MAHLE Powertrain helps launch new 20KW Aeristech Compressor

MAHLE Powertrain has helped to launch an innovative new 20kW electric motor at the opening of a new Warwick, UK headquarters for Aeristech, the developer of power dense and efficient high-speed electric motors.

As an early adopter of Aeristech technology, MAHLE was invited to take part in the launch of the company's most powerful compressor, which provides greater torque density than any same-rated rival technology, reduced size for enhanced modularity and a significant increase in continuous power rating.

The applications for Aeristech's new 20kW motor include traditional internal combustion and fuel cell passenger and commercial vehicles with stacks of up to and over 100kW, industrial, aerospace and marine. The company's existing technology has been utilised by MAHLE for use within the powertrain of its advanced downsizing demonstrator vehicle.

The Volkswagen Golf features 48V architecture and a 1.2-litre, 3-cylinder gasoline engine producing 193kW. This is achieved through the use of an Aeristech eSupercharger, which provides increased airflow alongside a traditional, larger turbocharger. 315Nm torque is produced from only 1500rpm, matching the performance of the original 2-litre turbocharged gasoline engine while offering a 25% reduction in emissions.

“Investment in our new, improved headquarters is a demonstration of Aeristech's commitment to developing and expanding our range of emissions-reducing technologies for the internal combustion engine,” said Richard Wall, Aeristech CEO. “We are hugely grateful to MAHLE Powertrain for the support it has provided both in showcasing our technology and helping with this exciting launch of our next generation 20kW motor.”

The 20kW motor is the latest additional to Aeristech's range of permanent magnet variable speed electric units, which are able to accelerate to rotational speeds of over 160,000 rpm in under a second. The technology has been a vital enabler for its range of air compressors, which provide both performance and economy benefits, high power density, low noise and vibrations, and compact and lightweight structure. The 20kW motor provides maximum mass flow of 150gs-1 and a peak pressure ratio of 3.2 at 130gs-1.

“We are delighted to assist Aeristech with the opening of its new facility and unveiling of its latest 20kW electric motor; as long-standing technology partners we have first-hand experience of the benefits its eSupercharger technology can bring and we look forward to working on exciting future projects together,” stated Simon Reader, MAHLE Director of Engineering Services. “Aeristech's eSupercharger is a key enabler for the extraordinary results achieved by our advanced downsizing demonstrator vehicle and we are sure that the new 20kW motor will help future projects to once again achieve or surpass expectations.”
