Abstract:
A rotor disk for an electric motor including a shaft hole for receiving a shaft of the electric motor, a set of positioning holes around the shaft hole, each configured to receive a positioning pin. The shaft hole and the set of positioning holes are positioned in the rotor disk such that when the rotor disk is set to a rotated position with respect to another similar rotor disk, and the shaft and the positioning pins are penetrated to the respective holes of the two rotor disks, the disks cause a pressing force to the shaft.
