Flameproof motor YBX3 series

three-phaseasynchronous380 V

YBX3 series high efficiency flameproof three-phase asynchronous motors, its explosion-proof performance meets the requirements of GB3836.1-2010 "Explosive environment Part 1: General requirements of equipment' and "GB3836.2-2010 Explosive environment Part 2: Equipment protected by flameproof enclosure"d". As general driving force, are suitable for flammable gases containing certain components or explosive mixtures of steam and air. They are mainly used in petroleum, chemical and other industries, also in textile, metallurgy, city gas transportation, grain and oil processing, paper, medicine and other industries. The motor efficiency is in accordance with Class 2 of GB18613-2012 Energy efficiency limit value and energy efficiency rating of small and medium-sized three-phase asynchronous motor.The remarkable characteristics of the motors are high efficiency, energy saving,Iarge temperature rise margin, long life, low vibration, low noise and reliability. The motor can also be equipped with auxiliary equipment such as winding temperature sensor, bearing temperature sensor, temperature transmitter and heater accord- ing to user needs. Explosion-proof marks The explosion-proof marks are Exd II AT4 Gb and Exd II BT4 Gb. Structure The degrees of protection: IP55; Cooling type:IC411; Insulation class:F.
