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

Mathematical model of the wound-rotor three-phase induction motor
Russian Electrical Engineering, 2007For the wound-rotor three-phase induction motor, the main equations are presented and a structure for the mathematical model is developed that makes it possible to calculate transients in the electric motor and the electric drive taking into consideration the distributed winding, saturation, and eddy currents in the stator and rotor teeth. The model is

Modelling and analysis of series-connected wound rotor induction motor
2008 18th International Conference on Electrical Machines, 2008Wound rotor three phase induction motor with series connected stator and rotor winding is an object of analysis in this paper. This type of connection enables specific operating regime when induction motor works as a synchronous motor at double synchronous speed. Electromagnetic torque analysis shows that other synchronous torque could also be expected

Control of a Three-Phase Wound-Rotor Induction Motor Drive for Automation Applications
2019 IEEE International Electric Machines & Drives Conference (IEMDC), 2019The use of rotary assembly platforms, such as the automated box-fill system rotary table, is widespread in automation applications. One of the problems that the designers have to face is how to transfer the power to the auxiliary actuators mounted on the rotating platform.

Stator current harmonics in saturated cage and wound rotor induction motors
The XIX International Conference on Electrical Machines - ICEM 2010, 2010The analytical expressions for stator current harmonics frequencies in the spectrum of saturated cage and wound rotor induction motor are derived in the paper. Knowledge of stator current spectrum of healthy motor supplied by symmetrical three-phase voltages is the starting point for application of the most popular noninvasive diagnostic and condition ...

The slip energy recovery system for wound rotor induction motors
1988The overall principle of slip energy recovery systems (or 'static Kramer systems') is to insert a variable back-EMF into the rotor circuit in such a way that the resultant energy can be recovered and fed back into the AC mains network which is feeding the stator of the induction motor. The result can then be an efficient method of reducing the speed of
