Modelling and analysis of series-connected wound rotor induction motor

2008 18th International Conference on Electrical Machines, 2008
Wound 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

Motor Protection Device For Wound Rotor Induction Machines

2020 IEEE Problems of Automated Electrodrive. Theory and Practice (PAEP), 2020
Many electric adjustable speed drives in ukrainian industrial enterprises still use wound rotor induction machines (WRIM) regulated by varying rotor resistance. The rotor resistance changing is done by means of mechanical contacts. The presented work focuses on one of the cases of WRIM failure – overheating of rotor windings.

Bifurcation Analysis of the Wound Rotor Induction Motor

International Journal of Bifurcation and Chaos, 2015
This work deals with the bifurcation phenomena that occur during the open-loop operation of a single-fed three-phase wound rotor induction motor. This paper demonstrates the occurrence of saddle-node bifurcation, hysteresis, supercritical saddle-node bifurcation, cusp and Hopf bifurcation during the individual operation of this electromechanical ...

Irregular windings in wound rotor induction motors

Electrical Engineering, 1934
The importance of using regular windings in polyphase wound rotor induction motors is stressed in this paper. Harmful effects upon the efficiency, power factor, breakdown torque and noise of the motor may result with an irregular winding, due to differential leakage. The Goerges diagram of tooth fluxes is presented for studying this phenomenon.

Control of wound-rotor induction motor with rotor impedance variation

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 2002
It is proposed to modify the performance of a three-phase induction motor, fed from a conventional three-phase supply of constant voltage and frequency, by the use of a network of general, slip-dependent impedances connected externally into the secondary circuit, via slip rings.
