Computational Efficient Parameter and Performance Prediction of Wound-Rotor Induction Motor

IEEE Transactions on Magnetics, 2018
A basic, fast, and accurate steady-state finite-element analysis (FEA) based parameter and performance calculation method for the wound-rotor induction motor is presented. The method couples the circuit equations with field equations using the principle of frozen permeabilities to present the voltage-fed induction motor.

Mathematical model of the wound-rotor three-phase induction motor

Russian Electrical Engineering, 2007
For 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

Control of a Three-Phase Wound-Rotor Induction Motor Drive for Automation Applications

2019 IEEE International Electric Machines & Drives Conference (IEMDC), 2019
The 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, 2010
The 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

1988
The 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
