An electrical drive system 10 includes an electric motor 70 comprising an armature, which is mounted on a stator, and a rotor. The stator flux is aligned with the rotor flux to enable current to flow in the armature without inducing torque on the rotor shaft 80. The method 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, compared with prior-art procedures. The method may be used in heating the electric motor for example for the purpose of de-icing as it enable the electric drive system to carry full rated current yet produce little or no torque, thereby allowing the current to be used to generate heat in the motor. |
