    摘要: An electric motor includes a stator, at least one rotor, an output shaft engaged with the at least one rotor, and a contact area changing device configured to change an area of contact between the at least one rotor and the output shaft, wherein the area of contact between the at least one rotor and the output shaft affects a characteristic resonant frequency of the at least one rotor. A method to reduce vibrations in an electric motor includes engaging an output shaft into at least one rotor, rotating the output shaft and the at least one rotor with respect to a stator, changing an area of contact between the at least one rotor and a radial protrusion of the output shaft, and shifting the resonant frequency of the at least one rotor with the changed area of contact.

    摘要: The present invention relates to a generic electric motor, in which the laminated pack is made with a geometry such as to reduce the amount of metal off-cuts to a minimum.
    Said motor has a rotor obtained by stamping two distinct identical parts (10), designed to he assembled in such a way as to enable their mutual connection. Accommodated inside a slot (32) is a drive member (40), which in turn houses a drive shaft (50). The particular conformation of the two identical parts enables maximum compacting of the figures on the strip or sheet of metal that is stamped.
