Unfortunately, one big 2200uf cap is gonna take up just about as much volume as three 680uf ones. The density of capacitors is pretty much constant - three times the capacitance, three times the volume.
If you relocate it far away, you may have problems
If you make it smaller, you may have problems.
If you remove it, you’ll have problems.
They’re where they are, and the size they are, and the type they are, for a reason.
Might I suggest saving space in less risky ways, like removing extra insulation from your wires?
What @MysticalDork said, but also you can add a smaller cap like maybe 10μF where the original ones were and then put the 2200μF ones a couple cm further away, but the added distance from the cap to the FETs is a problem but a smaller cap between them, as close to the FETs as possible, does help ameliorate that problem.
yep because it will have more wire coil and also more W possibly. It will also in theory have better heat dissipation. other than the above and the size difference then nothing much
haha, no, motor kv will change speed and usally the bigger the motor it will allow to have more power and speed. like 2x5060 170kv motors won’t have the same power as a 2x6380 170kv so expect a lower speed if going up hill. maybe the same if going flat but i will take longer to get to that top speed. Bigger is better generally speaking performance wise.
@BillGordon i bet the only one left is LiquorLand. Can @longhairedboy create a ‘‘wine tasting’’ badge.?
okay, so currently feel that with slight resistance (wind) or inclines i dont reach as much topspeed as i would on flat, this is where the bigger motor with same kv would help reaching my calculated topspeed more easily , is this what it means ?
ok so i just figured the bigger motors im talkin about are actually 6374 and not 6369, and sport 500w less peak performance than my (same brand) 6355… not worth the exchange on my current setup i would assume
edit: atleast asking stupid questions leads to more knowledge
Careful with watt ratings on motors. They’re more of a safety limit than power level.
Motors are very dumb devices. They will take whatever you throw at them until they melt. You can even over or under volt your motors and have lots of fun until they melt (over bolting).
The larger motor cans dissipate heat faster so they can handle larger amp draws before getting into a danger zone.
Remember,
Power = Current x Volts
You don’t “get” more power by having a larger motor rated for the same kvs. You can just handle it better and therefore throw more current at them before they overheat.
Would it still be possible to do some decent trail riding/light offroad on 170kv motors on 1:3 gear ratio on 175mm pneimatics, or is the ratio/kv too small?
i would assume that if your calculated topspeed is around 45km/h with those motors and 12s, there should be some torque / braking performance left, but im just talking out of my ass here
if thats still desirable in efficiency and if that kind of reduction is even possible - no idea
