High-speed solid rotor motor and drive packages for gearless applications

Yaskawa Environmental Energy / The Switch advances the industrial world with high-speed solid rotor motors and variable speed drives for better system efficiency – up to 20,000 rpm. Applications that can benefit include blowers, compressors, pumps, vacuum systems and other high-speed industrial applications.

More compact with superior durability

The solid rotor construction provides high mechanical strength and stability, so higher motor efficiencies can be reached. The structure is also more compact and lighter in weight, requiring up to 50% less space than a conventional design.

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.

Gardner Denver Pulp & Paper

Gardner Denver Pulp & Paper, formerly Runtech of Finland, has placed continuous volume orders for high-speed motors and drives to be used in its paper machine vacuum systems that run at over 10,000 rpm.

Full reference case

FIMA, Germany

German FIMA Maschinenbau GmbH, our first chemical industry reference, ordered a series of 200 kW high-speed motors for turbo blowers with a speed of nearly 11,000 rpm.
