Product Introduction
It is designed according to the explosive gas atmosphere place which has high repuirements on reliability and performance of the safety, such as petroleum, petrochemical, oil and gas pipelines, chemical, coal.
Flameproof motor used for coal mine must conform to the coal mine safety requirements. Based on the design optimization of the stator, rotor and fan, motors loss value is controlled at the lowest level. The efficiency satisfy GB18613 limited values of energy effciency and level for small and medium three-phase asynchronous motors, energy-saving project and the requirements of high efficiency in petroleum and petrochemical industry. On the basis of YB3 series motor, YB3-W outdoor type,YB3-TH steaming tropic type. YB3-THW outdoor steaming tropic, type, YB3-TA dry tropical type, YB3-TAW outdoor dry tropical type. YB3-T tropical type, YB3-TW outdoor tropical type and YB3-WF1 outdoor medium corrosion type and other climate conditions types can also be made.
