技術名稱: 永磁式轉子與永磁式轉動構件

技術簡介

一種永磁式轉子包含一轉子鐵心、多個永久磁鐵及一非磁性外固定環。轉子鐵心具導磁性,並具有一外表面及自外表面向內凹陷之多個鳩尾槽。這些永久磁鐵分別卡合於這些鳩尾槽。非磁性外固定環套設於轉子鐵心,並將這些永久磁鐵環繞於內。其中,非磁性外固定環不具導磁性。

Abstract

A rotor for permanent magnet includes a rotor core, many permanent magnets and a nonmagnetic fixing ring. The rotor core has a magnetic conductivity and has an outer surface and many dovetail grooves locating at the outer surface. The permanent magnets lock in the dovetail grooves respectively. The nonmagnetic fixing ring circus the rotor core and the permanent magnets. The nonmagnetic fixing ring doesn’t have magnetic conductivity.

技術規格

永磁馬達轉子的轉速範圍在10,000rpm ~30,000rpm。

Technical Specification

Permanent magnet motor rotor speed range of 10,000rpm~30,000rpm。

技術特色

分段式永磁轉子設計,將分段式轉子磁鐵做最佳化的角度錯開,可降低馬達頓轉轉矩及馬達脈動漣波轉矩,並提升馬達效率性能。
