W E S T C A RMILANOITALYMILANO - ITALYOPERATING PRINCIPLES AND FEATURES OFROTOFLUID COUPLINGSSheet10-137A ENDate05-2006DRIVING PARTEMOTRICE PARTDRIVEN PARTEPART CONDOTTAOILMOTOR LATO MOTORE SIDEOILThe ROTOFLUID fluid coupling is designed to provide your plant withoptimum reliability and durability. It is fitted between the motor (drive)and machine (driven component).The ROTOFLUID fluid coupling comprises basically two impellers, withradial blades, opposed to each other, one connected to the motor shaftand the other to the input shaft of the Driven Equipment or Machine.The ROTOFLUID fluid coupling acts like a centrifugal clutch, by drivingan impeller, the oil passing from the blades to the driven part, which actsas a driven impeller, transmits the power to the Equipment or Machine.The oil, which fills the fluid coupling, transfers the torque and alsolubricates moving parts.Fluid couplings are the easiest and cheapest way of creating a perfectlyFlexible Drive Train, because no mechanical parts are necessarybetween the motor and the Equipment or Machine being driven.Without mechanical parts, there is practically no wear.Losses in the fluid coupling become power drops according to thefollowing formula:nmS%=- nux100n mwhere:n m= motor speed in rpmn u= output speed from the fluid coupling in rpmThe elasticity of the fluid coupling solves problems of power peaks inconventional electric motors and the machines they drive.THE ADVANTAGES OF USING FLUID COUPLINGS- easy start-up with gradual acceleration of the driven component- automatic load speed adjustment on the basis of the synchronousspeed of two or more motors- the drive train is protected against overloads- rotational vibrations are dampened- the torque transmitted complies with pre-set values- direct on-line start electric motors can be used, without star-deltastarters or slip-ring motors with rheostatFITTING A ROTOFLUID FLUID COUPLING GIVES YOU THEFOLLOWING BENEFITS:- a large range of accessories- interchangeable accessories on the basic cell- the dimensions of the shaft-pulley system are perfectly suited tothe needs of the drive train- all fluid couplings that utilise a belt drives, from Size 40P up, arefitted with ball bearings under the pulley to guarantee abovestandardradial loads- all the fluid couplings used for Horizontal applications are fittedwith ROTOFLEXI Elastic Flexible coupling, which gives theadvantage of, the user, of being able to replace the Flexibleelement, by removing it radially from the coupling, without eitherdisturbing the Motor or the Driven Equipment or Machine2

The dotted line represents the energy lost bringing themotor and load up to operating speed.As can be seen, direct start-up has the following disadvantages:- the difference between start-up torque (Ca) and the load requirement (Cm) is very low; the maximum torque is between 80%-85% of theoperating speed.- the current absorbed during start-up may be up to 6 times the rated current, causing electrical overloads and higher costs, an increase inmotor temperature and fewer possible start-ups.To limit peak currents, a characteristic of direct start-ups, a system with reduced voltage for start-ups must be used, most commonly the Y / ∆system. In this way the current and peak torque are reduced by about 1/3 compared to direct starting.The disadvantages of this type of start-up include:- greater costs for wiring (2 3-pole cables per motor)- high currents when switching from Y to ∆- you cannot choose start-up features because current/torque parameters are pre-set and cannot be adjusted.- It cannot be used for applications where the start-up requires a high load or resistant torque.START-UP WITH ROTOFLUID FLUID COUPLINGWith a ROTOFLUID fluid coupling between the Motor and Driven Equipment or Machine the motor can start up directly and the starting torque(Ca) is used solely to accelerate the rotor and primary part of the connected coupler.Figure 2. shows the peak current of an electric motor directly connected to the load, with direct start-up, and start-up with a fluid coupling. Thedotted line shows the energy lost as heat during start-up without a fluid coupling.In the first case, the peak current is 6 times the rated current, and continues to be high until the operating speed is reached.With a ROTOFLUID fluid coupling, the peak current is high for only a few seconds (the energy required to accelerate the rotor) and drops toacceptable values throughout the process of reaching operating speed.CHARACTERISTIC CURVES FOR START-UP WITH FLUID COUPLINGFigure 3. shows a characteristic torque curve for an electric motor, the stall curve of the fluid coupling and the slip curve at operating speed.The fluid coupling allows the motor to reach 80-85% speed in a few seconds (shift from point A to point B) where it meets the stall curve of thefluid coupling (slip=100%), the point of maximum motor torque.Point C is the point of functioning of the fluid coupling after the motor has reached operating speed.3

(In this case consult WESTCAR S.R.L.)This type of assembly has the following important benefits:F) - Greater dissipation of heat, above all during start-up, recommended where start-ups are frequent or lengthy;G) - Control is easier and the regulation of the oil level in the coupling is simplified, since the external part can be rotated without moving theDriven Equipment or Machine;H) - IMPORTANT! Where the coupling is fitted with THERMAL TRIP PIN, it continues to function even when the Driven Equipment orMachine comes to rest and the motor is rotating.In the absence of special needs or requests, the coupling is supplied for the Standard configuration.Please advise WESTCAR S.R.L. if you require, the selected Fluid Coupling to be quoted for Reverse Assembly.12

The pulses are converted into a voltage proportional tothe pulses frequency. This voltage is compared with a variable reference voltage (SET POINT). The internal relay changes over when the inputspeed is faster or lower than the fixed (SET POINT). It is emploied to control the shaft revolution speed. In case of speed decrease, the devicegives a signal to the operator.OPERATIONAs the trasmitted torque is increased, this gives rise to an increased slip of the fluid coupling. Possible overload can be detected by measuringthe resulting speed reduction in the driven half coupling by means of overload “SCD”. This with change-over contact at the output may either emitan alarm signal or switch off the main motor. A delaying action (max 120 sec.) prevent the unnecessary triggering of the relay, when the motor isstarted. It only occurs once when the operating voltage is applied. False alarms are prevented arising from very short torque fluctuations, by theintroduction of a preset time lag (max. 30 sec.)SUPPLY50÷60 Hz - Tolerance: -10%÷+6% - 24Vac STANDARD (115Vac or 230 Vac on request)- How to order: SCD 24 Vac49
