<p>An induction module for an asynchronous linear electric motor, including an outer protective shell (7), a laminated magnetic circuit consisting of a bar (8) supporting field coils (13, 14) housed in recesses (9) in the magnetic bar (8), and an insulating material (15) filling the empty space inside the protective shell (7) between said protective shell and the magnetic bar (8) with the coils thereon. To facilitate the production of said induction module and reduce its cost price, the magnetic bar (8) extends higher than the longitudinal (5) and transverse (6) walls of the protective shell (7), whereby, once the insulating material (15) has been cast, the planar polar surfaces (8b) of the projections (11) of the magnetic bar extend outwardly of the block of solidified insulating material (15).</p> |
