MagAlpha MA300 Angular Sensor for 3-Phase Brushless Motor Commutation and Position Control with Side-Shaft Positioning Capability DESCRIPTION FEATURES The MagAlpha MA300 magnetic sensor is an UVW Signals for Block Commutation all-in-one solution designed to replace Hall 11-Bit Resolution Absolute Angle Encoder switches for 3-phase block commutation in 500kHz Refresh Rate brushless DC motors and provide encoder data. Ultra-Low Latency: 3s The MA300 detects the absolute angular Serial Interface for Data Readout and position of a permanent magnet, typically a Settings diametrically magnetized cylinder attached to 10-Bit Incremental Output (A, B, Z) the rotor. The data acquisition and processing Built-In Linearization for Side-Shaft is extremely fast, allowing for accurate angle Mounting measurement at speeds from 0 to 100,000 7.7mA Supply Current RPM. Available in a QFN-16 (3mmx3mm) Since the measurement is spatially confined, Package users have flexibility in terms of magnet shapes APPLICATIONS and configurations. This helps relax mechanical tolerances and, in case the end-of-shaft Servo Drives position is not available, the MagAlpha MA300 Robotics operates away from the axis of rotation (side- Automotive shaft mounting). PSM/BLDC Motors Encoders All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
