Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

The loss of excitation (LOE) in synchronous generators represents a critical fault condition that can lead to severe operational disruptions and damage within power systems. Under normal conditions, ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...
