Abstract

An electric working machine is provided, comprising: a groove defined by a rotor hub, the groove being inclined relative to an axis of rotation; a first stack of first laminations mounted on the rotor hub, each of the first laminations containing first tabs inserted into the groove, and the interaction between the first tabs at opposite ends of the first stack and the groove restricting the movement of the first stack relative to the rotor hub; several first magnets mounted on the first stack; a second stack of second laminations mounted on the rotor hub, each of the second laminations containing second tabs inserted into the groove, and the interaction between the second tabs at opposite ends of the second stack and the groove restricting the movement of the second stack relative to the rotor hub;and several second magnets mounted on the second stack. The several first and second magnets are inclined relative to each other.
