I am bit confused about the motor operating in the four quadrants. Is this operation specific only to DC motor or applicable to synchronous AC motors as well? Please advise.

RPM to generated voltage will be characteristic of the motor Am I correct? If I read the motor specifications can i get this information?Thus - as long as the RPM is within the usual range - the generated voltage should be smaller than the DC voltage.
One other question is can i also switch in the generator mode? Will it be any advantage? Please advise.the diodes never become active,
If e.m.f. can't be sufficiently reduced by excitation control, the usual way to switch to a safe operation point is to short the motor terminals. According to SM characteristic, the machine will source a limited reactive current.One other question is can i also switch in the generator mode?
Some BLDC datasheets give this information. I doubt that all do.RPM to generated voltage will be characteristic of the motor Am I correct? If I read the motor specifications can i get this information?
If you use it as a generator ... it will generate electrical energy...that's the main advantage.One other question is can i also switch in the generator mode? Will it be any advantage? Please advise.
