250KV Notes (from datasheet)

  • Analytical graph legend: I = current, P = input power, b7 = electrical efficiency, T = thrust, N = rotational speed.
  • Measurement condition note: data measured with input voltage of 48 V, temperature of 25C, at sea level; rotational speed adjusted by throttle.
  • Reference-only note: When room temperature is 25C and there is no additional cooling device, current over 47 A is a non-working zone; 13 A to 47 A is a short-term (about 10-30 s) working zone; below 13 A is sustainable working zone.
