An electrical drive system includes an electric motor having an armature, which is mounted on a stator, and a rotor, wherein aligning stator flux with rotor flux enables current to flow in the armature without inducing torque on the rotor shaft. The disclosed operation may be used, for example, in testing the electrical drive system. The electric drive system can carry full rated current yet produce little or no torque, thereby increasing the current that can be tested during electrical drive test procedures without producing undesired forces or motion. The method may be used, for example, in heating the electric motor, for example for de-icing.
