Absolute angle detection

Absolute angle detection

Rotation Angle Sensors

Issue #06...

You want to use an absolute encoder that determines the position even immediately after turning on the power.

Then what is our solution…

Absolute angle detection is possible with unique magnetic field vector Absolute angle detection is possible with unique magnetic field vector

The magnetic field vector created by the magnet depends on the rotational angle. Therefore, the absolute angle can be detected by sensing each magnetic field vector and calculating.

For example, AKM rotation angle sensor can detect the absolute angle even when the motor is stopped immediately after the power is turned on, eliminating the need for zero return operation.

The absolute encoder, whose structure is complicated by the optical encoder, can be realized with a simple structure of only "magnet and IC" by using AKM's rotation angle sensor.
