The paper presents the energy saving potential of induction machines by using variable rotor flux instead of commonly used constant flux. The efficiency optimized rotor flux depends on the actual load and speed of the motor. At low load it has to be decreased with reference to a pre-calculated lookup table. This table can be included in a field oriented speed control structure as reference value of...
Because it does not participate in the vehicle traction, the thermal energy is not highlighted in the electric and hybrid electric vehicle (EV and HEV) study, especially for electrical components like electric machines and batteries. Nevertheless, the thermal states of these components can have a great impact on the vehicle behaviour, such as safety, performances and autonomy, etc. This impact is...
