270KV Test Notes (datasheet)
Analytical Graph of Motor Operation definitions: I - Current, P - Input Power, η - Electrical Efficiency, T - Thrust, N - Rotational Speed. Data measured with an input voltage of 48 V, at a temperature of 25°C and sea level. Rotational speed adjusted by throttle.
The above data are the theoretical values when the input voltage is 48V, for reference only. In the case of room temperature of 25°C and no additional cooling device, the current over 53A is non-working zone, 15-53A is short-term (about 10-30s), working zone, and below 15A is sustainable working zone. In actual use, please control the motor running time according to the working environment temperature and heat dissipation conditions.
