Product Information

The MagAlpha MA100 magnetic sensor is an all-in-one solution designed to replace Hall switches for 3-phase block commutation in brushless DC motors. The MA100 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 100,000 RPM.

The MA100 supports a wide range of magnetic field strengths and spatial configurations, which help relax mechanical tolerances and simplify system design. Both end-of-shaft magnet and off-axis magnet positioning (“side-shaft” mounting) topologies are supported.
