The first is wrong.
Watts / Amps = Volts
Volts x Amps = Watts
If I know the KV of a motor and the Volts I will be using, then how can I figure out the amps or watts?
Which watts and amp? Input or Output?
Is not possible to calculate the Input or Output power (in Watts) of a motor simply by KV and Volts. You have to measure it using instruments, or you can try to calculate it but you'll need more data.
Example...: 5700kv and 11.1v = watts or amps???? Is that possible?
5700 are rpm/v
5700rpm/v x 11.1v = 63327 RPM
