MagnaDrive
MagnaDrive Corporation is a Redmond, Washington-based manufacturer of permanent magnet-based torque transfer products — magnetic couplings and adjustable speed drives — designed to replace the physical shaft connection between a motor and its load with a contactless air gap, using high-power neodymium-iron-boron permanent magnets to transmit torque without mechanical contact. Its product line includes Fixed Speed Couplings for constant-speed applications from 2 to 4,000 HP, the SYNCHRA™ series for synchronous no-contact magnet-to-magnet connection, the MAGZONE for ATEX-rated environments, and its Adjustable Speed Drive (ASD) platform — all targeting industrial applications in mining and cement, oil and gas, power generation, and construction where vibration elimination, overload protection, extended motor life, and energy efficiency are priorities. MagnaDrive also offers a Permanent Magnet Consulting Service for customers with custom process challenges, and its technology has been deployed at major installations including BP Cherry Point refinery and municipal water systems across the US and internationally.
