Think outside the gearbox with solid rotor technology
Our direct-drive, high-speed induction machines allow you to eliminate the mechanical gearbox, allowing you to reach higher speeds and unmatched energy efficiency.
Solid-rotor technology extends the speed capabilities of standard induction electric motors, answering the demand for high-speed motors when running below multi-megawatt powers.
0 rotor failures in over 10 years of industrial operation
Power range from 300kW – 2MW
Speeds up to 20,000 rpm
Our high-speed products are ideal for applications, such as blowers, compressors, pumps, vacuum systems and other industrial applications in the speed range of 6,000 – 20,000 rpm. Additionally, our customers have used these motors in various test-bench configurations. We are also willing to discuss projects involving multi-megawatt hermetically sealed and hydrogen compressors.

High-speed induction machines
Our standalone product range comes in two frame sizes – 315 and 400. The high-speed machines are designed to be coupled to driving or driven machinery through a separate coupling, for example a steel pack coupling.


Semi-integrated solutions
Semi-integrated machines include the compressor, turbine or pump impeller mounted directly on the shaft of the electric machine. The bearing system and rotor dynamics can be calculated and tailored to the application.
Semi-integrated solutions are available based on our successful long-term joint development projects with world leaders. Ask us more!
Fully integrated solutions
For ultimate system simplicity, we can offer integrated machines. Active parts of the solid-rotor machine can be completely tailored to suit different applications. We are happy to discuss the delivery scope case-by-case.

Disruptive environmental energy solutions
When you need to convert energy sustainably, store energy effectively or consume energy responsibly, our products provide an innovative approach. We are also involved in applications, such as permanent magnet (PMs) motors for mining and minerals and permanent magnet generators (PMGs) for hydropower plants.
Exergy, Japan
Exergy, a startup from the University of Tokyo, signed a contract with The Switch in January 2019 to develop a frequency converter to match their proprietary-technology-based proton battery, which is used for a next-generation storage system.
SustainX, USA
US-based SustainX, a pioneer in isothermal compressed air energy storage (ICAES) technology, disrupted the current energy storage industry with its transformational cost competitiveness.
New blower for Tier III compliance

MAN Energy Solutions has launched its EGR (Exhaust Gas Recirculation) electrical turbo blower for the marine market. The Electrical Turbo Blower (ETB) units will be installed aboard vessels as part of their main engines’ integrated EGR system.
Gateway, USA

In 2012, The Switch made a significant CHP converter delivery to the Gateway building in White Plains, New York. Commissioning was carried out in early 2013. The installation featured 3 converters in parallel and included an HMI. This was the second 2 MW+ installation for The Switch in the New York area.
Yonkers, USA

Following on the success of the Gateway project, The Switch delivered another CHP converter to the Yonkers Waste Water Treatment plant. This innovative installation utilizes gas from the digester to create electrical power. The converter allows the plants to accurately control power production and meet grid interconnect requirements.
MAN Energy Systems

MAN Energy Systems, formerly MAN Turbo, chose our solid rotor technology for a high-power compressor of 8 MW, 10,000–12,000 rpm, for a gas application that survives subsea installation with aggressive gases.
