Cooling options for high-speed solid rotor machines

Did you know you can choose from a variety of effective cooling systems for our high-speed solid rotor electrical machines? Solid rotor machines are a superb option for high-speed applications because they are robust, efficient and reliable. But because high-speed machines are characterized by high power density, even with the highest efficiency the loss density…

How will turbo fit into future energy solutions?

We just got back from the ASME Turbo Expo and Conference in Rotterdam where many were asking how turbo will fit into future energy solutions.

Everyone in the industry seems to be waiting, hesitating to move forward until it’s known which renewable or green gas will best address climate change – and how compressor and turbine applications will need to adapt to handle the new situation. Yet everyone must be ready to move once decisions are made.

Extending the power and speed capabilities of standard induction electric motors

Markus Silventoinen The Switch solid-rotor technology extends the speed capabilities of standard induction electric motors, filling the existing gap for applications running below multi-megawatt powers. Typically, standard 2-pole induction motors reach speeds of 3,000–3,600 rpm and with a variable frequency drive (VFD), can reach speeds up to 4,500 rpm. In high-speed applications, a high-speed gearbox…
