What is the best controller for a Netgain Impulse 9 motor.

Post by Faltig »

Hi all,

I have a Netgain Impulse 9 motor that was in a converted car that I purchased not "running".

I found the controller had failed and burnt all its Mosfets (DIY paul and Sabrina type board)
Then I went and bought a cheap 500amp rated controller from ebay (powersolutions in Hungary)
Unfortunately all these options have failed on me.

What is everyone else running in there builds?
I am thinking a Zeva MC1000C controller.

Any advice would be apriciated.

I second the ZEVA MC1000C as being a good controller.
I had one in Volts (a mazda 2 conversion with an impulse 9 motor and 136v 100Ah batteries)
Being able to have the display in front of you showing motor volts/amps *and* battery volts/amps was really good at understanding which was the best gear to be in.

where are you located? controllers also have a tendancy to be sitting on peoples shelves, if you're local

It's only anecdotal but I have a zeva mc600 in my car and I haven't had any trouble with it (touch wood). Though it's pretty quick to complain on hot days about over temp, but it also has never de-rated because of it and will cool back down quickly once I stop working it.
A larger cooling fan that I fit a few months back has made it a lot less prone to that issue.
All in all I'm happy with it and if it went bang I'd probably replace it with the same thing.

also, have you tested the motor with 12v?

If not, it wouldn't hurt to do it before hooking up another motor controller.

Some failure modes can result reduced inductance *and* resistance, which means the motor controller is less able to regulate current leading to power stages blowing up.

it gets less likely the bigger the controller, and the faster it's hardware current limit response is.

at 12v, if the motor spins, you should be okay.
if it doesn't, it may have shorted turns, in which case I would investigate further

I will test that as soon as I get a chance Matt. I feel a bit silly. Between the last two controller changes I removed the motor and visually checked it out. Looked great. But I didn't do the 12v test.

I am in Tasmania. I haven't put the call out yet to see if anyone has a controller laying around.
