Abstract
A motorised roller comprises a central shaft (12) defining a stator (2) arranged axially and exhibiting a plurality of windings, a cylindrical cover (13) defining a rotor (3) arranged about the stator (2) and exhibiting a plurality of permanent magnets, at least a fixing shaft (8) projecting axially from an end (1b) of said motorised roller (1), in order to constrain the motorised roper (1) to an external support structure (7), a connector (9) for connecting the shaft (12) of the stator (2) to the fixing shaft (8), and an elastic joint (14) interposed between the shaft (12) of the stator (2) and the fixing shaft (8) which enables a relative decoupling movement between the fixing shaft (8) and the shaft (12) of the said stator (2).
