A rotating hydrostatic transmission comprising: a hydrostatic transmission in a shaft or a rotor, an outside the shaft or rotor situated master controller or processor configured to control and regulate a from the outside incoming adjustable power, wherein the master controller or processor controls or regulates the split of the power to two ends (2, 6) of the shaft or rotor, wherein the split is regulated by the angle of swash plates (7, 8) which adjust the variable displacement in axial piston pumps or motors (3, 5) with adjustable displacement, wherein the control or regulation is done by transferring a signal of desired or wished position or angle of the swash plates into the shaft or rotor, wherein the transfer of the signal is done by two separate pulse width modulated DC fed pulse trains, wherein a different width of the pulse is utilized as different signals of the value of the angle, wherein the value of the signal is compared in some slave controller or CMOS logics with an actual position or angle of the swash plates, wherein when there is a difference between the value of the signal and the actual position or angle of the swash plates, the difference is adjusted by a servo which gets its command from the slave controller, wherein the master controller or processor can also switch on and off auxiliary equipment in the shaft or rotor, like valves and charge pumps, wherein the controlling or regulating is done inside the shaft or rotor by two slave controllers and servo functions, wherein a transfer of power necessary for the logic and the on and off switching function of auxiliary equipment in the shaft or rotor is also done by the two separated DC energized pulse trains which also are voltage regulated, wherein the energized pulse trains are coming in one from each end of the shaft or rotor contactless by induction from a fixed attached coil over to coil at the end of the shaft/rotor, wherein the rotating hydrostatic transmission further comprises at least one relief valve (17, 18); a plurality of check valves (19, 20); and one or more tanks or accumulators, to take care of internal oil leakage in a pressure side of the rotating hydrostatic transmission. a hydrostatic transmission in a shaft or a rotor, an outside the shaft or rotor situated master controller or processor configured to control and regulate a from the outside incoming adjustable power, wherein the master controller or processor controls or regulates the split of the power to two ends (2, 6) of the shaft or rotor, wherein the split is regulated by the angle of swash plates (7, 8) which adjust the variable displacement in axial piston pumps or motors (3, 5) with adjustable displacement, wherein the control or regulation is done by transferring a signal of desired or wished position or angle of the swash plates into the shaft or rotor, wherein the transfer of the signal is done by two separate pulse width modulated DC fed pulse trains, wherein a different width of the pulse is utilized as different signals of the value of the angle, wherein the value of the signal is compared in some slave controller or CMOS logics with an actual position or angle of the swash plates, wherein when there is a difference between the value of the signal and the actual position or angle of the swash plates, the difference is adjusted by a servo which gets its command from the slave controller, wherein the master controller or processor can also switch on and off auxiliary equipment in the shaft or rotor, like valves and charge pumps, wherein the controlling or regulating is done inside the shaft or rotor by two slave controllers and servo functions, wherein a transfer of power necessary for the logic and the on and off switching function of auxiliary equipment in the shaft or rotor is also done by the two separated DC energized pulse trains which also are voltage regulated, wherein the energized pulse trains are coming in one from each end of the shaft or rotor contactless by induction from a fixed attached coil over to coil at the end of the shaft/rotor, wherein the rotating hydrostatic transmission further comprises at least one relief valve (17, 18); a plurality of check valves (19, 20); and one or more tanks or accumulators, to take care of internal oil leakage in a pressure side of the rotating hydrostatic transmission.
