Control of wound-rotor induction machine

Proceedings of Second International Conference on Power Electronics and Drive Systems, 2002
The main goal of this paper is to present a new torque and speed control method of the wound rotor induction machine (WRIM) through the control of the voltage applied to the rotor winding. The method is based on the rotor voltage orientation with respect to current using a converter cascade and a PI controller.

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 ...

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 ...

Resolver motivated sensorless rotor position estimation of wound rotor synchronous motors

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper presents a novel approach to sensorless control of wound rotor synchronous motor drives. The proposed rotor position estimation strategy is motivated by principle function of a resolver and utilizes design similarity between the controlled motor and the resolver based rotor position sensor.

Thermal Model and Analysis of Wound-Rotor Induction Machine

IEEE Transactions on Industry Applications, 2012
This paper presents a simplified thermal model for a wound-rotor induction machine. The thermal model is based on lumped parameters, and the analytical equations for their computation are provided in this paper. The procedures for the thermal model setup have been discussed and validated on a 3.8-hp wound rotor machine, comparing the predicted and ...

Proposal of a 2DOF Wound-Rotor Resolver

IEEE Sensors Journal, 2021
Two Degrees of Freedom (2DOF) electrical machines are widely used in robotics. They need position sensors for their electronic commutation and high performance control loop. 2DOF resolvers are the best choice for such applications. Therefore, in this paper a new configuration is proposed for rotational-linear position estimation.

Stepless starting of wound-rotor induction motors

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1962
This paper gives experimental and calculated speed-torque-current curves for a slip-ring induction motor with an automatically controlled secondary impedance to obtain stepless starting with low current, high sustained torque, and low full-load slip. A saturable reactor in the secondary circuit is supplied with a control current from a direct-connected

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 ...

On the wound-rotor induction machine control

1997 IEEE International Electric Machines and Drives Conference Record, 2002
The main goal of this paper is to present a new torque and speed control method of the wound rotor induction machine (WRIM) through the control of the voltage applied to the rotor winding. The method is based on the rotor voltage and current orientation using a converter cascade and a PI controller.
