Will it work? I want it because it has a 60A current rating and I live around lots of hills and I want to be able to haul up the hills without any trouble.
 
Wouldn't recommend it. The motor has a max current draw of 80a, using a 60a is asking for trouble, especially on those hills. More along the line of:

First that's not called an ESC but a controller.

The watt rating of the motor is not an issue since that controller has a current limit that will hopefully keep amps to a level it can safely handle.

The main problem with using the 6374 on this controller is it's sensorless (no hall sensors). Do a search for people using Kelly Controllers with RC outrunners, I'm pretty sure a few have done that.

electronic speed controller :) It may not be always called that in the ev world, but in the RC world, it is an ESC :) and since I am a RC guy, it's an ESC ;)


Anyway, I've seen them called both ESC and just controller. So yeah :)

That one from Aliexpress is certainly a tempting price. :shock:

I was thinking that was something that may make it not work (because I've seen some that REQUIRE sensors to operate at all), and I didn't know if this one was like that, which is why I asked. :) I was looking at the Kelly Controllers but so pricey :eek:
 
the eBay controller didn't mention sensors, I automatically assume it'll require them if it doesn't SAY sensorless. I linked all sensorless.

Kelly has a strong following, there's people here who say that's the best for the RC motors. There's also people in numbers using the Greentime on nonRC motors, one big proponent is EvolutionGTS. If you go with the Castle or another RC controller, they're a bit vulnerable, I should have linked this: http://www.rcdude.com/servlet/the-2224/Castle-Creations-Cap-Pack/Detail You're also needing a bec to connect a servo tester to. http://endless-sphere.com/forums/viewtopic.php?f=28&t=12196

I'm curious what the difference is supposed to be between an ESC and just a controller.
 
forget any e-bike sensorless controller driving this motor unless you are planning running 24v or less .. all e-bike sensorless controllers i have tested can only run up to around 3-4krpm for this type/kv of motor
 
You can get ultra high RPM firmware for up to 100,000 ERPM (rpm x pole count) for the Kelly, but at a hefty $100 price tag...


Question:
How can I go about mounting hall sensors to this motor?

Kelly sensorless controllers are not for use with vehicles, it's written on their page.

You know what though? Neither is the RC equipment. They too post this. But we're just outta control around here, we even put 16" motorcycle tires on 20" bicycle wheels. What do you think THEY would say to THAT?

The manual says:

http://kellycontroller.com/mot/downloads/KellyKSLUserManual.pdf


First, they are 17000 erpm max:

"15) Up to 17,000 electric RPM. (Electric RPM=mechanical RPM * motor poles)"

And it says they aren't suitable for vehicles:

"It is suitable for fans, water pumps, air conditioner compressors, fridge compressor applications and etc. "

So I would skip on that one. But at least they upgraded the throttle control so you can use it with vehicles, it used to be impossible.
