Oil Drilling

Yongji oil drilling motors can meet various installation requirements on oil drilling rigs. The motors can be divided into two series, YZ and YJ (AC or DC). The YZ DC motor has separate excitation and series excitation. The YJ asynchronous motor has frequency control of motor speed. Rated power can be from 250 to 2000 HP (200kw to 1600kw). Different grades of rated power can be supplied according to the needs of users. At present, these motors are installed on drilling rigs with drilling depth from 3,000 ft to over 20,000 ft.
