Abstract
Methods and apparatus for controlling performance of electric motors in a system having two or more electric motors, the motors adapted for being coupled to two or more wheels of an electric vehicle, each of the electric motors having armature and field coils which are independently excited by a source of voltage to generate armature and field currents, the armatures being connected in series to the voltage source include detecting a condition in the system indicating that one of the wheels is slipping, reducing power delivered to one of the motors that is associated with the slipping wheel in response to the detection of the condition, providing power to the one or more motors that are not associated with the slipping wheel after the power delivered to the motor associated with the slipping wheel is reduced, and restoring the power delivered to the one of the motors associated with the slipping wheel in response to a recovery event.
