motor controller

Hello EV Community, I recently purchased a Mars ME0909 for my Electric ATV Conversion and am moving on to looking for a motor controller and battery system. I am looking for an hour or two of operation and a range of a few miles. It is for use in the mountains so It needs to be able to climb...

First test with the motor in. Connected to 5 speed auto transmission. About 1000 bucks for the motor and controller, not including shipping. Fun kit. :D Edit: Hmm... seems the youtube BBcode tag is broken? Here is the link to the video: https://youtu.be/bNoI47iC6xE

Hey everyone! Long time lurker, second time poster. I have come to you today to ask for your opinion on motor controllers; the good, the bad, the ugly. I, like many others here on this forum, want to build motor controllers. Before I start designing I want to get your input on what makes a...

Hey guys, first post here at DIYElectricCar. I have a question about interfacing with the Curtis 1238 motor controller over CANbus. I am using this controller in a hand built boat for a club at university. I am trying to display motor data from the controller (such as motor rpms, temperature...

Hi, I recently got my hands on a Solectria UMOC435T motor controller. I'm member of collegiate engineering and design team and my team is fielding the idea of trying to use this motor controller in an electric snowmobile conversion. I'm trying to understand the wiring for UMOC's 12V I/O...

So far, I have 3 12-volt batteries that will power an electrical engine that handles up to 36 volts. I have yet disassemble the gas-related parts of the atv. My goal is to get 10 hp out of it. I have the motor controller, wires, bolts. Everything else, like the transmissions and gears is already...

Hi! I'm new here. I'm building a tricycle (see photos) and I'm trying to find a good controller. I scavenged two working wheel chair motors with tiny, high torque gear boxes. I only intend this contraption to move about 5mph, so huge torque is more important than speed. What can you recommend in...

I'm looking for a way to make a cheap and easy to build (by theory) controller. I've poked around on the forums and really liked the idea of the mechanical PWM controller (http://www.diyelectriccar.com/forums/showthread.php/mechanical-pwm-46258.html) but it looks like there are too many...
