Electric Variable Transmission

The Electric Variable Transmission (EVT) is an innovative transmission concept consisting of two concentric electrical machines. This means there are only two moving parts. It has two mechanical ports and one electrical port.

The EVT is a fully scalable system with a range from light duty to very heavy duty applications. Moreover, it can function as a fully variable transmission with the possibility to be hybridized when using the electrical port. 

This Electric Variable Transmission is a product of the Electric Variable Transmission BV. It is a joint venture between the high tech companies Altramotive, EMechForce and Magnetic Innovations. A close collaboration with research organization TNO has also been formed. Visit www.electricvariabletransmission.com for more information.

Key features

The customer’s benefits of the system are:

    • Reduced fuel consumption due to engine operation near the optimal efficiency points, engine idle stop, engine downsizing, regenerative braking and higher alternator efficiency.
    • Emission reduction due to enhanced start stop, avoiding fast engine transients, electrical after treatment, pure electric mode.
    • Improved drive ability and comfort due to continuously variable transmission and transient boost.
    • Higher performance due to electrical boost and optimum power use of the engine.
    • Individuality due to unique patented technology. This means that transmission suppliers and OEMs can offer added value to the end user.
