Fluid Coupling
Fluid Coupling
Fluid Coupling effectively dampens the shocks and torque fluctuations. Also protects motor from sudden jamming of machines. A fusible plug allows the oil to escape out and isolates the motor in case of prolonged delay in clearing the obstruction.
- No wear of power transmitting elements.
- Motor always starts unloaded. So, it accelerates quickly to its optimum speed at which it delivers its peak torque.
- The torque multiplication at start-up enables a motor to be selected for running power of a machine, instead of its starting power required. Thus, acceleration of high inertia load is possible by a comparatively low powered motor. The rate of acceleration can also be controlled by varying the oil filling quantity. The shock free, smooth load take up is of great importance in some application.
- Maximum torque capacity of a coupling can be adjusted and limited to predetermined value to suit the motor or the machine, by adjusting the oil filling quantities.
- Simple, robust and more reliable, squirrel cage motor with simple star-delta starters combined with fluid couplings, can be employed for applications - which otherwise, require costly, special motors with even more complicated starting gears.
- Automatic load sharing and synchronization is achieved in case of multi-motor drives.
- Braking of a running machine can be effected by reversing the rotation of motor. The opposite torque developed by the reverse rotation of motor stops the machine.
