Abstract
A method for producing a rotor device, including providing a rotor shaft having at least one sheet metal packet joined to the rotor shaft. The at least one sheet metal packet includes magnetic units. The method includes performing a transfer molding process, in which the magnetic units are fixed in position in relation to the at least one sheet metal packet and at least one balancing disk is joined axially on the rotor shaft on at least one side of the at least one sheet metal packet such that a gap of a defined width is ensured between the at least one balancing disk and the at least one sheet metal packet. The gap is filled with a molding compound used for the transfer molding process. The method includes determining an imbalance of the rotor device and compensating the imbalance by removing material from the at least one balancing disk.
