With nine shaft diameter options per encoder, the AMT31 and AMT33 Series can easily mount to almost any brushless motor. Their low mass disc means virtually no additional backlash or increased moment of inertia making it a more reliable component for measuring and controlling the motor. Their compact packages also allow for mounting in tight spaces and to small motors. Zero position is easily set by Same Sky's AMT Viewpoint GUI or by the AMT One Touch Zero Module accessory. Installing a commutation optical encoder onto a brushless DC motor can be an iterative and time-consuming process. The optical disk must be physically and precisely rotated to align with the correct motor windings. Once aligned, the assembly must then be checked via back EMF to ensure mounting accuracy. This process can take upwards of 15 minutes per motor. The AMT, being ASIC and MCU based, reduces this time-consuming process to a few seconds via the “One Touch Zero” feature, saving time and cost during the manufacturing process.
