Inductive torque, cadence, and angle sensors of the future
SG2Q – Gen 1: torque and cadence sensors
The contactless sensor module integrates a strain gauge/RFID-like torque sensor and a magnet-based cadence sensor allowing an air gap between the rotor and the stator up to several mm.
The compact SG2Q technology allows high accuracy, low latency, and very flexible integration for both mid-drive, direct/geared hub motors, and other applications.
SG3Q – Gen 2: inductive torque, cadence, and angle sensors
Sensitivus will deliver customized prototypes of the upgraded SG3Q sensor module. To improve the cadence sensor, it obtains signals from an inductive system instead of magnets. Using inductive signaling reduces costs and improves both accuracy and latency.
In addition, the sensor includes an angular sensor based on the same inductive, frictionless technique. This improves applications involving shifting, helps reduce erroneous torque input from pedals hitting curbs, etc. It also increases responsiveness by making torque measurements relative to the typical max torque for the crank angle.
SG4Q – Gen 3: smaller and even lower cost
The next step is to incorporate the torque, cadence, and angle sensor system into a custom chip. This will secure better integration, smaller size, and lower cost. Like the SG2Q and SG3Q, this robust and low-cost module can be customized to fit any mechanical design of pedelecs and small electric vehicles.
Sensitivus is constantly working on upgrading our sensor design. If you have any questions concerning future torque, cadence, and angle sensors, and whether they fit into your design, please contact our technical team in the contact form below.
