Depending on its advanced desiging technique and ripe experience in production, Yonge has developed and produced the oil drilling motors with electric transmission since 1998 on the premise of introducing GE's technology on electric machine and electric control devices from USA. These motors can meet various installing requirements on oil drilling rig with electric transmission. The motors can be devided into two series. One is the YZ DCmotor with separate excitation and series excitation, the orther is the YJ asynchronous motor with frequency control of motor speed. Its rated power can be from 200kw to 1600kw(different grades of rated power can be supplied according to the needs of users). At present, these motors are installed on the drilling rigs with drilling depth from 1000m to 7000m.

ZQDR-310 Traction Motor we manufactured can be interchanged with GE761A19 and has been exported to America, Nigeria, Pakistan etc. Now we can supply Traction Motors which can be interchanged with GE761AA14, 15, A19, A23 GE752AF8 and D29cct Traction Motor etc.

Now, Yonge is indraughting technology from SIEMENS(Germany), EMD(U. S. A), ALSTOM(France), TOSHIBA(Japan) and HITACHI(Japan).

Yonge has been certified in conformity with the ISO9001quality control system and ISO14001 environmental management system carried out by both internal and external organizations.
