A method can be used to control an electric motor-generator in order to avoid demagnetization of the permanent magnets in the electric motor-generator. The method includes the following steps: (a) receiving, via a control module, a torque command input; (b) determining, via the control module, an available torque of the electric motor-generator based, at least in part, on a rotor temperature and a magnitude of an electric current in the stator; (c) determining, via the control module, a torque command based, at least in part, on the available torque and the torque command input; and (d) commanding, via the control module, the electric motor-generator to generate torque in accordance with the torque command in order to avoid demagnetization of the permanent magnets.
