Description
本發明係有關一種永磁馬達軸心磁鐵固定裝置,尤指一種將磁鐵緊密包覆,使其不會因高速旋轉而脫落,進而提高馬達使用壽命之永磁馬達軸心磁鐵固定裝置。 The invention relates to a permanent magnet motor shaft magnet fixing device, in particular to a permanent magnet motor shaft magnet fixing device which tightly coats a magnet so as not to fall off due to high speed rotation, thereby improving the service life of the motor.
按;一般之永磁馬達基於設計的差異,雖其結構上有所不同,惟大多存在磁鐵高速脫落時造成脫落之缺失,其原因係為: According to the difference in design of the general permanent magnet motor, although the structure is different, most of them have the loss of falling off when the magnet is detached at high speed. The reason is:
1.磁鐵的嵌入效率較差,因外部為鐵會造成磁力阻礙。 1. The embedding efficiency of the magnet is poor, and the magnetic force is hindered by the external iron.
2.以玻璃纖維包覆方式,因玻璃纖維容易破裂,造成馬達毀損。 2. In the case of glass fiber coating, the glass fiber is easily broken and the motor is damaged.
3.以圓形白鐵包覆,同樣會造成鬆脫,造成馬達毀損。 3. Covering with a round white iron will also cause looseness and damage the motor.
