LINEAR ELECTRIC MOTOR WITH AN ARRANGEMENT FOR REDUCING VIBRATIONS

摘要

A linear electric motor is composed of a tubular stator element (2) referable to a respective longitudinal axis (A), equipped with a predetermined number of ferromagnetic elements (3) and a set of windings (4) centred on the axis (A), also a rod (5) inserted through the stator element (2) and presenting a given number of permanent magnets (6) designed to establish a state of equilibrium in which the rod (5) remains motionless, and at least one state of non-equilibrium in which the rod (5) shifts along the longitudinal axis (A). The motor (1) also includes an auxiliary ferromagnetic element (10), positioned at a first end (5a) of the rod (5) projecting from the tubular stator element (2), such as will counteract the magnetic interaction between the permanent magnets (6) and the ferromagnetic elements (3).
