The FluxDrive Technology

Flux Drive's Goal: To develop an engineering alternative to the electronic variable frequency drive (VFD) with comparable or better performance and fewer limitations.

Flux Drive's Solution: A patented mechanical Adjustable Speed Drive (ASD) that reduces or eliminates many of the issues currently plaguing VFD users.

The savings in engineering costs from this patented technology are significant:

Higher Engineering Efficiencies: There are no electrical windings and no electricity creating the magnetism, so no harmonics or power fluctuations interfere with operations.

Best Efficiency for the Motor: Flux Drive products allow the motor to run at its best efficiency point. They enable much higher motor operating efficiency levels than those allowed by VFDs.

Lower Cost of Installation: Flux Drive products have a protective coating to protect them in harsh environments, such as chemical vapors or the ocean environment (saltwater or salt air).

Savings on Maintenance: The ASD passes the torque through air via magnetic flux, not moving parts that touch, so no parts wear out due to normal operations. Most industrial suppliers will carry any parts that need replacing.

Retrofit to existing motors: Flux Drive products have been retrofitted to existing motors at Evergreen State College and the Seattle Aquarium. The Flux Drive Coupling and ASD incorporate a flex-plate on the hub, allowing the drive to work even if major shaft misalignment existed.

Safe, Reliable Operation in Harsh Environments: The protective coating on Flux Drive products insulates them from harsh environmental factors, such as chemical vapors or the ocean environment (saltwater or salt air).

Flux Drive's ASDs target AC motor applications rated from 15 to 100HP and 1700 to 3600 RPM. Example installations include controlling the speed of blowers, boilers, cooling towers or pumps.
