Carrying the load with MagnaDrive Couplings

MagnaDrive has developed both an Adjustable Speed Drive and a shaft coupling that employ powerful rare-earth permanent magnets to transmit torque across an air gap with no physical connection between the motor and driven equipment.

The ASD is designed for variable-speed applications such as pumps, fans and blowers.

The magnetic coupling is intended for constant speed applications.

MagnaDrive Couplings provides several advantages over conventional fluid couplings including low cost, easy installation, efficient torque transfer without vibration, overload torque protection, cushioned start and stop, misalignment tolerance and low maintenance.

A unique benefit of the MagnaDrive coupling is its performance in torque overload situations such as material jams or excess weight. The coupling automatically disengages, shutting down the system and preventing damage or destruction of the motor and driven equipment. When the jam is cleared, the coupling automatically resets to resume operation.

The MagnaDrive MGD industrial coupling is targeted at constant speed applications on 2 to 2,000 horsepower motors with speeds up to 4,500 RPM. MagnaDrive Couplings incorporate an air gap to isolate the motor from the load. This eliminates vibration transfer, equipment damage and downtime, and the need for costly and time-consuming laser alignment. Further, MagnaDrive Couplings are virtually maintenance free.
