Computer-readable medium, a method and an apparatus for designing and simulating electrodynamic machines implementing conical and cylindrical magnets

A non-transitory computer-readable medium for designing a rotor-stator structure for an electrodynamic machine, the computer-readable medium, comprising executable instructions to:

• select active field pole members including coils at least one of which has a coil length parallel to an axis of rotation;
• select pole faces to confront conical surfaces of rotors disposed axially from each other, selecting said pole faces comprising:
• determine a flux in a coil region of an active field pole member to produce a value of torque, said coil region being disposed within said coil length;
• select a magnet material to produce a flux density at an air gap formed between a surface of said magnet material and a pole face of said active field pole member;
• calculate, in a processor, a surface area of said pole face at which said flux density of said magnet material provides for said flux in said coil region to approximate said value of torque;
• and
• determine a non-orthogonal angle at which to orient said pole face relative to said axis of rotation to establish said surface area for said pole face;
• and
• size said coil length while maintaining a cross-sectional area associated with said active field pole members to adjust said value of torque as one or more performance characteristics.
