The EVKT-KNOB is an evaluation kit for the MagAlpha magnetic position sensor family. The EVKT-KNOB allows users to run and test the MagAlpha sensor quickly. It is delivered assembled with a knob and magnet. The sensor is mounted in an end-of-shaft configuration.
The EVKT-KNOB is compatible with the MACOM kit, offering seamless connection and operation of the MagAlpha and allowing users to evaluate MagAlpha functionalities and performances, such as noise level, refresh rate, power-up time, magnetic field dependence, and so on
- Ready-to-Use Knob with End-of-Shaft Magnet
- Extra Spacers
- Compatible with MagAlpha Communication Interface Kit (EVKT-MACOM)
- IC Supported 1MA300
- IC Supported 2EVKT-MACOM
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).
