Abstract

Un motor eléctrico para ascensores y similares, comprende un estátor (3) con bobinas eléctricas dispuestas a lo largo de la superficie sustancialmente cilíndrica, y un rotor (11) montado de forma rotatoria respecto al estátor (3), con una pared cilíndrica asomada a la superficie sustancialmente cilíndrica del estátor. En la pared sustancialmente cilíndrica del rotor (11) están fijados los imanes permanentes (21, 21') que están distanciados de un entrehierro de la superficie sustancialmente cilíndrica del rotor (11). Los imanes permanentes (21, 21') están fijados a la pared sustancialmente cilíndrica del rotor (11) mediante acoplamiento de forma por ejemplo a cola de milano.An electric motor for elevators and the like comprises a stator (3) with electric coils arranged along the substantially cylindrical surface, and a rotor (11) rotatably mounted with respect to the stator (3), with a cylindrical wall facing the substantially cylindrical surface of the stator. On the substantially cylindrical wall of the rotor (11) are fixed permanent magnets (21, 21 ') that are distanced from an air gap of the substantially cylindrical surface of the rotor (11). The permanent magnets (21, 21 ') are fixed to the substantially cylindrical wall of the rotor (11) by coupling, for example, to dovetails.
