Abstract

This paper presents the design and prototype development of 2.2 kW Axial flux PCB stator motor, compared to the conventional permanent magnet type of electric motors. This construction eliminates the iron core, as a result there is a reduction of weight, cogging torque, noise and increase in efficiency. Analytical design was done, and prototype is developed with 8-layer PCB board with 6 Oz of cu is used to build the required power.
