Abstract

"ROTORES UTILIZANDO INCLINAçãO ESCALONADA". Rotores R de ímã dividido tendo uma parte inclinada escalonada ao invés de uma parte helicoidal são descritos. A parte inclinada escalonada permite o uso de seções de ímã reto (44) que podem ser inseridas nos entalhes do núcleo do rotor (38), eliminando, assim, a necessidade de produzir uma hélice a partir da gaiola do rotor. A parte inclinada escalonada é eficaz para desacoplar a harmónica da ordem da fenda do estator. Além disso, a inclinação escalonada R inclui, em algumas modalidades, fendas abertas (22), de modo que o rotor não seja submetido à saturação da ponte do rotor."ROTORS USING STAGED TILT". Split magnet R rotors having a stepped inclined part rather than a helical part are described. The stepped inclined portion allows the use of straight magnet sections (44) that can be inserted into the rotor core notches (38), thus eliminating the need to produce a propeller from the rotor cage. The stepped inclined portion is effective for decoupling the harmonic from the stator slot order. In addition, the stepped slope R includes in some embodiments open slots 22 so that the rotor is not subjected to saturation of the rotor bridge.
