摘要:
Disclosed is a method of manufacturing a rotor shaft including a rotor (12) and a shaft (11) having a groove (11b) formed on a periphery to open radially outwardly, the rotor (12) being fixed to the shaft (11) through a caulking plate (13) disposed on the periphery of the shaft (11) and adjacent the rotor (12) in an axial direction thereof. This method comprises the step of caulking the caulking plate (13) to fix the rotor (12) to the shaft (11) by applying a load to an end portion of the caulking plate (13) from outside in a radial direction, opposite the groove (11b), when the caulking plate (13) is disposed in the predetermined place, causing a part of the caulking plate (13) to be press-fitted into the groove (11b). This caulking and fixing step includes pressing a punch (14) against the caulking plate (13) from outside in a radial direction of the shaft (11), thereby fixing the rotor (12) to the shaft (11).

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.

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.

The invention relates to a rotor (10) with a rotor spider (11) which rotates about an axis, comprising a number of webs (12) and a laminated rim (14), made from individual rim sheets (16), concentrically surrounding the rotor spider (11) and connected to the rotor spider (11), by means of taper keys (13) in a laminated rim keyway. A simplified connection of laminated rim (14) to rotor spider (11) is achieved, whereby the keys (13) and the laminated sheets (16) are embodied such as to engage by forming a rigid positive fit.
