A DC Motor Model with Steady Propeller Load for Electric UAV Applications

The unmanned aircraft industry is developing safer, lower noise and more efficient power technologies to sustain the transportation industry. Electric motors have many advantages over internal combustion engines. For example, low noise, high torque, high energy efficiency and low maintenance costs. Therefore, hybrid power or electric drones are gradually becoming popular. In this paper, a steady aerodynamic load DC motor model is built in MATLAB. In order to verify the model, several electric motor propeller propulsion set of UAVs have been simulated. It is applied to several simulations. The results of the simulation show the response of power consumption and thrust output to the voltage step input. Comparison of the specific power parameters with the experimental data has been made for model verification. The verification results are quite satisfactory and show the usefulness of this model.
