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.

The sensor system will lower power consumption in all applications. The compact design can be completely sealed, potted, or coated according to your needs.

This sensor technology was superseded by the SG3Q technology to remove the need for magnets and provide a much faster response.

SG3Q – Gen 2: inductive torque, cadence, and angle sensors

Sensitivus delivers 100% customized prototypes of the upgraded SG3Q sensor module. The sensor includes an inductive absolute angle sensor, reducing both assembly costs, accuracy, and latency.

The angle sensing improves cadence calculation and allows response within one degree of rotation. This can also improve applications involving shifting, help reduce erroneous torque input from pedals hitting curbs, etc. It can also be used to increase responsiveness by making torque measurements relative to the typical max torque for the given 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 enable better performance, smaller size, lower cost, and better reliability. Like the SG2Q and SG3Q, this robust and low-cost device 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.
