Efficient Motion Control using Magnetic Position Sensing Technology

Dec 14 2022

Here we have a simple rotary to linear actuator solution. The ADMT4000 is positioned opposite a dipole magnet mounted on the end of the rotating shaft. You can see from the display that the sensor is relaying back the absolute multiturn information and from that the linear position information is inferred and also displayed. If we remove the power to the system at x turns and counting to rotate the shaft for an additional say x + 4 turns and then repower up the actuator, you will note that the ADMT4000 has tracked the mechanical motion with the power removed.

In this rotary to linear actuator example, you no longer need an absolute linear position sensor for position feedback control, this is provided by the ADMT4000 position at the end of the rotating actuator shaft. The ADMT4000 incorporates a precision angle sensor in combination with the Multiturn sensor which can be used for motor commutation in brushless motors.
