Online sensorless induction motor temperature monitoring
(Institute of Electrical and Electronics Engineers, 2010-06)
A sensorless internal temperature monitoring method for induction motors is proposed in this paper. This method can be embedded in standard motor drives, and is based on the stator windings resistance variation with ...
On Line Diagnosis in Induction Motors and Load
(International Frequency Sensor Association, 2018)
Induction motors are essential components in the vast majority of industrial processes. The different faults on induction machines may yield drastic consequences for an industrial process. The main problems are related to ...
A Current Monitoring System for Diagnosing Electrical Failures in Induction Motors
(Academic Press Ltd - Elsevier Science Ltd, 2006-12)
Induction motors are critical components in industrial processes. A motor failure may yield an unexpected interruption at the industrial plant, with consequences in costs, product quality, and safety. Many of these faulty ...
A Model for Induction Motors with Non-Uniform Air-Gap
(Planta Piloto de Ingeniería Química, 2005-12)
Equations to calculate inductances of induction motors, considering non-uniform air-gap, are proposed. The analyzed air-gap variations are static and dynamic eccentricity and stator slots. The equations for inductance ...
Stator inter-turn faults diagnosis in induction motors using zero-sequence signal injection
(Institution of Engineering and Technology, 2020-12)
This study presents a strategy for stator inter-turn faults diagnosis in induction motors (IMs) operating under timevariable load and time-variable speed conditions. The strategy consists in injecting a zero-sequence ...
