Gears for electric motor

An electric motor, comprising:

• a motor shaft;
• a high magnet-coil pair, comprising:
• a high revolutions per minute (RPM) rotor operably coupled to the motor shaft;
• and
• a high RPM stator stack;
• and
• a low magnet-coil pair, comprising:
• a low RPM rotor operably coupled to the motor shaft;
• and
• a low RPM stator stack;
• the high magnet-coil pair and the low magnet-coil pair having different magnetic and coil properties;
• a controller allocating electrical current to at least one of the high RPM stator stack and the low RPM stator stack based on a desired torque and RPM of the motor shaft.

An electric motor, comprising:

• a motor shaft;
• a rotor assembly comprising:
• a plurality of permanent magnets, at least some of the plurality of permanent magnets having different magnetic properties;
• a stator assembly comprising:
• a plurality of stators, each of the plurality of stators having pairs of stator coils, at least some of the plurality of stator coils having different coil properties;
• a controller allocating electrical current to one or more of the pairs of stator coils to rotate the motor shaft.
