Electric motors consume over half of the electrical energy produced by power stations, almost the three-quarters of the electrical consumption in industry and almost the half of commercial electrical consumption in developed countries. Motors are by far th ...
This paper presents a combined analytical and finite-element (FE) method for computation of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar ...
An unbalanced DC-link voltage regulation strategy is proposed for a three-level voltage source inverter used in the rotor cascade of a double-fed asynchronous motor-generator. The major problem in determining the presence of the unbalanced component is inv ...
In recent years the use of solid state frequency converters is rapidly increasing in the industrial and power plants where electric machines are installed, since it allows variable speed operations for the electric system, thus becoming a key factor which ...
A combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient pole synchronous generators is presented in this article. Very precise prediction of the no-load voltage, including saturation effects as well as the e ...
The aim of this project is the design and the optimization of the electrical motors used in the Continuously Variable Transmission (CVT) system currently under development at JTEKT, an automotive part supplier company. Two motors are needed for the control ...
Sensorless control of PMSM's (Permanent Magnet Synchronous Motors) has occupied scientists for a long time. The result of this research is becoming widely accepted by the industry due to its low cost and reliability. However, the majority of today's motor ...
This paper presents a combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar currents due to t ...
Recent research has shown that it is possible to independently control two three-phase induction machines while supplying them via a single five-leg voltage source inverter (VSI). In such a two-motor drive system one phase of each motor is connected to a c ...
In order to create a new solar aircraft totally powered by the sun, a new method able to handle such a complex system must be developed. The project aim is to make a round-the-world flight in so as to promote the sustainable development. The aircraft power ...
