Multi-harmonic tracking for diagnosis of rotor asymmetries in wound rotor induction motors
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013Most of the research work hitherto carried out in the induction motors fault diagnosis area has been focused on squirrel-cage motors in spite of the fact that wound-rotor motors are typically less robust, having a more delicate maintenance. Over recent years, wound-rotor machines have drawn an increasing attention in the fault diagnosis community due ...

Wound Rotor to Induction Motor and VFD Conversion Case Study
IEEE Transactions on Industry Applications, 2011This paper will present a method, which has been used to retrofit vintage wound rotor motors in various applications in the forest products industry. This calculation method was developed due to the end user's need to retrofit an existing application and the lack of detailed motor data.

A wound-rotor induction motor closed-loop control system
Proceedings of 1994 IEEE International Symposium on Industrial Electronics (ISIE'94), 2002A subsynchronous cascade system implemented in the laboratory permits motor speed control by using two cascade-connected governors (the first for speed and the second for current), to fire the inverter of the rotor DC link. A diode bridge is connected to the rotor terminals and the thyristorized inverter is connected to the line by means of an ...

On the Speed Control of Wound-Rotor Induction Motors Using Rotor Impedance Control
IEEE Transactions on Power Apparatus and Systems, 1979Significant improvements in the performance of rotor impedance control for constant speed operation of wound-rotor induction motors can be achieved by the introduction of an inductor as a third element of the series resistor-capacitor combination in the rotor circuit.

Dynamic performance of series-connected wound rotor induction motor
2010 IEEE International Conference on Power and Energy, 2010Series-connected induction motor has the ability of operation either at two speeds; the first one is less than the synchronous speed depending on the load, while the second speed is exactly double the synchronous speed. The motor has the capability of self-starting to reach the first speed.

Design Optimization of Wound Rotor Induction Motor Using Genetic Algorithm
2019 5th Conference on Knowledge Based Engineering and Innovation (KBEI), 2019Wound rotor induction motors have been underestimated for specific applications and high power. Therefore, in this paper, the optimization of the design of a wound rotor induction motor using a genetic algorithm with objective function including power losses and motor weight is proposed.

M.M.F.-harmonic effects in induction motors with phase-wound rotors
Proceedings of the Institution of Electrical Engineers, 1969While the influence of m.m.f. harmonics on the winding inductances of practical induction motors with phase-wound secondaries is extremely small, their effect on the current waveforms may be profound. The problem posed by this phenomenon is readily stated in terms of dynamic circuit theory, but the standard transformation techniques do not facilitate a

Stray Flux Analysis for the Detection of Rotor Failures in Wound Rotor Induction Motors
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019The analysis of the external magnetic field has been proven to be an effective way to diagnose different types of faults in induction motors. Classical methods based on permanent regime are being complemented by recent approaches that rely on the analysis of the magnetic field during transient operation of the machine.

Saliency and mutual inductance effect in cylindrical wound-rotor synchronous motor
2017 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2017In this paper the effects of saliency and cross-coupling in a cylindrical wound-rotor synchronous motor are evaluated within the operating region of the direct-axis, quadrature-axis and field excitations. In the calculation of the wound-rotor synchronous motor parameters, a finite element based approach (principle of frozen permeability) is followed to
