Nettet26. sep. 2024 · You’re therefore trying to find a motor and propeller that can produce at least 1 kg. Let’s say you find a KDE motor, and a 9×6 propeller. For 1 kg of thrust, that motor/prop combination has a torque and RPM far from the motor’s max efficiency line, meaning that you’re consuming more current than you need to for 1kg of thrust.

The synchronous speed of the rotor in RPM N = 120f/P where f is the frequency of the stator current and P is the number of poles. The operating speed No = N - Ns where Ns is the slip speed. The frequency of the rotor current fr = Ns x P/120, so fr = 0 if the slip is zero. If the operating speed is zero, Ns = N and the frequency of ...
