Due to its no contact design, Magnetic Drives( Gear/Coupling ) are not designed to run at extensive RPM rates. The RPM rate will vary depending on size and configuration, but sizes 22 and up were able to run without any issues at 1500RPM without any load. Please, remember that due to its fairly low torque rate, it is crucial that the system’s motion profile is not erratic and acceleration and deceleration stay at low values.
