It’s accurate but as you can see form the video, the coils can be burnt by the time the heat propagates outward. Just depends on how hard you hammer it and how many amps. The sticker can help if you don’t push it too hard. I have links to all my stuff on the wiki: forum.electricmoto.org/t/mx500-mx650-and-rsf650-wiki/28#other?from=compvideoevo Towards the bottom.

Nice vid. Does your belt conversion hold up well with all that power? How many teeth do you need to use on the front sprocket to create enough tension?
The extremely overkill kit holds up well to the cricket’s 200/400 amps. I have issues with fardriver and Kelly with more than about 80 amps on the v1 kit though.
@@beltsNshit I have an RSF650, just ordered an ec4p and already have a Kelly controller that I will be increasing the amp draw with the new motor. Will a 14 tooth handle this or would I need a 15 tooth to handle the power? I would prefer a lower tooth count for more torque.

Correct. This use case is not where the heatsink will make much of a difference. If I let off the throttle even for a little bit the heatsink would have done wonders. I tested with a heatsink as well but there wasn’t any real difference in the my1020.
Maybe add the heat sink, large vent holes (as before) with ceramic bearings and maybe a little external fan, like a computer fan. You don't need much convection cooling to make a huge difference over heat conduction cooling (no fan). Ceramic bearings option PEEK 6001 Ball Bearing PTFE Cage Si3N4 Ceramic Balls 12x28x8
Drilling out the end caps isn’t an option for me. I ride in wet conditions and want to minimize motor rust. A heatsink and fan would do wonders if I let off the throttle more but for this test I wasn’t seeing any difference at all. The coils are not on the outside and heat up super fast when you push it on a 15t front.

Was thinking to use one of these as a 350-550 watt *generator.* (light and compact as possible, hopefully.) This should give some idea as to how well it will work when driven by an engine.
@@beltsNshit uh, not really. 1) I need about 50-55 volts DC. Car alternator would need serious modifications. 2) higher efficiency. Car alternators are cheap and compact, but are maybe 50% efficient unless modified heavily. Much of the anticipated use would be “out in the sticks” to charge 52 volt nominal batteries.
I just received my EC4P today. I have to wait on the rest of my parts before I can try it out. Have you had a chance to try out the KVD7212NX controller? Looking forward to that video.
Ah I see. Yeah I can’t wait as well. I have not tried even a my1020 on a Kelly controller. I am spoiled with vesc. I just hate going through cryptic old programming steps on these controllers. I have a vesc that can do 32s and like 800 phase amps. I am hoping to hook that up to the ec4p and see just how hard it can be pushed.
@beltsNshit I have been eyeing the Go foc G300. But I need to see if the KVD7212NX will serve may needs 1st. There's no sense in throwing good money away if I can get the performance I want out of the KVD7212NX. I only need a top speed of 45mph.
I have had iffy results with flipsky. They don’t seem to list the battery amps of that controller so I am not sure how powerful it actually is. I like my friends controller(little focer). It can do 100-120 battery amps and 250 phase amps. Though for this motor might as well get a bigger controller. Maybe one that can do 150-200a like the enc cricket.

No problem. Wish I had more time to do this
The overlays look really good.

Great info.
Good feedback. I actually saved up some and got a lapel. I’ll be sure to use it for videos like these in the future. 😊

No problem 😉
can you put the ec4p internals in a my1020?
Y’all live fairly close to where I do. Recognize some of those landmarks while crossing the hill on Halsey near 102nd.
Yeah seems like it. Shoot me an email maybe we can meetup and go for a ride sometime.
