Adjustable Speed Drive

The MagnaDrive Adjustable Speed Drive (ASD) reduces your total cost of ownership with our revolutionary speed control technology. With decreased maintenance and operational costs, the MagnaDrive ASD improves process availability and system reliability. 

Available in a range of sizes and speeds, the MagnaDrive ASD is ideal for an array of industries and applications.


The MagnaDrive Synchra™ Series leverages a magnet-to-magnet synchronous connection to generate no-contact power for mission-critical applications. With ultimate torque and zero magnetic slip, the Synchra Series is ideal for oil and gas, industrial and wastewater applications. 

Our durable, compact, patented design uses the world’s strongest permanent magnets: neodymium-iron-boron magnets. 

Fixed Speed Couplings 

The MagnaDrive fixed-speed couplings line incorporates an air gap to isolate the motor from the road. Efficient and reliable, our couplings target constant speed applications for motors with 2 to 4,000 horsepower that reach speeds up to 3,600 RPM. 

Check out our three coupling families: Fixed Gap Coupling (FGC), MagnaGuard Delay (MGD) and MagnaGuard Torque Limiting (MGTL).


With a synchronous, magnet-to-magnet connection, MagZone from MagnaDrive™ powers vital equipment and boasts a tough, compact design. We use neodymium-iron-boron magnets — the strongest and most reliable magnets on the planet. The MagZone Series optimizes torque and eliminates magnetic slip, with no RPMs lost. 

The MagZone Series gives your mission-critical equipment a powerful, consistent connection. As a result, you get superior performance for applications in the oil and gas, industrial and wastewater industries.
