Abstract
The invention concerns an electrical machine, whereof the active part includes a global solenoid winding () for each phase and includes, inside said winding(s), a stack of ferromagnetic or non-magnetic parts () and magnetized parts (), the ferromagnetic or non-magnetic parts being provided with passages traversed each by at least one relatively sliding element (), each sliding element constituting a succession of portions alternately magnetic () and non-magnetic (), 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 () consisting in rods having each an outer periphery matching the internal cross-section of the traversed orifices.
