Wanted to Buy: low voltage DC motor controller

Post by 4Springs »

Item: Low voltage DC motor controller
Location: Launceston
Item Condition: Used or new
Reason for purchase: Educational
Price range: ALAP
Payment Method: Paypal, bank deposit
Pickup Method: TBA
Extra Info:

Our club is working with a school on a simple EV project. They have a Netgain Warp motor and they are mounting it on a frame. They would like to hook it up to make it run. We'd like to keep the voltage low to keep the risk down - probably 24V.
If this project looks neat then it will probably be taken to motor shows etc. by the club.
Does anyone have a low voltage DC motor controller to sell us? Low cost is a must, free would be even better.

I think you can find kits at Jaycar or Altronics - any universal motor speed controller will work, as they are effectively brushed DC motor speed controllers. I've been wanting to build some small, modular AC motors for demonstrations too. Mainly for me to improve my understanding of motors...

The school ended up buying a new Kelly Controller.
24V, 100A, details here: http://kellycontroller.com/kds24100e100 ... -p-74.html
Works well - the motor makes a satisfying vroom!
We are hoping to set up ammeters, voltmeters etc., so it will be interesting to see how much of that 100A rating this controller can actually deliver.
