MagnaDrive MGTL couplings are the best torque limiting shaft coupling option in the market. The MGTL offers all of the same features of the MGD and in addition the MGTL has a complete disconnect feature. Complete disconnection occurs when high torque repelling magnetic force occurs due to additional slip. This force completely uncouples the motor from the load and allows the motor to run uncoupled. This is a great option where load seizures can occur. The coupling will disconnect and save your equipment. It resets itself once the motor is turned off.
Fluid drive couplings can also offer a smooth start like the MGD or MGTL but they are plauged by many other problems. Fluid Drive couplings require oil which can spill out and this is a haz-mat issue. Flexible shaft couplings cannot provide a smooth start but they do allow for some flexibilty. However, if your application is critcal and truley needs a "flexible coupling" then MagnaDrive magnetic couplings are the best solution. If you have an application that experiences frequent load seizures than fluid couplings or flexible couplings cannot help. In this case, MagnaDrive MGTL will completely decouple itself saving your equipment.
Q: How does MangaDrive MGTL compare to fluid drive couplings?
Both type of couplings can be used for a smooth start, but only the MangaDrive MGTL has a complete disconnect feature built in that will save your equipment in the case of a load seizure. A fluid drive coupling would just break and spill oil everywhere and cause damage to the motor shaft and the load shaft. Also it is important to note that MangaDrive magnetic couplings are easy to understand and work on, fluid couplings are complicated and have a lot of parts that could cause the coupling to fail.
Q: How does the MangaDrive MGTL de-couple itself?
If a load seizure occurs the repelling force pushes the magnet rotor so far away from the copper rotor that there is no torque being transferred. The motor will continue to spin the copper rotor at full speed but since the gap between the magnet rotor and copper rotor are so great no torque is being transferred through the coupling.
Q: After I clear my jam what do I have to do to the coupling?
A: Nothing! That is the great thing about the MGTL coupling. In the case of a load seizure there are a few very simples steps to complete to get you back up and running. First, stop the motor for safety reasons. Second, un-jam your load. Third, restart your motor. The coupling resets itself and needs no input at all.
