Calculate the per-phase current that has to be carried by the cables to the power electronics converter and the step-up transformer located at the base of the tower.

Presented virtual models have been of various complexity - the simpler ones enable virtual analysis of electrical machines and more complex virtual models also deal with algorithms for synthesis of drive controllers. The DC drive controllers in the frequency domain are calculated mostly by using the following criteria:. During intervals with a constant speed, no torque is required. In practice, coupling mofeling are often used for the following reasons: A rotary motor is driving a load that requires linear motion The motors are designed to operate at higher rotational speeds to reduce andd physical size compared to the speeds required of the mechanical loads The axis of rotation needs to be changed There are various types of coupling mechanisms.
