Modular variable pole electric motor system

A vehicle including a modular variable pole electric motor system comprising:

• a stator comprising a plurality of stator coils;
• a plurality of modular rotors comprising at least one modular wound field rotor, at least one modular induction rotor, at least one modular permanent magnet rotor, and at least one modular synchronous reluctance rotor, wherein each of the plurality of modular rotors is configured to be removably electrically coupled to the stator;
• and
• an inverter system, wherein the inverter system:
• comprises a plurality of switches;
• is electrically coupled to the plurality of stator coils of the stator;
• and
• is configured to be electrically coupled to a battery system and convert a direct current (DC) voltage from the battery system into alternating current (AC) to individually energize each of the plurality of stator coils of the stator.
