High voltage E-Machines.

Our efficient high voltage automotive e-machines are based on more than 100 years of experience in developing and producing rotating machines.

At SEG Automotive, we commit ourselves to an electrified future of mobility. Given today's challenges of the greenhouse effect and air pollution, electrification of the powertrain is essential for the automotive industry.

We are a driver of this transformation thanks to our many years of experience in the production of e-machines.

Our scalable e-motor concepts enable rapid adaptation of high-voltage e-machines to various customer applications – from light-weight motors for auxiliary units such as air-conditioning compressors to high-powered engines and components for passenger cars and commercial vehicles.

48V E-Machines.

Plug&play solution for higher efficiency: Our 48V E-machines save up to 25% CO2 by hybridizing conventional powertrains and can enable full electrification of light vehicles.

Our Boost Recuperation Machine (BRM) transforms any conventional internal combustion engine into an efficient mild hybrid with minimal effort: by replacing the 12V generator with the 48V BRM, fuel consumption and CO2 emissions are reduced significantly.

The EU has officially recognized the BRM as an eco-innovation, which enables manufacturers to receive additional CO2 credit and further reduce their fleet consumption.

Simply ‘swapping’ in the BRM on the belt drive (P0) already brings up to 15% CO2 savings. These can be boosted even further with our Electric Machine (EM) 48V Platform. It can be flexibly integrated into any powertrain, for example on or in the transmission as well as on the rear axle, and power additional driving features and a reduction in CO2 emissions of up to 25%.

We also offer a dedicated series of 48V e-machines for two- and three-wheeled light vehicles, which enable them to drive completely emission-free and significantly reduce urban pollution.
