Title
(DE) ELEKTRISCH ANGETRIEBENES ZWEIRAD
(EN) ELECTRICALLY DRIVEN TWO-WHEELED VEHICLE
(FR) VÉHICULE ÉLECTRIQUE À DEUX ROUES
Abstract
(DE)
Die Erfindung betrifft ein elektrisch angetriebenes Zweirad (1) mit wenigstens einer elektrischen Maschine (4), die einen achsfesten Stator (6) und einen felgenfesten Rotor (7) aufweist, wobei der Rotor (7) einen Rückschlussring (9) mit einer Vielzahl von daran über den Umfang verteilt angeordneten Permanentmagneten (8) aufweist. Es ist vorgesehen, dass der Rückschlussring (9) an seiner dem Stator (6) zugewandten Innenseite (11) Taschen (10) aufweist, in denen jeweils ein Permanentmagnet (8), insbesondere ein Ferrit-Magnet, zumindest im Wesentlichen angeordnet ist. Ferner betrifft die Erfindung ein Verfahren zum Ansteuern eines derartigen Zweirads.
(EN)
The invention relates to an electrically driven two-wheeled vehicle (1) comprising at least one electric machine (4) which has a stator (6) that is fixed to the axle and a rotor (7) that is fixed to the rim. The rotor (7) has a back iron ring (9) with a plurality of permanent magnets (8) which are distributed over the circumference of the back iron ring. The back iron ring (9) has pockets (10) on the back iron ring inner face (11) facing the stator (6), one permanent magnet (8), in particular a ferrite magnet, being at least substantially arranged in each said pocket. The invention further relates to a method for actuating such a two-wheeled vehicle.
(FR)
L'invention concerne un véhicule électrique à deux roues (1) comprenant au moins un moteur électrique (4) qui comporte un stator (4) solidaire de l'essieu et un rotor (7) solidaire de la jante. Le rotor (7) comporte une bague de retour de flux (9) munie d'une pluralité d'aimants permanents (8) répartis sur la circonférence. Selon l'invention, la bague de retour de flux (9) comporte, sur sa face intérieure (11) tournée vers le stator (6), des poches (10), dans chacune desquelles un aimant permanent (8), en particulier un aimant en ferrite, est au moins sensiblement agencé. L'invention concerne en outre un procédé permettant de commander un véhicule à deux roues de ce type.
