Summary:The general strategy to get a very fast torque control in a DC or AC machine is based on keeping the pulsational electromotive forces (EMFs) of all of its phases as small as possible during the transient states and achieving the torque changes by exclusively enhancing the rotational EMFs. All the resources available have to be oriented in this direction. This very simple but profound physical idea, when applied to DC or AC machines, allows the different control methods for these machines that have been developed to date and regarded as the best from a dynamic point of view to be deduced in a unified, systematic, and straightforward way.
