High-speed electrical motors and drives for gearless applications

Yaskawa Environmental Energy / The Switch advances the industrial world with high-speed electrical motors and variable speed drives for better system efficiency – up to 15,000 rpm with power ranging from 300 kW–1.5 MW. Applications that can benefit include blowers, compressors, pumps, vacuum systems and other high-speed industrial applications.

Think outside the gearbox

The Switch direct-drive, high-speed electrical motors allow you to eliminate the mechanical gearbox. Our robust solid rotor motor gets rid of the gearbox, while allowing the application to reach higher speeds and unmatched energy efficiency.


The structure is more compact and lighter in weight, requiring up to 50% less space than a conventional design. The solid rotor construction provides high mechanical integrity and rigidity. Without the gearbox, you can reach higher system efficiencies.

Our high-speed drive system consists of solid rotor motors together with the latest Yaskawa variable frequency drive technology. Together with the frequency converter, you get full control and variable speed over the entire operating range.
