As to the electric system, we compared the DC rig123.net' target='_blank'>SCR drive rigs and AC converter drive rigs deeply, we recommend AC (AC-VFD-AC)converter drive rigs due to the following advantage of AC Converter drive rigs.
1， AC Converter drive rigs has the advantage of low speed start and maintenance, it has good performance in low speed running and operation.
2， It has the limitation function of Torque and rotation speed, strong overload protection could avoid the broken of drill pipes and other main parts.
3， Higher efficiency than DC SCR drive rigs.
4， High stability, none carbon brush and commutator, lower motor maintenance cost than DC SCR drive rigs.
5， It has brake assist function, no need equip magnetic electric eddy brake, simplify the drawworks structure with lower weight.
6， Main motor automatic bit feed.
7， Simplify the variable frequency speed regulation system of Drawworks and Rotary Table with stepless speed regulation.
etc.
AC Drive Rig may little expensive than DC, but its advantage with good performance and lower operation cost should be a good choice for buyer.
