1. An electrical system configured to control an electrically-excited electric motor, comprising:
an inverter configured to supply alternating current (AC) electrical power to the electrically-excited electric motor;
the electrically-excited electric motor, comprising:
a rotor having a rotor winding; and
a stator having a stator winding;
wherein, the stator winding is electrically connected to the inverter and the rotor winding is electrically connected to the inverter such that the stator winding receives an electrical current from the inverter and the inverter supplies direct current (DC) electrical current to the rotor winding.
