The MagnaDrive Coupling line has three product families: Standard (FGC), MagnaGuard Delay (MGD) and MagnaGuard Torque Limiting (MGTL). In order to identify generally which size MGD or MGTL is right for your application please review the table below. For FGC Couplings, call MagnaDrive Sales & Applications Engineering.

MagnaDrive Coupling Selection

To select a Coupling for your system, determine the maximum running horsepower and maximum running speed required by your application. Both the speed and horsepower information is important, since the MagnaDrive Coupling must be sized to deliver the maximum torque needed to start and operate your system. The MagnaDrive Coupling requires some slip between the driven speed and the output speed. The Couplings sized in this table have 1% to 3% slip when operated at full rated motor speed and torque. This information is for general sizing only. Contact MagnaDrive Sales & Applications Engineering for detailed information on your particular installation.

Installation and Dimensional Information

The Coupling consists of two major components. The Copper Conductor Assembly is directly connected to the motor (input) shaft. Its weight is shown in the “Weight” column of the “Conductor Side Assembly” in the table above. The Magnet Rotor Assembly is directly connected to the load (output) shaft, and its weight is shown in the “Weight” column of the “Magnet Side Assembly” in the table above. The overall dimensions required by the MagnaDrive Coupling are defined in the cross-section drawing and the table. The axial distance needed between the end of the motor shaft and the end of the load shaft to install these two assemblies is stated in the “DBSE” column of the table. The actual diameters of your motor and load shafts will be used to size the mounting hub dimensions prior to the installation of the Coupling. The peak torque capacity is independent of speed, and is stated in the table.

MagnaDrive Motor Base and Installation Hardware

Adjustable motor mounting plates are available to facilitate installation. These items have been engineered to simplify the conversion and installation of the MagnaDrive system at the site. Contact us for details on these items.
