Title
(EN) A VERNIER PERMANENT MAGNET LINEAR GENERATOR
(FR) GÉNÉRATEUR LINÉAIRE À AIMANTS PERMANENTS VERNIER
Abstract
(EN)
A Vernier permanent magnet linear generator employs a translator (50) having a plurality of translator modules (55) oriented in a vertical array. At least a portion of the plurality of translator modules has permanent magnets (65). Supports (66) at lateral edges of the plurality of translator modules and a rod (36) connected to the supports attach the translator to a driving element (12). The driving element reciprocating the translator in a longitudinal direction. Two stators (52) are supported on a reaction body (16) oppositely spaced from the vertical array of translator modules by an air gap and offset by one half slot pitch. The stators have three phase integral-slot stator windings magnetically interacting with a magnetic field induced by the permanent magnets. A slot depth of the stators is configured such that an 11th harmonic component of the magnetic field is saturated at a multiple value of a 1st harmonic component.

L'invention concerne un générateur linéaire à aimants permanents Vernier qui utilise un translateur (50) muni d'une pluralité de modules de translation (55) orientés dans un réseau vertical. Au moins une partie de la pluralité de modules de translation comporte des aimants permanents (65). Des supports (66) au niveau des bords latéraux de la pluralité de modules de translation et une tige (36) reliée aux supports fixent le translateur à un élément d'entraînement (12). L'élément d'entraînement confère un mouvement de va-et-vient au translateur dans une direction longitudinale. Deux stators (52) sont supportés sur un corps de réaction (16) espacé de manière opposée du réseau vertical de modules de translation par un entrefer et décalés par un pas de demi-fente. Les stators comportent trois enroulements de stator à fente intégrale de phase interagissant magnétiquement avec un champ magnétique induit par les aimants permanents. Une profondeur de fente des stators est conçue de telle sorte qu'une 11e composante harmonique du champ magnétique est saturée à une valeur multiple d'une 1re composante harmonique.
