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 ...
Detecting broken rotor bars with zero-setting protection
(Institute of Electrical and Electronics Engineers, 2014-03)
Broken rotor bars in induction motors can be dependably detected by analyzing the current signatures under sufficient motor load conditions. Detection becomes less dependable under light motor load conditions. There are ...
