Power electrification boosts efficiency of agricultural machines
At the Agritechnica 2015 show Sensor-Technik Wiedemann (STW) demonstrated its comprehensive portfolio of products, systems and services for power electrification in and around a 'transparent tractor.' The system offers optimum operation of the diesel engine and a driving speed and torque that are independent of the diesel engine speed.
With the powerMELA concept, STW offers individual components for power electrification. And with its ESX series control units, sensors, telematics platforms, and central electric systems for power distribution and operating units, STW says it can deliver unrivalled systems.
While the diesel engine works at an optimum speed and efficiency, electrical energy is generated by a crankshaft generator. This can be utilised directly via a 600V DC network by the powerMELA electrical machines for drives. Electrical energy, which flows back in to the system through regeneration, is put into intermediate storage in a battery. The efficient use of this energy is guaranteed through the powerMELA Battery Management System (BMS). When required, the battery supplies additional energy for the drives and supplies other electrical loads within and on the tractor via DC/AC inverters or DC/DC transformers and central electric systems. In comparison with systems using hydraulic components and PTO shafts, the overall system not only provides a high degree of efficiency, but also ensures a longer lifetime and lower failure rates through the ideal operation of all components.
The control of the engine and driving speed and the control of the speed of attachments takes place via appropriate operator interfaces.
For customers wanting to adopt performance electrification, STW offers a starter kit and can then design of a system tailored to the customer's requirements.
