DIY Design PWM Contoller for 3 HP 36VDC Motor
We just bought 2 new 3HP 36VDC motors for a really great price off of eBay. See pics.
I want to build some PWM controllers for these to help keep the price of the project down and because I like building things. I could use some help though on a few things.
How many amps should the controller be rated for? 100 amps? Larger?
Are there any designs out there for a DIYer like me?
