Why do u tell me there longwinded basic elec explainations that aren’t related to what I’m saying. Another water analogy? How about how voltage in a motor is converted to torque.
Oo my god it’s never ending
Voltage is converted to amps. Read what I linked. This isn’t the thread and it’s been done before. I just brought it ip because pb1 defined wattage and torque with vague wording and it brought it back up. I’m done with it.
Did u read what I linked? I keep linking for you and it’s not getting anywhere. Vedder and Ren, who designed the vesc and a similar other esc, tell volts get converted to amps by the Vesc. Argue with them in vedder’s chat site, then come back and tell me how it works
I’m repeatedly saying I don’t know how it works but it’s the case. Why so stubborn. Just trying to send u the right way.
No it doesn’t imply voltage is zero and conversion doesn’t have to be complete. We both know and hope U don’t explain it again that it takes both components
Vedder quote:
The achieve the same performance on 200kv 6s as on 100kv 12s you have to double the current, which will generate four times more heat in the VESC for a given torque. The motor will not care much, but the simple answer is that the VESC is much better suited for 12s 100kv than 6s 200kv.
As rew mentioned, if you are using far less current than the VESC can supply anyway it won’t matter, but in this case I’m sure that you are using more current than that.
Regarding running a motor on low modulation with high battery voltage, that is fine for the VESC. The phase current is what will cause heat. So if you have a 200kv motor and never run more than a certain speed where 6s is enough, 12s will work almost as well as 6s heat-wise and generate less heat in the cables between the battery and the VESC. Running on low modulation and high voltage will cause more ripple though, which make things slightly less efficient.
@devin has explained a lot of electric principles, added formulas, wiki quotes etc… @Hummie You just keep quoting Vedder, who btw never said that volts are converted to amps. You seems very short sighted, and mostly driven by “experiences” you make. It’s time to get a little more theorical. But If you just want to hijack EVERY SINGLE THREAD with your "Voltage is converted to amps"sentence based on no quote by vedder and saying that “you don’t know how it is working”, please stop replying.

We’re on different pages and ur on the same page repeatedly. Just stop…check yourself…mull it over in your mind and say " do I really want to give more basic electricity examples to try to define a speed controller that’s obviusly more complex.?"
ok I’ll get the quote for u since reading the link seems to much. I keep bringing it up because it seemingly goes against BASIC electricity formulas.
I don’t know how it works. That’s what I’m asking. But I will link it word for word for u
Ren: "Do you know transformers?
You can transform 220V, 1A to 22V, 10A, right?
The VESC is doing the same, it is transforming 50V, 25A into 20.8V, 60A for your motor"
I rest. I quoted for u. Said to specifically convert voltage to amps like a transformer. Answer to that. I do read links if u find one explaining how it works. I’m here asking not telling more than that.
@Hummie Volts and amps are two sides of the same coin or two characteristics that can’t exist without each other. You can’t only have one side without the other. And one “side” does not get converted to the other “side”. I like the water analogy to visualize these electrical characteristics where the water pressure (electrical potential) is volts, and the size/diameter of the hose determines how much water (amps) can flow through that hose. This illustrates how pressure and flow are two totally different characteristics of the system, and can’t get “converted” from one to the other. Here are some examples of how they relate to each other.
Garden hose (~6s) = low pressure (volts), low flow (amps) Fire hose (~12s) = high pressure (volts), high flow (amps) Pressure washer (~24s?) = very high pressure (volts), low flow (amps)
I like to go one step further and imagine the hose diameter is flexible, like a ballon, to simulate a change in Amps, and the amount of Load on the system determines how large that hose or balloon diameter can get. At some point it will stretch too much and pop from too much Load drawing too much Power (pressure x flow) from the system. Conversely, at a small load, the hose will shrink to a very small size, and only require a small amount of flow at that pressure.
Here’s a link to hopefully describe it much better than I can.

No more water analogies please:laughing: I know ohm’s law. This is not basic electricity and it’s been said by Vedder and Ren that the vesc converts/transforms voltage to amps for the motor. Thems facts. Anyone who can explain that more in detail id like to read from.
