Stepless speed variations


“Variable Speed” means the change of the speed of a driven machine in running condition. The ELECON Variable Fill Scoop Fluid Coupling is therefore located between a constant speed motor and driven machine.

ELECON make ESC series of Variable Fill Scoop Fluid Coupling provides step less speed variations when connected to a constant speed electric motor. The variation in speed is obtained by change of quantity of oil in the main circuit through scoop tube movement, sliding in & out. The available speed regulation range depends on the type of load.

Mainly the ranges available are Centrifugal Loads 4:1, Constant Torque Loads 2:1, and Rising Torque Loads 1.5:1 etc., These ranges can be further extended provided operation is possible in the specified regulation range. (See Operating and Control Ranges in the catalogue).

By the use of ELECON – ESC coupling customer has benefit of energy saving /cost saving.

Increased service life of motor & driven machine.
