Asahi Kasei Microdevices Corporation, (AKM), has released the MS0043 corresponding to the smallest gear wheel* compared to other AKM semiconductor magnetoresistive elements, (SMRE), expanding the lineup of AKM’s SMRE. The MS0043 achieves high resolution rotation angle detection exceeding 20-bit from electronic interpolation. This is due to its stunning temperature characteristics while having extremely small variability among individual devices. This is top-level performance among magnetoresistive elements. The MS0043 is assumed to be used in small AC servo motor applications, capable of composing a magnetic encoder with a small gear wheel and a bias magnet.
* According to AKM’s research on July 2018.
The MS0043 is designed to have the smallest system offset voltage when it is used with a gear that has m=0.4 and 32 to 64 gear teeth, (Φ13.6 to 26.4mm). Therefore, it contributes to minimizing AC servo motors.
m is standard value to express the size of gear wheel, m=(Pitch Circle Diameter)/(No. of Tooth).
Since phase A and B are output with phase differences, it is possible to eliminate in-phase noise by taking the difference and contributing to high precision and high resolution of the magnetic encoder because the output amplitude can be obtained twice.
