KEB has earned a reputation for controlling high-speed motors used on turbo blowers and power generating systems. High speed motors can operate in excess of 100,000 rpm and typically use airfoil or magnetic bearings. At these speeds, precise control is required in order to reduce vibration and motor heating.

COMBIVERT F5 Drive
High speed applications are very demanding applications for VFDs. They require extremely stable motor control algorithms with very fast control loops. KEB’s VFD portfolio including the F5 drive meets all the requirements for high speed blower, compressor, and chiller applications. An important differentiator in this application is also KEB’s large installed base and application experience.
Efficient Solutions for Turbo Compressors & Blowers
KEB VFDs are purpose-built to handle the most difficult applications worldwide, making them uniquely suited for high-speed turbo compressors and blowers. The F5 COMBIVERT drive provides configurable safety options, encoder interfaces, heatsinks, and communication ports to complement and enhance your high-speed motor applications.
The F5 platform includes a state-of-the-art control card in three performance levels: Basic, Compact, and Application. It’s also available in 230, 480, and 690 VAC classes up to 1,200 Hp—and offers high-speed outputs (up to 2000Hz) for running high-frequency motors. This level of customization empowers machine builders to design precise, tailored drive solutions for their specific application needs.
In conjunction with the F5 platform, KEB Sine filters are available to reduce rotor heating further, limit high-frequency transient emissions, and improve EMC load in turbo compressors and blowers. Together, these control and automation solutions bring marked efficiency gains while making high-speed motor applications smoother, more functional, and safe.
