Similarly, there are the supports D and E composed of two hydrostatic pockets each, 17, 20, 18 and 19, representing the wedges (keys) of the main guide way F.
The contact surface between the two parts (live surface) is made by ink-spotting the pocket and removing a layer of material.

Abstract.
Therefore it is very challenging to find out how to reduce the energy loss and heat generation in a conventional hydraulic system and what is the key for energy saving if a common pump is used to supply flow rate to the circuit, this is primarily due to using a controller for electro-hydraulic system is developed to improve the energy saving performance of the hydraulic system considerations.
The torque developed by the induction motor follows the equation below (6) Despising the voltage drop caused by the stator impedance, the magnetizing flux is found to be (7) where T is torque available on the shaft (N.m), fm is magnetizing flux (Wb), I2 is rotor current (A) depends on load, V1 is stator voltage (V), and k1&k2 are constants depend on material and on the machine design.
