Technical field
This utility model relates to technical field of motor manufacture, is specifically related to a kind of direct-drive permanent-magnetism motor rotor magnetic steel press mounting structure.
Background technology
Current direct-drive permanent-magnetism motor quickly grows, the fixing means of magnet steel, is usually and is holed by magnet steel, is screwed on rotor field spider cylindrical, but this mode complicated operation, the damage of magnet steel is bigger.
Utility model content
For the technical problem existed in background technology, this utility model purpose is to provide a kind of direct-drive permanent-magnetism motor rotor magnetic steel press mounting structure, and simple in construction is easy to operate and the damage of magnet steel is less.
For realizing above-mentioned technical purpose, this utility model adopts the following technical scheme that and is achieved.
A kind of direct-drive permanent-magnetism motor rotor magnetic steel press mounting structure, including rotor field spider, the outer surface of rotor field spider is along the bonding multiple row magnet steel in its circumferencial direction interval, it is provided with press strip between adjacent column magnet steel, two step side of press strip are pressed in each step side of its both sides magnet steel, and the first securing member is fastenedly connected press strip and rotor field spider；Rotor field spider has the first end and the second end, described first end is provided with a boss, each column magnet steel abuts described boss near that magnet steel of the first end, by the fixing end plate of the second securing member on described second end, each column magnet steel abuts described end plate near that magnet steel of the second end.
As preferably, the height of described boss is 3mm.
As preferably, multiple row magnet steel is pasted on rotor field spider by structure glue.
As preferably, gluing on multiple row magnet steel outer surface, and wrap up alkali-free glass fiber cloth.
As preferably, described boss is formed by the outwardly extension of rotor field spider.
The beneficial effects of the utility model:
Adopting this press mounting structure, magnet steel, without boring, reduces processing and mounting process, is fixed magnet steel, reasonable stress by press strip diametrically, damage little, axially fixes magnet steel by boss and end plate, simple in construction, reliably.
