Abstract
An electric machine and method for powering the electric machine using interchangeable power modules that are configured to be interchangeably placed within power bays of the electric machine is disclosed. The electric machine includes an electrical module that is configured to receive power from one or more of the power modules placed in the power bays and transform, such as from DC to multi-phase alternating current (AC), and provide the power to one or more motors of the electric machine. The power modules may be of the same dimensions, same electrical interfaces, and/or same power output (e.g., type, magnitude) as each other to enable the interchangeability of the power modules. The power modules may be ones that generate power or ones that store energy. In some cases, the generating power modules may charge the energy storage power modules, while the energy storage power modules power the electric machine.
