Eddy Current Clutch Control - Emerson Control Techniques Focus 3N User Manual

Focus 3 Non-Regenerative Drives have been used to replace many of our old Eddy
Current Clutch Drive units. To regulate speed the clutch output shaft typically employed
a tachometer (typically AC but DC could also be used)
for 1235 / 367 Eddy Current Controllers
The Eddy Current controls were a very popular means of providing variable speed
control of a machine back in the 1970's. A simple 10-amp eddy current controller could
actually control the speed/torque of a 900 HP motor. The F3N2C-EC can provide coil
current up to 10 amps dc in 5 ranges starting at 2.7amps by setting a programming
jumper. This current level can be "fine tuned" to the exact coil current of the clutch being
controlled. For more specific information, refer to CTAN213 via the Internet at our
