BLDC Motor Designed for Lightweight Aerial Platforms

Low-power motors and drives are becoming increasingly common, particularly in large-scale products such as household electronics, toys and lab equipment. Having a flexible production line in-house seems to be a significant priority among European countries. The paper focuses on the recommended procedure for developing such a drive, presenting a real development application of a 400W BLDC motor prototype, including preliminary and endurance tests. The activities include general dimensioning, magnet selection, FEM validation, mechanical part production, stator winding, impregnation, and mechanical assembly. The prototype is tested as a free-running motor, as a generator and as a full-power motor, with those tests proving that the performance goals are achieved.
