The "Is My Math Right?!" Thread

What is the answer to the Ultimate Question of Life, The Universe, and Everything?

Really it’s 42 lol

I thought 36 V at 95% DC = 34,2 V 1440 W / 34.2V = 42.105 A 42.105 A * 0.016 Ohm = 0.674 V 34,2 V - 0.674 V = 33,53 V 33,53 V * 190kv = 6370 RPM 6370 RPM / 60 seconds = 106.17 RPM/s 106.17 RPM/s / (36 Wheelteeth/14 Motor Teeth) = 41.29 Wheel RPM/s 41.29 * (0.097 wheelsize in meter * 3.14159265359) = 12.58 m/s 12.58 m/s * 3.6 = 45.29 km/h

So at 45 km/h i should still be able to reach a power of 1440 W. But in reality it happens earlier. So something is missing. Maybe the Motor H but my undertanding ends here.

And what would be the formula when we have the H value? To make it easy lets do the math for hummies values.

Doesn’t matter. When we can calculate at which voltage he still could achieve like 1440 watts then we could do the math for any motor.

Let’s do the math for hummies because i am not at home to check the values at the moment. Later the parameters can easily be changed in the formula to calculate it for any motor.

Of course i can confirm later on.

I have the values for my SK3 190 kv

R = 0.01627 L = 13,12
