Integrated magnetic end-of-shaft encoders for motors

Space-saving and maintenance-free solution for precise angle and position measurement in compact drive systems

Kübler's integrated magnetic end-of-shaft encoders measure the angle of rotation directly at the shaft end. The change in the magnetic field caused by the rotation of a diametrically magnetized cylindrical magnet is used to determine the position. This technology provides a space-saving, maintenance-free solution for compact motor drives that is easy to integrate.

Magnetic Sensors with Diametrical Magnets – How They Work

When the magnet rotates with the shaft, the magnetic field changes in the plane of the direction of rotation. Directly below or next to the magnet, the sensors record the magnetic field changes as X and Y components, which are converted into sine and cosine signals.
The exact rotational position (angle) is calculated from these signals with a resolution of several thousand steps per revolution. Optionally, an energy-harvesting chip can store the number of revolutions if the power supply is interrupted.
