Losseless Starting Method For The Wound Rotor Induction Motor

ECMS 2012 Proceedings edited by: K. G. Troitzsch, M. Moehring, U. Lotzmann, 2012
In heavy duty drives in the range of hundreds kW, like cement and minerals industries, wound rotor induction motors are used. Important users make use of hundred of such drives, summing hundreds of MW. This type of motors have technical capabilities to easily operate at variable speed.

An analytical design model for wound rotor synchronous machines

2013 IEEE Electric Ship Technologies Symposium (ESTS), 2013
Optimization-based design of electric machinery over a large design space requires the use of computationally efficient models to predict machine behavior. In this work, an analytical design model is developed for wound rotor synchronous machines (WRSMs), a key technology for power generation in marine applications.

Study on rotor magnetomotive force comparison of doubly-fed brushless machine with cage rotor or wound rotor

2005 International Conference on Electrical Machines and Systems, 2005
This paper detailedly studies the rotor magnetomotive force of doubly-fed brushless machine with cage or wound rotor, comparatively analyzes the magnetomotive force produced by rotor conductor at unit conductor on the condition that the rotor slot occupancy ratio and the conductor numbers are in consistency, and points out that, for of doubly-fed ...

Sensorless Starting of Wound Rotor Synchronous Machines

2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019
The sensorless operation of wound rotor synchronous machines (WRSM) must meet several requirements. The most important to be mentioned is how to insure starting at full load and then operating at low speed in the presence of magnetic saturation. This work presents a solution for high power machines by combining a method of rotor location by high ...

Control of rotor torque and rotor electric power in a reluctance wound Rotor Brushless doubly fed machine

2009 IEEE Power & Energy Society General Meeting, 2009
In this paper, decoupled control of rotor torque and rotor electric power in a reluctance wound rotor brushless doubly fed machine, (BDFM), is presented. The machine stator windings are fed from two separate voltage source inverters. The proposed control technique is applied to the inverters such that the BDFM is capable of producing mechanical torque ...

Accurate rotor fault detection in doubly-fed Wound-Rotor Induction Machine

2017 6th International Conference on Clean Electrical Power (ICCEP), 2017
Rotor fault diagnosis techniques developed for induction machines (IMs) are classically based on current spectral analysis (CSA). For the case of rotor asymmetry in Wound-Rotor Induction Machine (WRIM), the magnitude of the negative sequence component at -sf of the rotor current space-vector is commonly monitored in order to quantify its contribution ...

On the Speed Control of Wound-Rotor Induction Motors Using Rotor Impedance Control

IEEE Transactions on Power Apparatus and Systems, 1979
Significant 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.
