## What are the two types of static Scherbius system?

Sub-synchronous Generating – For sub-synchronous speed, the torque is required to be positive, although the slip is positive. The power is fed into the rotor through the slip ring. Super-synchronous Generating – When the speed of the motor above the synchronous speed, then the slip and torque becomes negative.
