A method for manufacturing a rotor based on aluminum for electrical induction motors as well as such a rotor

摘要

A method for manufacturing a rotor (10), comprising that:a laminated cores steel stack (20) with a plurality of longitudinally directed slots; anda plurality of aluminum conductor rods (25) in the longitudinally directed slots is arranged, wherein the conductor bars (25) have first and second ends, which is composed of the longitudinally directed slots extend out;characterized in thatthe first and second ends of the conductor bars (25) under pressure with a pair of aluminum closure rings (15) are brought into contact; and the first and second ends of the conductor bars (25), the end rings (15) or both are made to vibrate, an oscillation of the friction welding point in order to form.
