Abstract (en)
[origin: EP1253226A1] The structure comprises a driving shaft (9) and an associated movable core (8), which linearly moves within a cavity of a stator housing (2) bearing excitation coils (6-7) and guide/supporting bushes (10) for the driving shaft. The latter is provided with a projecting central collar (9a) integral with the shaft, onto which the movable core (8) of the motor is crimped by means of two identical core portions (11a, 11b), made of a non-magnetic material, and provided with respective threaded areas and terminal flanges (110a, 110b), and mounted on the driving shaft (9) on opposite sides of the projecting collar (9a). The core portions (11a, 11b) are mutually connected through a threaded, cylindrical central case (15) which pushes the terminal flanges (110a-b) of the core portions axially into abutment with corresponding, radial-polarity magnetic rings (16a, 16b). <IMAGE>
