It is provided with the reflection code disk matched with read head.
The further motor shaft is single side axis, and single side axis does not pass through inner cover.
The further motor shaft is bilateral axis, and interior cover offers through-hole, and the bilateral axis passes through inner cover
Through-hole is provided with sealing framework between inner cover and bilateral axis.
The further inner cover and external ring lid are integrally formed.
The further inner cover and external ring lid split settings, inner cover and external ring lid junction are provided with sealing strip.
Compared with prior art, the utility model has the beneficial effects that contaminated in entire anti-read head and reflection code disk
Hub motor form a sealing space using bearing support block and end cap, the wiring board for carrying read head is fixed on bearing support
On seat, make read head and reflection code disk far from winding, first can avoid high temperature and deformation occurs, make read head keep initial position,
It avoids run-off the straight and leads to not be directed at reflection code disk, the volatile matter that secondly winding generates at work is isolated, can not
Into in sealing space, volatile matter is avoided to be attached to reflection code disk and read head surface, guarantees working performance.

Specific embodiment
The embodiment of the anti-read head of the utility model and the contaminated hub motor of reflection code disk is done further referring to Fig.1
Explanation.
A kind of anti-read head and the contaminated hub motor of reflection code disk, including motor shaft 4, stator 2, rotor 3 and end cap
5, winding 1 is provided on stator 2, stator 2 is fixed on the motor shaft (4), and rotor 3 is located at the outer ring of stator 2, and the end cap 5 includes
External ring lid 52 and inner cover 51, the external ring lid 52 are located at the outer ring of inner cover 51, are provided with bearing support block 6 on the motor shaft 4,
It is provided with bearing 11 between the bearing support block 6 and external ring lid 52, forms sealing between the inner cover 51 and bearing support block 6
