What controller do l need??

[Bgt2u]

I have purchased a Motenergy ME1202 motor, and would like to know which controller would be the best for it. I will be running the motor at 72v......any suggestions? https://www.electricmotorsport.com/me1202-brushless-motor-24-72v-5000rpm-10-kw-cont-24-kw-pk.html

I think something like a Kelly KLS72501-8080IPS would work. Make sure you get a controller that can handle sine/cosine speed sensors. Most don't.

Great, thank you for the recommendation. I checked it out,, and wow, those are pricey! It figures (being my luck) that that particular controller is pretty much the most expensive one on their whole site. However, if that is the one that l need, l will save up for it, and get one. Thanks again......much appreciated.

I see that that Kelly controller comes in a 500A, 600A, and a 700A version. Which amperage is best suited for the Motenergy ME1202? I also am assuming that l would need the controller with the Sine/Cosine motor speed sensors, not the hall sensors, is this correct? Thanks again.

Well, with that controller the 600A version looks like it would cover your peak amperage with that motor (KLS72601-8080IPS). Do you have batteries that can put out 600A though? Or the 180A continuous the motor can do? That's a lot of amps! What are you doing with the motor?

By the way, I'm not telling you that is the only controller for you. I just happened to remember that particular one had the right sensors.

Right now, l have enough batpacks to put out 200A, and will slowly (when l have money) add more batpacks. This motor is going to be powering a custom made very small one seater, 6 wheel drive, 6 wheeler, that l am in the process of building. The motor will turn a chain drive LSD, powering 3 wheels on each side, using a brake/skid steering system. I chose the Motenergy 1202 motor because it has 60ft lbs of torque (max) and is also water resistant. I wanted enough torque due to the enormous stress required for turning. The vehicle is only 50" long, and 28" wide, with 16" tires. It should have a top speed of about 28mph.

That's one **** of a project. Keep in mind the ME1202 is not meant to drive a chain and will have to have another bearing added along with shaft modifications. There are pother motors with lots of power that would just require the proper motor sprocket and key. More power to you if you can do those mods, though.

Even though l was aware that the ME1202 is meant to be attached to a transaxle, l appreciate you mentioning that. Otherwise l would have been in for an unpleasant suprise. What l am doing to get around that, is making an extended mounting bracket, with two pillow block bearings, and an extended 19 spline shaft (with the sprocket on it) mounted between both bearings for the needed support. Yes, indeed there are other motors, with the same output power, that are definitely easier to just add a sprocket to. I came across this motor, and it is new, for only $179.00 shipped! (normally they are about $600), so the extra mounting, and a couple of bearings was worth it to me. I am a retired Electro/Mechanical/Structural Engineer, and l have a welder, and a plasma cutter, so it's not a big deal. I have built many custom vehicles, and just wanted to go with 6 wheels this time, instead of the normal 2, 3 or 4.

That's a really good deal. If you can make all the mods yourself, it seems more rewarding than just buying something anyway. It doesn't sound like it will be a problem for you.
