In summary, the core advantage of the EMP275DS-T2000 system is in its high torque density (71 Nm/kg), high power density (9.8 kW/kg), and the high volumetric torque density. The high torque density allows for the use of propellors at lower RPM thereby reducing the noise especially for the large torque required during take-off. The higher power density allows for higher efficiency which reduces the weight required for the battery system which is an important indirect impact to the overall weight of the aircraft, and it allows for more weight for the payload. Lastly, the high volumetric density translates to less aerodynamic drag for the aircraft, saving additional energy from lift thrust for higher range and/ or payload!
In summary,EMP275DS-T2000The three core advantages of the system lie in its high torque density (71Nm/Kg), high power density (9.8Kw/kg) and high volumetric torque density. High torque density allows the propeller to operate at lower speeds, effectively reducing noise—especially when high torque is needed during takeoff. The product's quite high power density reduces the weight of the battery system (which has an important indirect impact on the overall aircraft weight), while also freeing up more space for payload. Finally, high volumetric torque density means less aerodynamic drag for the aircraft, saving extra energy in lift and thrust, thereby enabling longer range and/or greater payload!
