Advantage:No wear of power transmitting elements. Motor always starts unloaded. So, it accelerates quickly toits 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 the 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.
Range of Power Transmission :-0.75 kW to 3100 kW
Efficiency :- 0.96%
