A two-phase synchronous electric motor, comprising a permanent-magnet rotor rotating around a rotation axis, and a core lamination pack stator. First and second pairs of pole pieces define: a housing/rotation seat for the rotor. Each pole piece comprises a core, having an end associated to the core lamination pack, a free end portion facing the rotor housing/rotation seat, and a coil. The free end portion of the core of each pole piece comprises a core lamination pack extending in parallel planes to the rotation axis of the rotor. The core laminations have a variable length to form a surface of the free end portion of the core of each pole piece that is concave in the axial direction and partially wraps the rotor. A coupling between the rotor and a load is through a motion transmission joint having driving and driven elements associated in a kinematic series.
