Active broken rotor bars diagnosis in induction motor drives
(Institute of Electrical and Electronics Engineers, 2020-07)
A new active fault diagnosis strategy for broken rotor bars (BRB) in induction motor (IM) drives is proposed. The active scheme consists of injecting a zero-sequence signal online with a standard space vector PWM. The ...
Voltage Support in Industrial Distribution Systems in Presence of Induction Generator-based Wind Turbines and Large Motors
(2016)
Industrial loads are usually composed of large induction motors (IM). These motors present a critical behavior under some circumstances, e.g. during starting and faults in the system. Currently, induction generator-based ...
Projeto automático de controlador de velocidade sem sensor mecânico para motores de indução trifásicos
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2008-08-27)
This works proposes parameters estimation algorithm to auto-tune the control
laws of a speed sensorless servo. The identification process of the electrical and
mechanical parameters is based on recursive least squares ...
Predictive Torque Control of Induction Motor Based on a Robust Integral Sliding Mode Observer
(2023-03-01)
The parameter estimators and the disturbance observers are two widely used methods for the robustness improvement of the model predictive control schemes. This article presents a hybrid solution to improve the robustness ...
Estudo e proposição de técnicas para a avaliação do isolamento em motores de indução trifásicos de baixa e média tensão
(Universidade Federal de Minas GeraisUFMG, 2018-03-22)
StudiesindicatethatthesecondmostimportantcauseoffailuresinInductionMotors(IMs) is the low Resistance to Ground (RG) of the stator insulation. To identify this problem in Low and Medium Voltage (LV, MV) IMs, most of the ...
