromodel approach to derive the static characteristics of the motor using only the co-energy. The co-energy is calculated as a...
This paper presents a combined contactless energy and data transmission system, which is able to detect and to identify a secondary device and which is also able to check its absolute position during the energy transfer. Such an identification is needed in many fields of application under aspects like safety and security. Compared to conventional industrial communication systems like Bluetooth or...
In this work is presenting a reactive homopolar synchronous machine with stator excitation (RHSMSE) destined to operate as generator of low and middle power or as servomotor with reduced inertia and high-speed. We proposed in this paper a modeling and a simulation method by electric-magnetic coupled network, based on the permeance network and 3D FEM analysis with specialized software. In this paper...
