Abstract
The system () is used for starting and synchronizing synchronous motors () with power electricity of an electric grid (). The system () includes a variable frequency driver () for starting the synchronous motors (), and an electrical diverter () for each synchronous motor (). The electrical diverter () has a control input electrically coupled to a control output of the variable frequency driver () so to selectively couple stator windings () of synchronous motors () with a power output () of the variable frequency driver () or with the electric grid () based on signals that are received at a control input of the variable frequency driver () and represent a position of the shafts of the synchronous motors (). Therefore, switching occurs at desired shafts positions.
