WOOD DALE, IL — Danaher Motion introduces the Torque Feedback Device (TFD). The new TFD combines tactile and position or velocity feedback with a steering wheel interface in a compact, IP66 rated package. This allows electronic vehicle system (EVS), personal mobility and related mobile off-highway machine builders to develop robust vehicles and machines that deliver the performance and maintenance benefits of electric or steer-by-wire systems, with the tactile response of a hydraulic system.
The Torque Feedback Device is available in five standard configurations, with torque densities ranging from 2.5 Nm to 12 Nm. They are tested to provide long life of more than 10,000,000 revolutions at 120 rpm, and are engineered to operate in ambient temperatures from -35ºC to 60ºC. The TFD has a footprint as small as 3.25 in. (83 mm) x 4.00 in. (102 mm), and is available as a stand-alone component that can be integrated into nearly any electric or steer-by-wire system, or as part of a larger Danaher Motion vehicle system.
The Torque Feedback Device provides a variable torque output in proportion to a DC input for steering and other by-wire applications by applying state-of-the-art friction materials and a patent pending electromagnetic actuation system. The TFD also incorporates redundant sensors for failsafe shaft feedback and serviceability. A modular design enables the device to be easy adapted to specific application needs. All components and the finished assembly meet EU directive 2002/95/EC (RoHS), and are designed for use in EN 1175 and IEC 61508 compliant systems.
