Space-saving and maintenance-free solution for precise angle and position measurement in compact drive systems
Integrated magnetic end-of-shaft encoders from Kübler measure the angle of rotation directly at the shaft end. The change in the magnetic field caused by the rotation of a diametrically opposed 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

Integrated encoder solutions with diametrical magnets – Design
- Diametral magnet - north and south poles are arranged on the side of the cylinder / the magnet is connected to the motor shaft
- Magnetic field sensors with signal evaluation - Energy harvesting technology for multiturn detection
- Shield plate for EMC protection against the motor brake
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.
