An enclosure arrangement with mutually detachable elements, for supporting and protecting a preset series of electric motors provided with a shaft, electric connectors, leads, supporting bearings and having different heights and thicknesses of magnetic lamination packs thereof, the enclosure arrangement comprising: two half-shells comprising a front half-shell and a rear half-shell, shaped as domes having a substantially ellipsoidal shape and provided with mutually opposite identical cavities and with opposite ends that have different depths; a flat rectangular band associated with a peripheral edge of the front half-shell, said band protruding from said edge and being interrupted in a central part thereof in order to leave exposed the lamination pack enclosed between the two half-shells, thereby forming two mutually opposite band portions; protruding ends of the rear shell, protruding from an edge thereof for insertion under said band portions of the front edge, so as to allow abutting of the edge of the rear half-shell against the peripheral edge of the front half-shell provided with said band portions, upon accommodation of lamination packs, between the two half-shells, which have a minimum height, and so as to further allow the rear half-shell to move away, with respect to the front half-shell, to accommodate lamination packs having heights varying from the minimum height up to a maximum height of the preset series of motors; anchoring means, provided on at least one of said half-shells for anchoring the motor, enclosed and locked within the enclosure arrangement, to a user device; seats for providing passage of the motor shaft and of the electric connectors outside the enclosure arrangement, to the leads of the motor; and bearing seats for the motor bearings or other bearings that support the rotor.
