The best choice is solid rotor technology

It’s simple. Eliminate the gearbox and gain adjustable speed for all turbo applications. A solid rotor induction motor is a type of induction machine with a non-laminated rotor construction. The advantage of the stiff construction is unmatched stability and balance, which offers exceptional rotating system reliability for all types of turbo applications.

Solid rotor induction motors – up to 15,000 rpm

The Switch’s turbo induction motors replace a mechanical gearbox by an electrical one to give you full speed control for your system. By integrating an electrical motor with the load machinery, you get unmatched space and weight savings.
