Permanent magnet assisted wound field machine

An electric machine, comprising:

• a stator including an interior surface defining a rotor cavity and one or more coiled windings;
• and
• a rotor disposed within the rotor cavity and rotatable about a rotational axis, the rotor comprising:
• a rotor body,
• one or more poles each having a pole body extending between a proximal end that is coupled to the rotor body and a distal end spaced from the proximal end, one or more pole shoes coupled to the proximal end, the one or more poles defining rotor air gaps spaced circumferentially with respect to the rotational axis,
• one or more electromagnets coupled to the rotor body of the one or more poles and extending between the proximal end and the distal end,
• one or more wedges arranged in the rotor air gaps and extending between the rotor body and the pole shoes, and
• one or more permanent magnets arranged between the one or more wedges and the one or more pole shoes.

A vehicle, comprising:

• a vehicle body extending between a first end and a second end;
• a power reservoir coupled to the vehicle body;
• and
• an electric machine coupled to the vehicle body and communicatively coupled to the power reservoir, the electric machine comprising:
• a rotor including one or more first segments including a first source of magnetomotive force (MMF) and one or more second segments coupled to the one or more first segments and including a second source of MMF that provides MMF in a direction that is parallel to the MMF provided by the first source.
