High-speed turbo motors use an advanced drive-train design
The Switch
This company’s permanent-magnet direct-drive, high-speed turbo technology train and converter packages are designed for many industrial, marine and wind applications, and are available with speeds up to 15,000 rpm. The solid rotor-induction motor uses non-laminated rotor construction. This solid-rotor technology allows the mechanical gearbox to be eliminated for improved speed control, and stiff construction improves stability and balance. By integrating an electrical motor with the load machinery, space and weight needs are reduced, and the unit scales easily to higher powers and speed ranges, says the company. — The Switch, Helsinki, Finland
