Hello folks, I've been getting into electric motors and such for the past several months, and I have some questions I'd like to ask directly. I've been reading tons of posts, scouring the internet for motors, controllers, etc and trying to learn some things. But I feel at this point I have some questions that I need some direct feedback on. I have a little experience with bigger RC motors, but I'm still fairly new. I am not new to building my own contraptions though, as I've built an on-road 2 person trike, and an offroad buggy. Seeing as electric is the future, and the benefits it brings, I'd like to start transferring to electric though.
So I have a few things I'd like to try to convert to electric. The first two are my motorcycle and ATV. I am still in the planning phase, but I would at least like to have some possible parts such as the motor, etc, scoped out. My current motorcycle that I ride is a CBR 600, and the ATV is a Honda 700xx. Both are very high performance machines, but deliver power in different ways (4 cylinder vs big single cylinder). I may go with a different motorcycle frame for my electric conversion, but I'm still figuring that out. So anyway, I have a handful of questions, if anyone could answer some of them, that'd be great!
After digging a whole ton, it seems to be there's not a whole ton of motors to choose from. (Correct me if I'm wrong). When building a motorcycle size vehicle, I have a plethora of motors to choose from donor vehicles, but electric doesn't seem to be the case so much.
1. The only feasible motors I can find are the ME (motenergy) series of motors and QSMotors. There are a few others, but they are either very expensive, or there isn't much information about them. These two look like my only good options, am I missing any others?
2. Are the QSMotors quality and powerful? I am hesitant replacing a good working gas engine with something possibly cheap and junk from China. Most things I've read say they are decent though? Do the hub motors last a long time?
3. I've read a lot saying the QSMotors are way under-power rated on their website, saying they can push WAY more power. Is this true?
4. I am considering a hub motor for my electric motorcycle conversion. Although based on their power numbers, I am worried that I will be very underwhelmed with their power output, vs my current CBR600. I don't expect to go 150mph, but I would still like some awesome acceleration. Would the QSMotor 8kw hub motor or 12kw hub motor be a turd compared to the CBR, and will they put out an impressive amount of torque and still accelerate fast?
5. Is the un-sprung weight a big deal for a hub motor on a motorcycle? I imagine since it's not an offroad vehicle, that it shouldn't be that big of a deal.
6. For the ATV, I am considering an ME1507 or ME1115 motor. However I am seeing that QSMotor offers a 4kw mid-drive and an 8kw mid drive (can't find as much info on the 8kw though). Assuming they can be pushed well over this limit like some people have said, does anyone have any recommendation on the ME vs QSMotor comparison here? I get the impression that the ME's are better quality, but they are also a lot more expensive. Again, the 700cc ATV is pretty beast, so I'd like something that can come at least fairly close and won't be a disappointment. But I also don't need something that is absolutely crazy overkill.
Additionally, if you have any more recommendations on motors or setups that I could consider, please let me know. I'm sure I'll have some more questions. Thanks!
