Design of a Double Rotor BLDC Motor with Halbach Array Magnets

This paper is focused on a design and simulation of a 3D printed double rotor machine using Halbach array permanent magnets. This machine’s is supposed to be a learning tool for demonstration of behavior and properties of electrical machines’ magnetic field. Design of this machine according to the presumed way of production technology is described. A validation of the final design is verified by finite element analysis.
