I have a couple of questions concerning the regenerative mode of operation
with an Etek motor in combination with a Sevcon 4-quadrant controller.

My reason for the questions is to assess the suitability of the motor as a
generator for a wind turbine.

Using a 48V system, what is the slowest RPM that the motor can achieve
useful charging current. For example will it still be able to produce 20A
at say 600rpm into a 48V battery.

The other question concerns the current limit. Is it possible to set the
current limit in regenerative mode so it does not exceed say 50A.

I am also interested in comments on these units from anyone actually
operating them in 4-quadrant mode in vehicle applications. Are there any
particular concerns or detail to be aware of?
