How to change the Rotation Direction and Wire Configuration – Star …
The direction of rotation for the motor shaft of an AC motor is defined in IEC 60034-8 as either CW (clockwise) or CCW (counter-clockwise), when looking into the motor shaft. The direction of rotation of a three-phase AC motor can be changed at the terminal box. This is done by interchanging two of the line cables, e.g switch L1 and L2.
5 · The Siemens Energy synchronous condenser solution comprises a horizontal synchronous generator connected to the high-voltage transmission network via a step-up transformer. It is started up and stopped with a frequency-controlled electric motor (pony motor) or a starting frequency converter.
