| Abstract: | This paper presented an application probability to adjust Rat-cage motorspeed by variable frequence on Current Source Inverter in multi-motorssystem of print and dying combine. Master motor realizes to adjust speed inconstant torque under normal speed and in constant power above normalspeed. The operation of slave motor depends on the control schemes. Itsoperation state is same as state of master motor essentially in independentD.C supplies or always in the weak magnetic field manner in common D.Ccurrent supply. |
