Yaskawa Environmental Energy / The Switch has delivered thousands of turbo motors in serial production to several world leaders for their specialized high-speed pump and compressors applications. Based on more than two decades of experience, the same technology is now introducing motors paired with drives, offering unrivaled cost and size advantages in powers of 100 to 600 kW and speeds of 6,000 to 21,000 rpm.
The age of the gearbox is slowly starting to fade, and a new standard is on the rise. For the first time, the superior technology presently available only for large-volume customers is now being offered as standardized packages, making the numerous advantages easily affordable for a wider range of high-speed applications.
The robust solid rotor motor eliminates the need for a gearbox, while allowing the application to reach higher speeds and availability. Mechanical problems associated with gearboxes are no longer an issue. Fewer components also reduce the need for extra parts and maintenance.
Machine builders can enjoy high motor efficiency due to the advanced rotor structure. The solid rotor construction provides high mechanical strength and stability. It is also more compact and lighter in weight, requiring up to 50% less space than a conventional design.
Each solid rotor motor is paired with a matching YASKAWA GA700 drive to create a perfect package for ease of use. The application can take advantage of full speed control over the entire range, ensuring efficiency and energy savings of the system.
Fast payback time
According to Mikko Lönnberg, Business Unit Manager for Turbo / Industry at Yaskawa Environmental Energy / The Switch, companies have been able to realize a return on their investment in as little as two years.
“We see this as a unique opportunity for all types of applications that can benefit from our experience with high-speed motors, such as fans and turbo blowers, vacuum systems, turbo generators, compressors for industrial air gas and chillers as well as turbo pumps. Now, they can tap into our decades-long expertise and get an easily affordable solution to help them set new standards in their selected business area,” Lönnberg continues.
“We’re also happy to work with customers to customize a solution if their specifications so require,” he adds. “Since we have been successful with long-term joint development projects in the past, we’re always pleased to continue.”
Motor series specifications
The solid rotor motor is available from 100 kW to 600 kW of power and rotating speeds from 6,000 rpm to 21,000 rpm. Operating voltages range from 380 V to 690 V. The air- or liquid-cooled motor comes in three different frame sizes: 250, 315 and 355.
