Product Information

Back to top
The MagAlpha MA300 magnetic sensor is an all-in-one solution designed to replace Hall switches for 3-phase block commutation in brushless DC motors and provide encoder data. The MA300 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.

Since the measurement is spatially confined, users have flexibility in terms of magnet shapes and configurations. This helps relax mechanical tolerances and, in case the end-of-shaft position is not available, the MagAlpha MA300 operates away from the axis of rotation (“side-shaft” mounting).
