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 ...
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 ...
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 ...
Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...
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 ...
Usually, each phase of the direct reluctance motor is fed separately by its own inverter producing a squarewave phase current depending on the rotor position. In the present work, a star-connection of the three stator phases is used and the direct reluctan ...
NOVELTY - After disconnection from normal control (3) a pulse generator (4) sends positive and negative pulses to a motor winding R. The response currents are measured (5) from voltages (Vpr,Vnr) which appear after a fixed time on a neutral resistor (2) an ...
The present paper presents an automatic approach for the determination of the parameters of laminated salient-pole synchronous machines, based on 2D finite element method (FEM). Calculations using FEM are performed in rotation (sudden three-phase short-cir ...
Extended Kalman filtering techniques have been successfully used as sensorless control schemes on many different types of synchronous motors. One big disadvantage of the extended Kalman filtering technique is the large computational cost. Even with today's ...
