MA120中文资料Angular Sensor for 3-Phase Brushless Motor Commutation数据手册MPS规格书

描述 Description

The MagAlpha MA120 magnetic sensor is an all-in-one solution designed to replace Hall switches for 3-phase block commutation in brushless DC motors. The MA120 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder attached to the rotor. The data acquisition and processing is extremely fast, allowing for accurate angle measurement at speeds from 0 to 120,000 RPM.



The MA120 supports a wide magnetic field strength range, which helps relax mechanical tolerances and simplify system design.
