10 kW
Hey all,
just wondering if it is practical to replace the stator on a IC motorcycle with a BLDC motor.. It seems to me like the stator is about the same size as some of these small(ish) motors capable of peaking at 10(ish) kW
I was thinking it would be really cool to pull off the existing stator, attach a RV160 short or something (5 - 10kw in power) and bolt it onto something small like this:
https://en.wikipedia.org/wiki/Honda_CBR125R
The idea would be to create a hybrid motorcycle, keep the battery quite small, for regenerative braking and acceleration assist. an RV160 on a CBR125 motorbike would double it's power for acceleration,
Challenges:
There's a cheap $1200 Honda CBR125 that I want to buy and I think it'd be a fun project.
floor open for discussion...

Challenges:
- we'd have to come up with a DC/DC converter to charge the existing 12V lighting and starter system but that should be easy, it's just a DC/DC converter into the existing 12V battery. Though, we'd have to run the system at very light regen constantly to avoid discharging the existing 12V battery (or will general braking cover this scenario??)
- physical mounting considerations (new housing or stator cover.) is it possible to attach to existing shaft? I would think so?
- interface between existing throttle / brake for power control and braking
- (for the above point simple solution could be at 3/4 - full throttle twist it just provides max electric assist, so it's like an instant 10kw boost only if you'r accelerating hard... or just linear control somehow
- braking could be a pressure sensor, to provide variable braking input varying with hydraulic pressure... to match the feel of the current braking system. this is engine braking only, so having the clutch in won't help.... it'll just stall the motor
- battery size and location and capacity (I'm thinking 48V, 10Ah Lipo or 18650), this will be quite small, light, electronically limit consumption to 5Ah to improve longevity.
- controller only for boost / regen applications so it can be physically small due to not requiring extended heavy load.
- bolt on solution (somewhat) to a very *VERY* common bike design
- simplified ADR compliance considering it is not exclusively EV powered.
