Hi Dave etc
Normally the GE etc Sepex or Finer field shunt motors use a FET H bridge that
diagonally PWM's in forward direction on the field and then when you flip in
reverse it immediately uses the other two diagonal Fets to go backwards. No
noticeable delay from forward to reverse.
Have a
What we seem to have deduced is that the controller and motor are a
matched pair. It seems without doubt that the controller manages the
voltage delivered to both the armature and the fields, otherwise the
"reverse switch" wouldn't be workable. I'd image that the sequence
would be something lik

Yes, that sounds likely.
The Lucas Bedford vans used a sepex motor. Armature control was via an
SCR, with the field driven via a bipolar transistor circuit. Battery
voltage was 216v nominal of 3KQ11 tubular plate lead acid. It was
usually the field controller that
The first version of the Reva G-Wiz is a sepex motor too.
Does anyone here have any experience diagnosing the Smart ED? Here's what's
going on with mine:
My 2013 Smart ED is no longer charging. When I plug it in to the EVSE, I hear
the usual clicking of contactors in the car, the EVSE contactor closes and then
opens again within a half second, and t

Hey Mr. Green,
I have an electric Fiat 500e that I love. I have been hearing fl
I'll assume you've tried both a level2 and a level1 EVSE with the same
symptoms.
I suggest you the search link
