Torque sensing is key as Lotus hybrid blooms

Torque sensing is key as Lotus hybrid blooms
The torque-current characteristics of a combined motor-generator developed for a Lotus-based hybrid car have been comprehensively mapped by a TorqSense digital torque sensor. Specialist electromagnetic design company Elektro Magnetix (EMX) of Brighton developed and tested the motor-generator for Lotus Engineering's EVE (Efficient, Viable, Environmental) Hybrid.  This is a technology demonstrator that is showcasing many of the medium term solutions that will be used to reduce vehicle emissions.
 
Jonathan Bremner of EMX explains that the mapping was essential, but could not be done in-house. "We are a design house, so tend to sub-contact testing to other organisations. With this project we needed to plot out the full range of performance, but had only a tight time window to do all the work."
 
So EMX worked with a testhouse to design a simple yet effective test rig. It was not long before the specialist engineers had settled on using a TorqSense torque sensor from Sensor Technology as they could design a rig around it very easily, and then it was very quick and simple to use.
 
Unlike other torque sensors TorqSense is mechanically simple with its sensors fixed to the shaft and a rotating RF antenna used to allow non-contact coupling with its digital electronics offering immunity from magnetic fields, so there is no need for complicated and delicate slip rings or large transformer assemblies to obtain signals.
