I think so.

What is polyphase DC? I picture AC sitting on top of a DC bias.

As I understand it, Polyphase DC is the same as 'brushless DC', where the DC is switched on and off in square waves instead of pulses. Turn on 'phase A' and the poles of the stator push the magnets on the rotor to rotate. Then you turn off 'phase A' and turn on 'phase B' to continue the rotation. Switching speed controls rotational speed as long as you have enough torque to rotate.
There are ways to micro-step, where phase A is pulsed, so that the rotation is smoother at low speeds.
Although more phases are possible, I've only ever seen 3.

Reverse works, right? Is regen in this release.
|
I'll be using reverse on the transmission so I don't think I asked that yet.
Regen is asking the motor to turn slower than it is, so the motor 'generates' back to the bus instead of taking energy from the bus in 'motor' mode. So I am confident that the regen will work.

How many are in the field so far.

I think Paul answered that one ... Hmmm .. I guess Paul answered the rest as well ..
As soon as Paul has run his tests, hopefully I get one to test out.
