Abstract
A turner gear assembly () for turning an unbalanced rotor of a wind turbine () having a drivetrain (). The turner gear assembly () includes a turner gear () configured to couple to the drivetrain () and having at least two motors (), and a valve block () connectable to the turner gear () and having a first flow control valve () configured to be in fluid communication with a pump () and with the at least two motors (). The first flow control valve () is selectively moveable between a first fluid control position () and a second fluid control position (). When the first flow control valve () is in the first fluid control position (), the at least two motors () operate in parallel and when the first flow control valve () is in the second fluid control position (), the at least two motors () operate in series. A method of operating the turner gear assembly is also disclosed.
