You'd require a Permanent Magnet motor to use the regen feature on that controller.

Most EV motors are Series Wound Motors, which to my understanding there is no way to have actual "regenerative" breaking from these motors, only forced motor breaking which takes up energy.

You forgot to mention shunt wound motors which can also do regen. Some people perfer to call them seperatly excited motors since the controller controls the shunt field and armature independently.

A 144 v controller is not that much, They run between $1250 and $ 1615 depending on the AMPS you have to remember when looking at that controller that is is being MARKED way up. I have a price list of the true prices if you are intrested

[Dan Frederiksen]

I would very much like to see those prices

Hi, since I do not know what you are interested in specifically, I am posting prices for the automotive controllers and not the smaller "golf cart" ones.
Let me know if you have anymore questions
48-72 volt 550amp $980
48-72 volt 750amp $ 1,115
48-72 volt 1000amp $ 1,280
72- 120 volt 550amp $ 1,210
72- 120 volt 750amp $1,345
72-120 volt 1000amp $1,480
120-144 volt 550amp $ 1,250
120-144 volt 750 amp $ 1,345
120-144 volt 1000amp $1,615
120-156 volt 550amp $ 1,345
120-156volt 750amp $ 1,590
120- 156 volt 1000amp $1,825

except the kelly controllers do not currently support shunt wound motors...

Their site says they do.

However they only go to 72 volts.... so only good for a small car or motorcycle

hot damn, they keep adding controllers don't they....

my appologies! But you're right, they're still limited to 72V.

They do have controllers with higher Volts:

but no where near the price of the other ones you were looking at.

you're comparing apples and oranges..... shunt wound controllers and series/PM high voltage controllers.

I did not see that. Man you learn more everyday. And as I have no idea about the difference, would you mind explaining?
