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.

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 ...

Nonlinear control of wound-rotor synchronous-motor

2006 IEEE Conference on Computer Aided Control System Design, 2006 IEEE International Conference on Control Applications, 2006 IEEE International Symposium on Intelligent Control, 2006
The problem of controlling wound rotor synchronous motors is considered. First, a nonlinear model of the controlled motor is developed in the Park (d, q)-coordinates. Then, a nonlinear regulator is designed using the backstepping technique. The resulting closed-loop is proved to be asymptotically stable and the motor speed is shown to achieve its ...

Speed regulation of induction motors with wound rotor

IFAC Proceedings Volumes, 2013
Abstract The regulation of speed is required in many applications of induction motors, including in electric locomotives and electric driving vehicles. In this paper the speed control problem for a wound rotor induction motor is considered. The speed is controlled by changing the external resistance in the rotor circuit.

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.

The Wound-Rotor Design and Finite Element Analysis of Wound-Rotor Brushless Double-Feed Motor

Advanced Materials Research, 2013
In this paper, firstly the operation principle of the brushless double-fed motor is introduced. Secondly by means of the single-pole slot-number phase diagram, the rotor windings are designed and analyzed, and it is proved that the designed motor can assure the equality of the induced branch EMF and satisfy the demands of other electrical properties ...

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.
