DC Motors for Oil Drilling Rigs

The Z490/390 and ZLC490/390 DC motors for oil drilling rigs are manufactured using technology introduced from General Electric Company (GE) of the United States. Based on this technology, the ZS490/390, ZL490/390, and ZL2490/390 series DC motors for oil drilling rigs have been developed, primarily used to drive the rotary table, drawworks, and mud pumps of oil drilling rigs. They are also suitable for top drive drilling systems and other appropriate applications. This series of motors adopts Class H insulation, featuring excellent performance, compact structure, light weight, and reliable operation. They are suitable for thyristor power supplies (without the need for filter reactors) and can be used in onshore, offshore, and desert environments.
