Turbo Compressors & Blowers

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. Given the elevated speeds, precise control becomes imperative to mitigate vibration and prevent motor overheating.

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

Tailored for the most challenging applications globally, KEB Variable Frequency Drives (VFDs) are particularly well-suited for high-speed turbo compressors and blowers. The KEB F5 drive offers configurable safety features, encoder interfaces, heatsinks, and communication ports, providing a comprehensive set of options to complement and enhance your high-speed motor applications.

KEB’s F5 drive incorporates an advanced control card, available in three performance tiers: Basic, Compact, and Application. It is offered in 230, 480, and 690 VAC classes, supporting up to 1,200 Hp. Additionally, the platform provides high-speed outputs, reaching up to 2000Hz, catering to the operation of high-frequency motors. This level of customization empowers machine builders to craft precise, tailored drive solutions that align with their specific application requirements.

Complementing the F5 drive, KEB Sine filters are accessible to enhance efficiency in turbo compressors and blowers by reducing rotor heating, limiting high-frequency transient emissions, and improving EMC load. This combination of control and automation solutions not only brings about notable efficiency gains but also ensures that high-speed motor applications operate more smoothly, functionally, and safely.
