Title (EN) ELECTRIC DISC ROTOR WITH A PRESSURE REDUCER FOR THE MOTOR GAP
(FR) INDUIT ÉLECTRIQUE PLAT COMPRENANT UN RÉDUCTEUR DE PRESSION POUR ENTREFER DE MOTEUR
(DE) ELEKTRISCHER SCHEIBENLÄUFER MIT EINEM DRUCKREDUZIERER FÜR DEN MOTORSPALT
Abstract:
(EN) The invention relates to an electric disc motor comprising a rotor (10) which has an element (105) to be moved; and a stator (20) which is arranged relative to the rotor (10) such that a motor gap (30) is formed between the rotor (10) and the stator (20), wherein the electric disc motor is designed to convey a medium from a source region (90) to a target region (100) by means of the element (105) to be moved, and a target pressure in the target region (100) is higher than a source pressure in the source region (90). The electric disc motor additionally has a pressure reducer (140) for reducing a pressure acting on the rotor on the basis of the different pressures in the source region and in the target region. The pressure reducer is designed such that a pressure in the motor gap (30) is lower than the target pressure and greater than or equal to the source pressure.
(FR) Un moteur électrique plat comprend : un rotor (10) qui comporte un élément (105) à déplacer ; un stator (20) disposé par rapport au rotor (10) de manière à former un entrefer de moteur (30) entre le rotor (10) et le stator (20). Le moteur électrique plat est conçu pour transporter un milieu d’une zone source (90) dans une zone cible (100) à travers l’élément (105) à déplacer. La pression cible dans la zone cible (100) est supérieure à la pression source dans la zone source (90). Le moteur électrique plat comprend en outre un réducteur de pression (140) destiné à réduire la pression agissant sur le rotor en raison des différentes pressions dans la zone source et dans la zone cible. Le réducteur de pression est conçu de telle sorte que la pression dans l’entrefer de moteur (30) soit inférieure à la pression cible et supérieure ou égale à la pression source.
(DE) Ein elektrischer Scheibenmotor umfasst: einen Rotor (10), der ein zu bewegendes Element (105) aufweist; einen Stator (20), der so bezüglich des Rotors (10) angeordnet ist, dass ein Motorspalt (30) zwischen dem Rotor (10) und dem Stator (20) ausgebildet ist, wobei der elektrische Scheibenmotor ausgebildet ist, um durch das zu bewegende Element (105) ein Medium von einem Quellgebiet (90) in ein Zielgebiet (100) zu fördern, wobei ein Zieldruck in dem Zielgebiet (100) höher als ein Quelldruck in dem Quellgebiet (90) ist, und wobei der elektrische Scheibenmotor ferner einen Druckreduzierer (140) zum Reduzieren eines auf den Rotor wirkenden Drucks aufgrund der unterschiedlichen Drücke in dem Quellgebiet und in dem Zielgebiet aufweist, wobei der Druckreduziererer so ausgebildet ist, dass ein Druck in dem Motorspalt (30) kleiner als der Zieldruck und größer oder gleich dem Quelldruck ist.
