The effect of excitation angles in single-pulse controlled switched reluctance machines on acoustics and efficiency

To make the development process of electric machines more efficient, it is very important to assess the characteristics of a given machine design early in the design process. In the case of a Switched Reluctance Machine in single-pulse operation, the efficiency is mainly determined by the turn-on and turn-off angle. These parameters on the other hand have a significant impact on the acoustic behavior of the drive system. This paper compares different sets of excitation angles and investigates the validity of a late-single-pulse strategy for Switched Reluctance Machines in generator mode. Measurements confirm partly this control strategy and the underlying simplified simulation approach for the examined machine.
