Abstract: In implementations of the present disclosure, a rotating electric machine includes a rotor assembly supported for rotation about a rotational axis, the rotor assembly including a plurality of rotor poles, the rotor poles being supported for rotation about the rotational axis, and a stator assembly including a plurality of independent stator modules with each stator module including multiple independently energizable stator segments, each stator segment defining a plurality of stator poles of the stator assembly for magnetically interacting with the rotor poles, each stator module being independently removable and replaceable from the stator assembly to adjust the total number of stator poles included in the stator assembly, and/or to vary the maximum power output of the electric machine.

Abstract: In some implementations, the present disclosure provides an electric machine including a rotor assembly, a stator assembly comprising a plurality of stator modules, each stator comprising multiple, independently energizeable stator segments, each segment having a corresponding electrical connecting point, and a plurality of bus bars connected to the electrical connecting points of the stator assembly, each bus bar corresponding to a different phase of the machine and electrically connecting segments of multiple stator modules. The stator modules and their electrical connecting points are arranged such that spacing between adjacent connecting points within each stator module differs from spacing between adjacent connecting points of different modules.

Abstract: In some aspects, the present disclosure provides an electric machine including a rotor assembly having a plurality of rotor poles, and a stator assembly having a plurality of stator modules, each stator module including multiple, independently energizeable stator segments each corresponding to a segment position within the stator module. The stator modules are electrically connected to form sets of interconnected stator segments, each stator segment set including at least one stator segment from each of multiple stator modules and corresponding to a different electrical phase of the machine, and each stator segment set includes segments from different segment positions within their respective stator assemblies.
