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

Inductive encoders operate using a high-frequency signal that is affected by the rotational movement of the rotor. The amplitude of this signal changes depending on the rotor's position. Receiving coils on the stator side continuously detect these changes across the entire circumference.
