Angular Sensor for 3-Phase Brushless Motor Commutation with Side-Shaft Positioning Capability--Please See Position Sensor Design Support for All Supporting Software

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 (?ide-shaft?mounting) topologies are supported.

MagAlpha Communication Kit

The EVKT-MACOM is a communication kit for the MagAlpha magnetic position sensor family. The EVKT-MACOM offers a seamless connection and operation with MagAlpha test boards (TBMA) and evaluation kits (EVKT-KNOB). The kit contains a microcontroller motherboard, a collection of daughter boards adapted to different sensor boards and the related cables.
