Sensors for series drives and test benches – functionally safe, high-speed capable, and stray-field resistant
Speedy C-sample development 
Customized manufacturing (CtO) 
Tried and tested quality Precise sensing is a critical factor for efficiency, performance, and safety in modern electric drives.
Accurate rotor position detection is the key control variable in synchronous motors, while precise speed measurement enables stable asynchronous control. At the same time, high rotational speeds in traction drives place demanding requirements on measurement accuracy and signal quality.
Additional challenges arise from harsh operating environments: power electronics generate EMI and stray magnetic field interference, while thermal and vibration stresses act on the sensing components. Space constraints within the motor further complicate integration, and functional safety requirements such as ISO 26262 and ASIL impose additional design demands.
We offer the right sensors – precisely tailored to your requirements. From small to large production volumes: our robust, durable, and reliable products are forward-looking solutions from a single source.
High-resolution rotor position encoders in drive control systems enhance motor performance and reliability while increasing energy efficiency.
High-precision sensors improve drive efficiency, reduce mechanical stress, and contribute to smooth, comfortable driving behavior.
Hybrid motors switch rapidly between electric and mechanical drive. Rotor position encoders enable precise synchronization of both drive modes.
Our bearingless rotary encoders and rotor position encoders deliver maximum measurement accuracy, highest reliability, and consistently stable signal quality even at extremely high rotational speeds.

ASIL stands for Automotive Safety Integrity Level. It describes the safety requirement levels according to ISO 26262 for electrical and electronic systems in road vehicles. The levels range from ASIL A to ASIL D, with ASIL D setting the highest requirements. The classification results from a hazard analysis and risk assessment of the respective vehicle function. Requirements for the components involved are derived from it, for example for a rotor position encoder. Which diagnostic functions and fault control measures are required depends on the safety concept of the entire drive.
Sensors provide important information for the control and monitoring of electric drives, for example on rotor position, speed, or temperature. Diagnostic functions can detect faulty measured values, signal interruptions, or internal faults. Plausibility checks and, depending on the safety concept, redundant measurement information additionally support fault detection. The drive control can then trigger a defined reaction in time, such as limiting the torque or safely shutting down the drive. What matters is the coordinated interaction of sensor, signal transmission, evaluation, and control. Sensors thus make an important contribution to the functional safety of the overall system.
