A study of design process of BLDC motor for aircraft hybrid drive

Abstract

A study of the design process of BLDC motor designated as a power source for an Unmanned Aerial Vehicle (UAV). It was assumed that the UAV would be powered by a hybrid system, where electric power source operates in parallel to a combustion engine. Geometry of the electric motor being designed is presented as well as how the shape and magnetizing method influence cogging torque and average torque of the motor. Regulation characteristics, instantaneous currents, voltages and electromagnetic torque values are presented. Motor performance was analyzed as well as losses versus deliberately selected control parameters.
