THE MAGNADRIVE ADVANTAGE
MagnaDrive is the world leader in magnetic power transfer. Our couplings and
Adjustable Speed Drives transfer torque across an air gap, eliminating the physical
connection between motor and load. Friction-free power transfer reduces harmful
vibration, increases misalignment tolerance, minimizes wear and tear on equipment,
and increases motor and equipment life, creating a lower total cost of ownership
than standard couplings and a lifetime of unwavering performance.
