Non-FRC Motor Controller?

[AlexH]

these are all pwm esc's

for less than 1a http://www.fingertechrobotics.com/pr...d=ft-tinyESCv2

3-9a http://banebots.com/pc/ELECTRONICS/BB-0309

the sabertooth 25 is a pretty beastly dual channel controller. it will do 25a per channel or 50a single. i run one in my 30lb battlebot. http://www.robotmarketplace.com/prod...ER2X25-RC.html
the 12 amp version isn't too bad either.

for bigger stuff http://holmeshobbies.com/product.php...4&cat=2&page=1 it will do 80a at 24v and dosent have a fan like a victor.


robot market place has a pretty cool tool to find speed controllers

http://killerbotics.com/kbtools/TentacleTools/ is a great drivetrain calculator.

i would invest in a esc instead of pulsing a spike relay and you can always re use them in another project.
