The thermal energy consumption of rotor windings is reduced, motor service life is extended, energy-saving effect is prominent.
But in the actual production process, it between permanent magnet and iron core, is bonded by glue, under motor low-speed situations,
Glue bonding can be used normally, or the long period can be used, but under motor high-speed case, specifically be greater than
When 3500 revs/min, for glue under the effect of huge centrifugal force, while in the case of a high temperature, glue failure leads to permanent magnet
It falls, so that magneto breaks down.
