Speed estimation during the starting transient of induction motors
(Institute of Electrical and Electronics Engineers, 2020-07)
Typically, the rotor speed of electric motors was measured directly by the use of electromechanical sensors. Even though these devices are very precise, they are also fragile and expensive to install. Currently, some ...
Control Strategy of a DVR to Improve Stability in Wind Farms Using Squirrel-Cage Induction Generators
(Institute of Electrical and Electronics Engineers, 2011-08)
This work presents a control strategy of a dynamic voltage restorer (DVR) to improve the stability in wind farms based on squirrel-cage induction generators. The DVR controller is tailored to work under unbalanced conditions, ...
Voltage unbalance and harmonic distortion effects on induction motor power, torque and vibrations
(Elsevier Science Sa, 2016-11)
Voltage unbalance and harmonic voltage distortion affect the power, torque and vibrations on induction motors (IM). In this paper, we compute the frequency of the oscillations of the power, torque and vibrations due to ...
Fault diagnosis scheme for open-circuit faults in field-oriented control induction motor drives
(The Institution of Engineering and Technology, 2013-05)
In this study, a new model-based fault detection and isolation (FDI) strategy is proposed for field-oriented control (FOC) induction motor (IM) drives. Actuator faults are addressed, and specifically, single open-circuit ...
Numerical simulation of electromagnetic induction responses of 2D resistive structures as an aid for interpretation of archaeological data
(Society of Exploration Geophysicists, 2004-12)
A Frequency-domain Electromagnetic Induction System was used to characterize an archaeological site in South Patagonia. This method involves the measurement of the change in mutual impedance between a pair of moving coils. ...
Efficiency assessment of induction motors drives operating under shaft misalignment conditions
(Technical University of Ostrava, 2020-09)
Historically, the negative effects of misalignment between the motor shaft and the load on the electric drives are well known. Vibrations, loss of life of couplings and deterioration of efficiency are some of these effects. ...
Mechanical-sensorless induction motor drive based only on DC-Link measurements
(The Institution of Engineering and Technology, 2006-11)
Sensor count reduction for high-performance induction motor (IM) drives is considered. A novel strategy to compute the three phase currents, based on a single current sensor and an adaptive observer, is proposed. The ...
On-Line Model-Based stator fault and identification in induction motors
(Institute of Electrical and Electronics Engineers, 2009-11)
In this paper, a model-based strategy for statorinterturn short-circuit detection on induction motors is presented. The proposed strategy is based on the generation of a vector of specific residual using a state observer. ...
