Electric motor having a frame structure without any screws

摘要

The invention relates to an electric motor having a frame structure without any screws and having a stator, a rotor and two bearing plates which are used to guide the rotor and are held together by supporting elements (11), subject to tensile stress. Low-vibration supporting elements (11) of high strength and thus high stiffness are produced in that those parts of the supporting elements (11) which are arranged between the bearing plates each have a longitudinal web (77) with laterally integrally formed side limbs (71, 73) which are connected to one another in a positively locking manner in order to form closed cavities (74). <IMAGE>
