Low power YB2-5003-16 proof motor motor stator windings made of high strength polyester enamelled round copper wire, and by VPI vacuum pressure impregnation treated as a complete whole, winding and insulation has good electrical, mechanical, moisture resistant and thermal stability, and marine motor at the end of special anti-bacterial enzyme treatment. 7 rotor cast aluminum structure, rotor balancing after verification, smooth motor operation, small vibration, low noise. 8 motor stator and rotor punching with high permeability, low-loss high-quality electrical steel, motors, low loss, high efficiency. 9 motor bearings use low vibration, low noise bearings, frame size 132 and below, using double-sided sealed bearings in the shaft end fitted with a wave spring washer to moderate pressure by bearing, effectively suppress the vibration and noise generated when the motor is running, Frame sizes 160 and above using the inner and outer cover structure and parts used in the bearing ring axial fixed, effectively prevent axial movement of the motor rotor. Use an electric motor rated voltage condition 1.1: 380,660,1140,380 / 660,660 / 1140V. (Note: 660 / 1140V voltage classes and YB2-355 YB2-315 only have a product) 1.2 Rated frequency: 50Hz. 1.3 Fixed: continuous duty S1. 2 motors use of environmental conditions altitude does not exceed 1000m, ambient air temperature changes with the seasons, for indoor -20 ~ + 40 ℃ environment. YB3 basic type, suitable for indoor environments YB3-W for outdoor environments YB3-TH for indoor environments Humid Tropics YB3-THW suitable for outdoor environments Humid Tropics YB3-TA for dry indoor tropical environments YB3-TAW for outdoor dry tropical environments YB3-T for indoor tropical environments YB3-TW for outdoor tropical environments YB3-WF1 for outdoor moderately corrosive environments YB3-H is suitable for the marine environment YB2-5003 -16 Low power explosion-proof motor
