Non-contacting torque sensor for power steering
TT Electronics’ Sensing and Control division has expanded its series of sensors for electronic power steering (EPS) applications.
The device, designated the Magnetorque Plus, combines a non-contacting torque sensor with a multi-turn position sensor in a single package.
The torque and position sensing functions are based on Hall Effect technology with a non-contact design that maximises mechanical durability to support a minimum lifetime of 1 million shaft rotations without degradation of electrical outputs.
Dual torque outputs allow accurate diagnostic calculations and availability of custom output slopes.
Instant output at “power-on” provides several benefits, including enhanced accuracy and no standby current. The position output provides absolute multi-turn position information up to ±900° of rotation.
