A three phase inverter circuit designed for controlling an AC motor is used to control the current through the armature winding and field winding of a DC series motor. A DC series motor has a first current supply to the armature 4 of the motor and a second current supply to the field winding 6. A controller is configured to control the current through one of the armature and field winding based on the respective other one of the current through one of the armature and field winding. A three phase inverter may be used to control a DC series motor provided with only three terminals. The armature may be coupled between the first and second node of the inverter, and the field winding may be coupled between the second and third nodes. The controller may also control the current through the armature and field winding of the motor, where the armature current is based on a required output torque. The first and second current supplies may be configured to be controlled independently.
