Abstract
A system is provided for controlling an electric machine. The system has a power source configured to supply electric energy to the electric machine. In addition, the system has an inverter operationally connected to the power source and the electric machine and configured to increase or decrease a rotor flux component of a voltage applied to the electric machine, while maintaining a torque component at an essentially constant level. The system further has a control device configured to determine at least one parameter of the electric machine and operate the inverter in either a first or a second mode in response to the at least one determined parameter.
