INDUCTIVE TORQUE SENSOR FOR ROTATING SHIFTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240247988 titled 'INDUCTIVE TORQUE SENSOR FOR ROTATING SHIFTS
The described techniques in this patent application focus on inductive torque sensors that incorporate independent target coil and pickup coil systems. By leveraging the principles of inductive angle sensors and the specific physical arrangement of target coils, this sensor can independently determine the rotational position of both the input and output shafts using separate pickup coil systems. Combiner circuitry is utilized to calculate the torsion angle by analyzing the signals induced in each pickup coil system. The sensor reduces or eliminates mutual coupling between the target coil systems by employing different k-fold symmetry periodicities in the target coils, enhancing robustness to external electromagnetic fields.

Original Abstract Submitted
the described techniques are directed to inductive torque sensors that implement independent target coil and pickup coil systems. by utilizing the various principles of inductive angle sensors, and as a result of the specific physical arrangement of target coils, the inductive torque sensor may independently obtain a rotational position (i.e., mechanical angle) of the rotatable input shaft via one pickup coil system, and a rotational position (i.e., mechanical angle) of the rotatable output shaft via another pickup coil system. combiner circuitry is also provided to calculate the torsion angle using the signals induced in each of two separate pickup coil systems. by using different k-fold symmetry periodicities in the target coils with respect to the coil configurations, the inductive torque sensor advantageously reduces or eliminates mutual coupling between the different target coil systems and provide robustness to stray or external electromagnetic fields.
