Depends, if phase amps are fixed and limits reached in each case I agree with you but irl you don’t always max out.
What I meant was that if you keep your max levels but raise voltage, you raise power. As such you’re most likely pumping more watts with same throttle amount, and esc will cover your extra power into more phase amps…
Thus in theory yes you don’t gain more torque but in practice your Will feel more torque because you are pulling more amps within your max limits.
At max for both yes you only gain speed and power relative to that speed.
You can have X amount of torque at any RPM, including zero (e.g. torque on a bolt), which takes zero power, or X amount of torque at Y RPM, which will give you (X*Y) power. Given the same torque, more RPM gives more power, and vice versa.
What I would like to add is that you compared a 12s2p vs a 10s2p that’s not really a representative comparison. The 12s is obviously more powerful because it has more cells. If they would have the same mount of cells you only gain top speed nothing else.
The maximum torque for longer is just a result of the bigger battery not the higher voltage.
The battery size in this graph is just so you can have 10s and 12s with the same mount of cells.
With my belt drives I take the super unscientific approach: If I can lay my hand on the motor for at least 5 seconds without it becoming uncomfortably hot after sustained riding, say at the top of a hill after 20 minutes of gunning it, I know I have headroom regarding amperage with my motors.
Not sure if most hubs have temp sensors, but that would help figure out how hot they are getting under the thane. Maybe use one of those IR laser temp guns and point it at a metal part of the motor?
On top of temperature, I would add that if it smells funny, feels like it’s losing power without the ESC being weak, or starts making suspect noises, you know it’s taking a toll
Depends on the temp rating of the winding insulation and the magnet max temp or currie point at which they lose their magnetism permanently. But rarely are those ingredients revealed. Without knowing what the material limits it’s a guess. The magnet Currie point is a hard limit and the winding temp rating is for 20,000 hours at that temp and will be cut shorter with higher temp or repeated temp shocking.
If you end up with a motor that now goes faster with a higher kv its magnets have passed the Currie point.
If you have extra heat or it won’t even turn you likely shorted it (although knowing eskate u likely didn’t finally get to the end of the insulation lifespan and instead rubbed through it with vibration shorting through the phase leads or some other loose wires)
Both the higher kv and increases resistance will show on bldc tool…if u can even get it to spin…if u can’t then it’s likely shorted across the phases vs in the windings of a phase.
I’ve got a set of cast ronins gathering dust on a push board. Any idea if these loaded hubs will fit? The ends are approximately 19mm square, but they tapper up.
