Description
Technical field
Motor device field is the utility model is related to, specially a kind of novel waterproof motor rotor.
Background technology
At present, the waterproof ability of most of external rotor electric machine is poor on the market, the fitted seal between outer rotor and stator
It is not good enough, it is difficult to which that satisfaction uses in relatively rugged environment.When the use environment of external rotor electric machine is that outdoor or moisture is more
Interior when, the gap that water is easy between outer rotor and the plastic packaging end plate of stator is entered inside external rotor electric machine, is caused
External rotor electric machine damages or the lost of life.If if external rotor electric machine is axially horizontal positioned, the ability of waterproof can be worse.
Utility model content
The purpose of this utility model is to provide a kind of novel waterproof motor rotor, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of novel waterproof motor rotor, including turn
Axle, rotor core, magnet steel, sheath and sleeve, the rotating shaft are arranged in sleeve, and the rotor core is socketed in rotating shaft, institute
State sheath and be arranged to two, the sheath is socketed in rotating shaft, and two sheaths are located at the both sides of rotor core, the shield respectively
The side of set contacts with rotor core, and the magnet steel is arranged to four, and four magnet steel are in rectangular configuration is arranged on the interior of sleeve
Portion.
Preferably, the sheath by for opening and while formed for the cirque structure remained silent, the sheath is closes
Mouthful one side contacted with rotor core, the position of the sheath and shaft contacts connects using laser welding mode, the sheath and
The position of barrel contacts is connected using laser welding mode.
Preferably, the rotor core is provided with magnet steel slot, and the magnet steel is plugged in magnet steel slot.
Preferably, the both sides of the magnet steel are provided with asphalt mixtures modified by epoxy resin fat pad, and the section of the asphalt mixtures modified by epoxy resin fat pad is arranged to triangle.
Preferably, through hole is provided with inside the rotating shaft, the through hole runs through rotating shaft, and the axis of through hole and the axis of rotating shaft
On same straight line.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is reasonable in design, instrument can need to be used to confirm whether magnet steel polarity is wrong, together before welding
When need to use laser welding between sheath and sleeve, sheath and rotating shaft, can ensure welding after rotor assembly degree of protection
For IP68, waterproof ability is stronger, and assembling finishes post-equalization dynamic balancing, can ensure the amount of unbalance at rotor assembly both ends≤
150mg。
