  • Linear actuator or generator with rods
    Patent number: 7372178
    Abstract: The invention concerns an electrical machine, whereof the active part includes a global solenoid winding (110, 210, 310) for each phase and includes, inside said winding(s), a stack of ferromagnetic or non-magnetic parts (400) and magnetized parts (500), the ferromagnetic or non-magnetic parts being provided with passages traversed each by at least one relatively sliding element (600), each sliding element constituting a succession of portions alternately magnetic (620) and non-magnetic (630), the passages formed in the ferromagnetic or non-magnetic parts of the stack forming orifices whereof the internal cross-section encloses each time one sliding element, the sliding elements (600) consisting in rods having each an outer periphery matching the internal cross-section of the traversed orifices.
