Gradually, as the necessity of drastically reducing, or altogether replacing, fossil fuels becomes evident, the necessarily increasing reliance on some sort of electrical power will lead to a fundamental change in available electric circuit capability, enabling boost to be created electrically.
With its near silent operation and extremely high efficiency (usually in the range of 97-98% mechanical torque transfer efficiency), the Rotrex traction drive supercharger lends itself ideally to be mated with a driving electric motor.
The compactness of the Rotrex traction drive matches the sizes for electric motors of equal power transfer capability and speed capability, thus making for a compact, attractive, integrated solution taking up the minimum physical space possible.
The inverter needed to drive and control the electric motor can either be integrated with the motor or can be separate, if such is desirable.
In any case the resulting combination provides fully variable boost, with virtually no delay in its adjustment, always ensuring the immediate desired air delivery at any point on the compressor flow map for as high an overall system efficiency as possible.
