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.”
