Patent

CA 2580897

The invention relates to a generator/electric motor, in particular for wind power plants, cable controlled plants or for hydraulic plants comprising a bearing, an annular stator (3) fixed to the bearing, an annular rotor (2) rotatable with respect to said stator (3), actuating means connected to the rotor (2) and permanent magnets and windings placed on opposite surfaces of the stator (3) and the rotor (2), respectively. According to said invention, the rotor (2) and/or the stator (3) are subdivided in the axial direction in different sectors into segments (4, 5) which are in contact and accessible in such a way that it makes it possible to introduce or remove the sector (4, 5) in the axial direction or the sector (4, 5) is provided with an orifice enabling the access to the windings (6) and/or to the permanent magnets (7).

L'invention concerne un générateur/moteur électrique à utiliser notamment dans des centrales éoliennes, des installations à commande par câble ou des centrales hydrauliques. Ce générateur/moteur électrique comprend un palier, un stator annulaire (3) solidement fixé au palier, un rotor annulaire (2) tournant par rapport au stator (3) et des moyens de commande liés au rotor (2), des aimants permanents et des enroulements qui sont respectivement placés sur des surfaces opposées du stator (3) et du rotor (2). Selon l'invention, le rotor (2) et/ou le stator (3) sont subdivisés dans la direction axiale dans différents secteurs en segments (4;5) qui sont en contact et accessibles avec la possibilité d'introduire ou d'extraire dans la direction axiale un secteur (4;5) ou bien un secteur (4;5) est pourvu d'un orifice permettant l'accès aux enroulements (6) et/ou aux aimants permanents (7).
