Q: Why is torque more important than speed for heavy lift drone motors?
A: In heavy lift applications, torque is more critical than speed because torque determines how much force the BLDC motor can apply to spin large propellers. Unlike racing drones that need high RPM for speed, heavy lift drones rely on big, slow-turning propellers to generate stable and efficient thrust. A motor with high torque ensures the drone can carry heavy payloads without straining or overheating. More torque also provides smoother control and stability, which is essential when carrying expensive equipment like cameras, sensors, or delivering cargo. In addition, higher torque allows for longer propeller blades, which are more efficient in moving large volumes of air. Prioritizing torque over raw RPM ensures that the motor can sustain flight under heavy loads, reduce energy waste, and extend the overall flight time.
