Description
Technical field
The utility model relates to a kind of scrambler, specifically discloses a kind of magneto-electric absolute value encoder.
Background technology
Scrambler is a kind of equipment position signalling being converted into digital signal, absolute value encoder is the scrambler after power-off with position memory ability, in actual applications, the precision of scrambler and resolution are key problem in technology, precision and resolution height determine its in different technologies field, the application of different technologies industry.
Utility model content
Goal of the invention of the present utility model is: provide for overcoming the above problems the magneto-electric absolute value encoder that a kind of precision is high and resolution is high and cheap.
The technical scheme that the utility model adopts is such:
A kind of magneto-electric absolute value encoder, comprise PCB, sinusoidal magnetic field induction chip, circular magnet steel, some transmission shafts, some gears, described transmission shaft comprises main shaft, the first transmission shaft, second driving shaft, the 3rd transmission shaft, by described gear connection for transmission between described transmission shaft; Being provided with described circular magnet steel at described main shaft and described 3rd transmission shaft with one end, just sinusoidal magnetic field induction chip being provided with, for detecting sinusoidal magnetic field position to described circular magnet steel end face; Described sinusoidal magnetic field induction chip is arranged in PCB.
Further, described gear comprises 8 gears and 64 gears.
Further, coaxially be connected with 8 gears with described main shaft, it engages with 64 gears be arranged on described first transmission shaft, on the first transmission shaft, with 64 gears, be coaxially arranged with 8 gears, 8 gears and 64 gears alternately, drive to the 3rd transmission shaft through three grades.
In sum, owing to adopting technique scheme, the beneficial effects of the utility model are:
The utility model adopts sinusoidal magnetic field induction chip, and can detect sinusoidal magnetic field position, also namely can detect the circumferential position of the transmission shaft coaxial with circular magnet steel, precision reaches 2
12get 10 precision, i.e. circumference resolution 360/1024=0.35 °, take turns cascade due to this carrying out 3 grades of 8:1 to slow down, main shaft is 512:1 to the total reduction ratio of 3rd level transmission shaft, and therefore main shaft rotates 512 circles, and 3rd level transmission shaft rotates 1 circle, the locator data of enclosing scope 2 sinusoidal magnetic field induction chips outputs at main shaft 512 can not be overlapping, so scrambler is 2
20resolution absolute value encoder.
Because magnetic induction chip is low-power consumption analog-digital hybrid circuit, so low in energy consumption, precision is high, adopt single-chip microcomputer to carry out signals collecting, coded format is changed, and software carries out frame hopping and suppresses process, multiple interfaces signal can be made easily export, comprise SSI, SPI, CAN, RS485, RS232, PWM, analog voltage, 4-20mA etc.
Accompanying drawing explanation
