Linear motor ( 10 ) comprising a rotor ( 13 ), having a plurality of teeth ( 21, 22 ), wherein each pair of adjacent teeth ( 21, 22 ) defines a corresponding compartment ( 23 ) inside which at least a relative electric coil ( 24 ) is housed. The linear motor ( 10 ) also comprises a support ( 18 ) on which a plurality of permanent magnets ( 19 ) are assembled, disposed in use facing the electric coils ( 24 ). The rotor is defined by one or more modular elements ( 14 ) each of which comprises two external teeth ( 21 ) and one or more intermediate teeth ( 22 ). Each external tooth ( 21 ) has a thickness (s') substantially equal to about half the thickness (s) of each intermediate tooth ( 22 ), so that, when two external teeth ( 21 ), belonging to two respective modular elements ( 14 ), are put adjacent, the resulting tooth has a thickness substantially equal to the thickness (s) of each of the intermediate teeth ( 22 ).
