ABSTRACT:
A motor module, method, apparatus and system for implementing linear and rotary motors, such as relatively large rotary motors, are disclosed. In one embodiment, an electrodynamic machine can include magnets having angled magnetic surfaces and regions of predetermined magnetic polarization. The magnets can include a first array and a second array of magnets arranged in a direction of motion. Also included are groups of field pole members arranged adjacent to the first array and the second array of magnets. The field pole members include angled flux interaction surfaces, which can be formed at the ends of the field pole members to confront the angled magnetic surfaces. In combination, the angled flux interaction surfaces and the angled magnetic surfaces define air gaps. As such, the angled flux interaction surfaces are configured to magnetically couple the field pole members to the magnets to form either a linear or rotary motor.
