I saw this article randomly which listed the torque specs of the motor at around 100nM, now my car is NA probably makes less than 100nM at 1000rpm and peak probably 220nM at 4000-4400rpm or so

This motor is only 600-750W and puts our ~100nM of torque. And basically from 0rpm since it's an electric motor across the whole range.

Using this as an assist motor for acceleration on the crank wouldn't I get a significant noticeable boost to acceleration, especially off the line from 0rpm where it feels weak?

What am I missing here? 100nM is 100nM. I always thought I'd need like a 25kW motor to make this work, which I found a few suitable motors

>but the gearing
Can be tuned specifically to make this work, giving max output rpm to like 6000rpm or even 4000rpm (considering likely wouldn't need assist above this)

>your alternator power output
I never planned to run an assist off the alternator, but off of lifepo4 lithium batteries and just charge them during cruise

>overheating
Not always on, mostly off and used during heavy acceleration demand starting at lowish rpms below 4000rpm only, almost always off

I'm really suspicious because 750watts only, but surely an extra 100nM is an extra 100nM right?

I'm not considering that exact motor but it's making consider I don't need as huge of an electric motor as I thought to make this idea work

I can not help you.

>ebike garbage
Die you fucking /n/igger

>Can I use an electric motor to boost my engine
Yes, not you, since you are asking for shit people did years ago.

>>28523552 (OP)
That sounds gay. Put a 2 stroke inner instead.

Nm I'm retarded, it's probably like 100 rpm max.

>>28523552 (OP)
This motor already has an internal gearbox, so max rpm is about 70 (based on max torque and max power figures). 100Nm at 4000rpm would correspond to 42kW, which would make for a pretty potent bicycle..

There's actually a whole community to these and race them. Some people even make billet cases that go for a good chunk of change.

scrap that shit and put a honda engine in the back of a gokart with an ebay hotside and turbo

>assist motor for acceleration on the crank
like an 2nd alternator (anti-alternator)? or a motor hung off the crank pulley w/ an 'oldham coupling' like old prochargers?
seems easier to e-drive the differential if rwd like the old DoE electric S-10s
or retrofit an OEM hybrid transmission and use your own inverter/battery

>100nm
marketing lies
likely torque after gear reduction - stacked onto the bldc motor.
ebike shit is usually sintered planetary gears <10:1 - so really a 10nm motor

i have a 40:1 cycloidal/harmonic reduction that nets 275nm after reduction from a cola can sized motor.

>gearing
more to spinning stuff than just gears
>torque. And basically from 0rpm since it's an electric motor across the whole range

power is still torque * rpm
the motors winding 'kv' determine rpm per volt - a higher kv will net more power but at a higher rpm. basically choose the highest reduction gearbox and max out the kv to get your 4000rpm target for e-assist. many smaller low turn count motors spin @ 20k - but a 5:1 reduction box is doable
torque is also a function of stator diameter - so on a car you likely dont have the same packaging limitations as an ebike
the larger stator can also accept more wire turns, and thus run slower rpm with less reduction
something like a 10" ebike hub motor can get down to 10rpm/v (ie needing 400v to get your 4000rpm)
