Characteristics
The hydrodynamic coupling is a device of transmission of primary importance
and has a large field of application. It is simultaneously a gradual starter
and a stress eliminator and it is able to create in every moment and automatically
and equilibrium between the motor and transmission of the operating machine:
therefore it eliminates every dangerous and unexpected overload and protects
the motor and the transmissions as well.
Advantages
The Hydrodynamic coupling, inserted into a transmission for starting up a high
inertia machine controlled by ab asynchronous electric motor with Direct on
Line Startin, has the following advantages:
- Eliminate the rigidity of the mechanical transmissions and guarantess the
flexibility of a Hydraulic transmission, withstanding all the shocks, torsional
vibrations and unexpected overloads, and protect the motor and driving machine.
- Reduces peak current during start-up. The electric motor rapidly reaches
the operating speeds with low peak current.
- Permits smaller motor sizes according to the power demand of the driven
machine.
- Permits a high stop start duty cycle even under load, sudden changes of
direction and plug(reverse) braking.
- Distributes the load installations where two or more motors are installed.
The Hydrodynamic coupling allows every motor to reach its own operation speed,
automatically distributing load demand.
