  The electrical power to drive the systems on the EDX eSeed precision air seeder is supplied
  via the high voltage system (“High Voltage”) of the tractor. Via TIM (Tractor Implement
  Management) the control electronics on the tractor are accessed. The implement controls
  itself through its own intelligence and makes use of the two most current and modern technologies
  in the range of ISOBUS for further improvement and efficiency of the machine.

  In contrast to the normal EDX, the drive systems for the blower fan and metering on the EDX eSeed have been replaced by high voltage motors (400 V) and are accessed via the power inverters on the tractor. The metering drive systems have been replaced by efficient servo-motors with clearly improved dynamics.
  On large pneumatic seed drills, the blower fans are hydraulically driven, an arrangement which offers a high degree of flexibility but, due to poor efficiency results in high fuel consumption. More and more comfort functions mean
  that the electric 12 V systems on usual tractors meet their limits.
  Hydraulics of the new system are only needed for the actuation of hydraulic rams, for example when folding. An additional advantage of the system is the independence from the engine speed of the tractor so that it is possible to operate the tractor at its optimum fuel consumption.

  Electric drive systems
  Electric drive systems - that drive system, of dynamic illumination to draw, high precision in the spatial ripple optimum speed control and homogeneity and high quality.
  This system, take-off and moment, speed and и adopted with required accuracy and of recent.
  Electric drive systems made of a motor, the reference position and enterprise content management , that have 3 parameter is enabled only for control : position, speed , current.
  The appointment Electric drive systems - controls its speed, , of the torque and for machine parts components mechanisms .
  As displacement, angle and fast control of moment and speed effected by feedback or closed loop techniques with automatic setting function for real time, to prevent disappearances excellent dynamic performance.

  Electric drive systems
  Thanks to the electric drives?
  the efficiency of the total system is clearly
  improved. On hydrostatic drive systems a mechanical efficiency of 60 % is anticipated.
  With an electrical system today, more than
  85 % is achieved. 20 kW, consumed as mechanical power, requires approximately 33.3 kW drive capacity in a hydraulic system, whereas in an electric drive line only approximately 23.5 kW are necessary. Here alone, fuel savings of up to 50 l of diesel per day are possible.

  TIM- implementing Tractor-Implement-Management
  Additional savings (of approx. 10 %) are realised
  because the seeder sends its demands for
  each individual operating parameter to the
  tractor. The implement controls the tractor
  and connects with it to become a modular selfpropelled
  vehicle – thus implementing Tractor-
  Implement-Management (TIM). So, for example,
  on the headland, the speed of the blower
  fan drive can be reduced automatically by the
  implement resulting, apart from additional
  fuel saving in a clear reduction of noise level.

  1
  Improved placement quality due to the higher dynamics of electrically powered drives during changing operational conditions (acceleration, braking).
  Limit values defined by the implement can protect the machine from damage by overload.
  Clearly higher dynamics and control quality for rotating drive systems on the machine.
  2
  
  High dynamic cut-out function for the protection of man and the environment on mounted implements is possible when critical situations are reached.
  Drive systems can be actively braked, so that in the case of an emergency, safety is achieved much quicker.
  Elimination of costly hydraulic components (control blocks, valves, oil coolers, etc.).
  
  3
  Reduction of the thermal demands on the oil reservoir in the tractor.
  No need for a permanently circulating oil flow.
  Improved comfort when coupling the implement(less hydraulic connections).
  
  Additional advantages:
