Abstract: For the usage requirements of low-altitude aircraft propellers driven by low-speed high-torque propulsion motors, a comprehensive analysis between the round-wire winding design and hairpin winding design was carried out from the aspect of winding pattern. The results show that the hairpin winding design has better heat dissipation performance, but it is inferior to the round-wire winding design in terms of design and processing, electromagnetic performance, overall weight, and efficiency. The results of the analysis could be used as a reference for the designers of low-speed high-torque motors in the selection of winding type, pole-slot combination, and other design aspects.

Key words: aircraft propellers, low-speed high-torque, winding pattern, hairpin winding
