High voltage traction solutions

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 high-voltage concepts enable rapid adaptation to various customer applications – from core electric motor components such as stators and rotors of the highest quality to complete, efficient traction machines, powerful inverters and complete electric axles for cars and commercial vehicles.

Auxiliary Equipment

Auxiliary motors and high-voltage relays complement our range of high-voltage applications for electric vehicles.

A growing number of small auxiliary motors are being used in the overall e-vehicle system, and their design in terms of efficiency, weight and size has an impact on the vehicle's performance.

High-voltage relays are sometimes responsible for crucial switch-on or switch-off processes where reliability is essential.

For both applications, SEG Automotive customers benefit from the company's many years of expertise in the field of e-machines.

E-Machines for Mild Hybrids

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 48V Electric Machine (EM). 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%.

Light Electric Mobility

System for high performance electric two-wheelers & three-wheelers: Our LEM Machines and Controllers are highly efficient which offers enhanced user experience with multiple drive modes that give enough stability on road.

The electrification of light vehicles like two-wheelers and three-wheelers is estimated to grow significantly over the next years. The main driver for this development is the benefit in terms of total cost of ownership the electric variant offers over the ICE (Internal Combustion Engine) counterparts.

SEG Automotive has developed LEM series of motors and controllers especially for light electric mobility. Thanks to the modular concept, compact packaging and high power to weight ratio, these chassis mount e-motors can be flexibly and easily integrated in the powertrain of two-wheelers and three-wheelers. This includes support for different drive configurations and customizable controllers for various drive modes, which offer flexibility and enhance user experience.

Our portfolio consists of e-axles, various HUB-Motor solutions, Mid-Motor solutions, controllers and additional components like batteries.
