High-efficiency motors are more efficient motors whose efficiency should meet the relevant energy efficiency rating requirements. Efficient motors take measures from design, materials and processes, such as reasonable positioning, rotor slot number, fan parameters and sinusoidal windings to reduce losses, and efficiency can be increased by 2%-8%, with an average increase of 4%.
High efficiency motor features:
(1) High efficiency, IE2 is 3% higher than IE1, and IE3 is about 5% higher than IE1.
(2) More energy-saving materials are needed. IE2 costs 25% to 30% more than IE1 motors, and IE3 costs 40% to 60% more than IE1 motors.
(3) Due to the lower operating temperature, the motor has a longer life and can reduce maintenance costs.
(4) The starting current is larger under typical design conditions.
(5) The rotor inertia is large.
(6) High speed at rated load, small slip rate
YE2 series high-efficiency motors are high-efficiency motors with cold-rolled silicon steel as the magnetic conductive material. The YE2 motor is a fully enclosed self-fan cooled squirrel-cage high-efficiency three-phase asynchronous motor. The efficiency index of this series of motors reaches the level 3 energy efficiency rating in China GB18613-2012 "Small and Medium-sized Three-Phase Asynchronous Motors Limited Value and Energy Efficiency Rating". YE2 high-efficiency motor has high efficiency and various performance indicators have reached the international advanced level. The motor is used to drive long-running loads such as fans and pumps, which is energy efficient and saves energy.
The installation size and power level of YE2 high-efficiency three-phase asynchronous motor conforms to the International Electrotechnical Commission IEC72-1 standard. The center high H160 and above motor is equipped with non-stop injection oil discharge device, and space for installing the thermistor and moisture-proof heating belt is reserved. It is convenient for users to choose. The motor stator adopts Class F insulation, but the temperature rise is evaluated according to 80K, the motor temperature rise is low, and the service life is long; the rotor adopts the cast aluminum process, and the running reliability is high.
