Re: Gold and Standard external controllers
« Reply #45 on: November 05, 2010, 02:17:12 PM »
I was considering using the gold controller, but then I would not know if the differences would be of any use if I'm not using a standard controller.

Gary, apart from the obvious colour difference, what other differences are there between the standard and gold controllers?
 
 

 

Do you know if they are both limited to 60V maximum?

Is the gold one supposed to be better or more powerful etc?

Alan I suspect they are the same as the version number is v2.0.

Other than looks I suspect no difference, but the gold controller would make the owner feel more Golden owning one of these.

I actually don't mind the MC controller the way I am using it.  Its better than I thought it would be.  The wife gave the MP the thumbs up when she did her first run on it last night. Said she had plenty of confidence and power to do her run.

I have the working MP modded to run 30 amps for a few days now max and it came home from the shops cold.  

Its settings are.
48v
23amps max I get 30 amps max.
13 amps cont.  I get about 15 amps cont.

Really about 24 amps max constantly. So I have a 6 amp spike to deal with.  Not too bad.  I suspect what you got to watch for when the hub is like spiking at 40 amps and youre seeing 22 amps real time on the CA.

Mwahahaha.  I just did 2500 watts with my MP.

Nice competing in traffic at roundabouts and lights..  :D

Leslie,

It's interesting to note that you are still getting 820mA of charging current even without regen!
Presumably this only occurs when you exceed the motors maximum speed i.e. going fast downhill.

What do you reckon?

Woohoo! thats a hugh number. Im getting about 34 total with two motors and your getting 51 with one. I guess in a drag race you win! Maybe we could do some time trials like how many seconds to reach 32kph just to see the results.

No/  I'll tell you why IMO.  That reading believe it or not was from a bike that was speed limited to 35kph so the bike never reached top speed to get that 2500 watt reading.

I towed a new Diamondback MTB home in the trailer 18kms.

Yeah it could be that but it is circuit so some load resistance could be observed. Leakage when the fets switch off the diode in them is slower.

It always has been happening.  But I think if I accelerate hard and release the throttle quickly the back electro magnetic energy under high loads and hits the fet diode in this fashion at any RPM.

See that zero use of regen makes me wonder about what the wheels possibly do with high percentage regen, under load?

Hmmm how to get some more info on this... :S

Regen is a beast I myself are not game play with aTM.  It would be better having a very wide current pathway through the shunt so the volts don't get up too high between the motor and the shunt.

My modded controller is prolly more up to regen than ever.  But I cant afford to lose this build just now.

Actually I really don't know, Maybe now that I have my front motor external now I'll give it a try. But what if I like it? I already offered it to Leslie..

I went for another ride and I recalled this question, so I tested a few things.  Nope!

Actually I get that regen only when I apply brake switches.  It seems regen at 0% may actually be .01% or something like that.

But not enough to make the regen tick into the regen log with the CA.
