PTO Generator driven electrical components for various agricultural usage

摘要

A developed and constructed power take-off generator is used as a mobile electrical power supply. It is possible to operate asynchronous motors in open loop mode and permanent magnet synchronous motors in closed loop mode. Furthermore it is also possible to apply AC-Voltage, 3×400 V and 1×230 V, to use external electrical appliances. These four types are described and measurements are presented. Besides the possibility for constant DC link voltage independent of the PTO revolutions are shown. Additionally test bench results of sensorless drives in agriculture purpose show the potential for operating such devices in that manner.
