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
In the near future, Sensitivus will be able to deliver samples of the upgraded SG3Q sensor module. The cadence sensor is improved to obtain signals from an inductive system instead of magnets. Using inductive signaling reduces the costs and improves both accuracy and latency.
In addition, the sensor will include an angular sensor based on the same inductive, frictionless technique. This can improve applications involving shifting, help reduce erroneous torque input from pedals hitting curbs, etc. and increase 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 for 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.
