Semiconductor Magnetoresistive Element Composition
MS0083 generates differential A+/A-,B+/B- phase analog output voltages by combining module m=0.8 gear and bias magnet.
FEATURE
□ Design optimized for 64 to 128 teeth gears of m=0.8
➢ In B=0T, R3<R1, R2<R4 (R7<R5, R6<R8), offset voltage is
decrease combining gear and bias magnet
□ Outputs of analog voltage of ideal sine/cosine wave
□ Differential outputs of A+/A- and B+/B- phase
Apllication
Motor control application (AC servo motor, robot, CNC spindle motor etc.)
Since the analog output voltages produced by SMRE show sine/cosine waves with little distortion corresponding to gear rotation , it is possible to transform the voltages to angle of gear rotation with high resolution over the 20bit by electrical interpolation. It is suitable for high accuracy motor control application and other.
