1. A gymnastic machine comprising
a base structure having a front transmission assembly and a rear transmission assembly, wherein said base structure comprises two lateral longitudinal members between which a sliding belt slides,
the sliding belt, associated to said base structure, configured for a user to perform a gymnastic exercise, wherein said sliding belt is configured to rotate by means of said front transmission assembly and said rear transmission assembly according to a sliding direction, wherein said sliding belt is arranged between said two lateral longitudinal members; and
an electric motor, having at least one stator and at least one rotor, said electric motor being kinematically coupled to said front transmission assembly, or to said rear transmission assembly, for moving said sliding belt,
wherein said electric motor is of axial flow type, wherein a magnetic field flow is directed to be parallel with respect to an axis of the electric motor,
wherein said at least one rotor is provided with a smooth portion and a toothed portion for coupling with said sliding belt.
