Angular Sensor for 3-Phase Brushless Motor Commutation with Side-Shaft Positioning Capability--Please See Position Sensor Design Support for All Supporting Software
Learn about our Evaluation Kit
Product Description
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.

Long Eval Board for MA100
The TBMA100-Q-LT-00A is the long test board for the MagAlpha magnetic position sensor MA100. The sensor is mounted on the edge of the board and can therefore be used in both side-shaft and end-of-shaft configurations.
It requires the communications kit (EVKT-MACOM) and the Macom App Software (see below) to evaluate MagAlpha functionality and performance with your set-up, such as noise level, refresh rate, power-up time, and magnetic field dependence.
In addition to this long test board, there is a round format version (RD) where the sensor is mounted in the center of the board for end-of-shaft configurations

Round Eval Board for MA100
The TBMA100-Q-RD-00A is the round test board for the MagAlpha magnetic position sensor MA100. This configuration is used for end shaft sensing.
It requires the communications kit (EVKT-MACOM) and the Macom App Software (see below) to evaluate MagAlpha functionality and performance with your set-up, such as noise level, refresh rate, power-up time, and magnetic field dependence.
In addition to this round test board there is a long format version (LT) where the sensor is mounted on the edge of the board and can therefore be used in both side-shaft and end-of-shaft configurations.
