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 ...
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 ...
The paper presents a simplified analytical method to design a small two-pole slotless brushless dc motor. Using only a few approximations, the motor analytical model is formulated to generate a system of equations. The system can be solved analytically, pr ...
Worldwide high speed Maglev (> 400km/h) developments refer to Maglev such as the Japanese JR-Maglev MLX, the German Transrapid and the USA Inductrack Maglev. Other world projects exist such as the Japan HSST (< 300km/h) and the China HTC. The JR-Maglev, th ...
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 ...
The current source thyristor inverter is still today a suitable choice for supplying high power adjustable speed drives for pumps or compressors. This paper presents a 12-pulse LCI (load commutated inverter) synchronous drive for a 20 MW compressor, it foc ...
The present paper deals with the determination of voltage stresses on PWM inverter fed induction motors by considering first the cable modeling and the measurement of different parameters. Then, based on this model, voltage stresses on the motor windings a ...
Power-electronic inverters are becoming popular for various industrial drives applications. In recent years also high-power and medium-voltage drive applications have been installed. However, the existing solutions suffer from some important drawbacks. Hyb ...
This publication presents the application of Non-Linear Programming (NLP) to the design of AC induction motors driving hydraulic pumps on commercial aircrafts. In addition to the usual constraints on the geometry or on the efficiency of the motor, the spec ...
Developments trends in commercial drives point that that the next generation of them includes some sort of sensorless torque control. Using the 'spare' processing power of a digital signal processor (DSP) to implement these techniques can significantly red ...
