[MS0043] 018006870-E-00 - 1 - 2018/06 Semiconductor Magnetoresistive Element Composition MS0043 generates differential A+/A-,B+/B- phase analog output voltages by combining module m=0.4 gear and bias magnet. Application Motor control application such as AC servo motor, robot and 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 small and high accuracy motor control application and other. Feature Design optimized for 32 to 64 teeth small gears with m=0.4. 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 Gear Configuration Equivalent Circuit p = m×π(m : module） Semiconductor Magnetoresistive Element MS0043
