Product Description
YB3 series high-efficiency flameproof three-phase asynchronous motor is a fully enclosed, self-fan cooling high-efficiency motor. This series of products replaces the original YB2 series flameproof three-phase asynchronous motor, and its efficiency meets the requirements of GB18613-2012 energy efficiency grade 3 standard.
This series of products has the characteristics of excellent performance, safe and reliable use, low vibration and low noise, and meets the requirements of environmental protection; its production equipment adopts advanced CNC machine tool equipment, adopts advanced insulation structure design and manufacturing process, and adopts high-quality cold-rolled silicon steel. Sheets and high-quality bearings that have undergone strict quality inspection and control.
The explosion-proof performance of YB3 series motors meets the requirements of GB3836.1-2010 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" and GB3836.2-2010 "Electrical Equipment for Explosive Gas Environments Part 2: Flameproof "d"" Regulations, applicable places: ExdⅡBT4Gb is suitable for factories with Class II Class B, and the temperature group is the environment where explosive gas mixtures of Group T4 exist. place.
