The aim of the paper is to present a method for evaluating brushless DC motors (BLDC) for fixed wing Unmanned Aerial Vehicles (UAVs). Selection of a BLDC motor, which operates in its efficient region for a UAV platform's specifications, will affect the endurance capabilities of the UAV platform. A four-constant model is presented as a means of modelling and predicting the characteristics of BLDC motors. Further, physical testing of each motor is performed on a constructed motor test bench. Validation of the model's results is compared to physical testing. The methods presented provide a means of accurately characterising a given BLDC motor. This data can be used to design the additional components used in the UAV's propulsion system.
