YB3 series (compact design) high-voltage and high-efficiency explosion-proof three-phase asynchronous motor inherits the advanced concepts of international high-voltage and high-efficiency medium-sized motor design and manufacturing, combined with the company's long-term technology and experience in developing high-voltage compact motors, and adopts proven and reliable new Developed with technology, new materials and new processes. The products are well manufactured, have excellent performance and operate reliably. YB3 (compact design) motors have greater improvements and improvements than the original YB3 series motors.
This series of motors can be used in petroleum, coal, chemical industry, metallurgy, electric power, oil and gas pipelines, mines, ports, machinery industry and other places where there is an explosive mixture of flammable gas or steam and air. It is used to drive pumps, fans, compressors, conveyors, mixers, crushers, winches and other mechanical equipment. It is an ideal driving equipment.
