The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of grating encoding on curtain motor
Device, including base, the side of the base are provided with shell；The shell is internally provided with connecting shaft；The connecting shaft
Side is light source；Grating encoding wheel described in the inner ring clamping that the top of the connecting shaft passes through grating encoding wheel；The grating is compiled
Grating is provided with code wheel；The side connection baffle plate of the grating encoding wheel；The side connection photodetector of the baffle plate；It is described
The side connection circuit board of photodetector.
Preferably, in order that the round and smooth degree and precision of base are higher, the surrounding of the base is in arc-shaped structure.
Preferably, in order that grating encoder integrally facilitates connection rolling motor, the surrounding upper end of the base is provided with
Round tube hole.
Preferably, in order that lighting effect reaches most preferably, the light source is light emitting diode.
Preferably, in order that connecting shaft is more firm in the connection of inner ring, the inner ring is provided with square groove.
Preferably, in order that control accuracy is high, the quantity of the grating is 32.
The beneficial effects of the utility model are：The grating encoding wheel of the grating encoder that this kind is used on curtain motor can be with
32 grating encodings of pole are easily done, and control accuracy is high, production gets up simple, and the surrounding of base is arc-shaped structure,
Improve the rounding of base outer ring, it is ensured that overall precision, light emitting diode has good illumination effect so that light is examined
Surveying device can sensitively detect very much, and this grating encoder on curtain motor is believed using the photodetector of encoder
Whether the Grating examinations that number can pass through grating encoding wheel judge the steering of motor, rotating speed and position to light source, enable motor smart
The speed that really position of control curtain and curtain are moved, and installation operation is convenient, firm and durable.
