In a method of operating an electrical drive system (10) that includes an electric motor (70), the electric motor (70) comprises an armature, which is mounted on a stator, and a rotor. Aligning the stator flux with the rotor flux enables 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 (10). The electric drive system (10) 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, for example, in heating the electric motor (70), for example for the purpose of de-icing. Again, the invention may enable the electric drive system (10) to carry full rated current yet produce little or no torque, thereby allowing the current to be used to generate heat in the motor (70). |
