IE3 Series high -efficiency three phase asynchronous motors are based on the latest development of fully enclosed self-fan air-cooled squirrel cage ultra- high-efficiency Three-phase asynchronous motor based on GB/T28575-2012.. The 3- level energy Efficiency level in the "energy Efficiency Limit Value and Energy EFFICIENCY levels of asynchronous Motors is in line with IE3in the energy efficiency level in IEC60034-30, And it is in the first- class level with the most advanced American NEMA ultra-efficiency Motor. Compared with IE2 series. IE3 series high efficiency motor is more energy saving.low carbon and environment protection. The installation size,power level and ordinary motor are exact the same, in line with the International Electro technical Commission IEC60072-1 standard. Can be directly replaced to achieve the purpose of energy saving.,power saving.easy to promote the market.. the motor with the center height H160 and above can be equipped with uninterruppted oil filling and discharging device, and the space for installing thermistor and moisture-proof heating belt is reversed, which is convenient for users to choose . The power range of this series of motors:0.75kw-315kw> the center height of the base:H80-H355.
