Product Overview<\/h2>\n

The YE2 (also designated IE2 under the international efficiency classification) is a cast-iron-housing three phase motor<\/b> built from a clean-sheet design optimized for energy efficiency. It reaches IE2 (high efficiency) levels across the full power range \u2014 from a compact 0.18 kW unit for instrument drives all the way up to 450 kW units powering industrial blowers and centrifugal pumps. Compared to older Y and Y2 series motors that populated Korean factories for decades, the YE2 delivers the same mechanical output while drawing measurably less current from the supply, thanks to improved stator and rotor lamination steel, optimized slot geometry, and tighter manufacturing tolerances on the air gap.<\/p>\n

\"YE2-IE2Series<\/p>\n

The cast-iron housing gives the YE2 a durability advantage in heavy industrial settings where aluminum frames might suffer physical damage from forklift traffic, falling objects, or chemical exposure. Iron castings also provide superior vibration damping \u2014 the higher mass and stiffness of iron naturally absorbs rotor-induced vibration before it reaches the machine frame. This characteristic matters on precision equipment such as CNC lathes, surface grinders, and coordinate measuring machines where even micro-level vibration can affect workpiece quality.<\/p>\n

Korea Ever-Power stocks the most commonly ordered YE2 models at our regional warehouse, enabling single-week delivery for urgent replacements. For bulk fleet upgrades \u2014 a common request from manufacturing plants replacing entire lines of legacy Y-series ac motors<\/b> \u2014 we offer project pricing and coordinated delivery scheduling that aligns with your planned shutdown windows.<\/p>\n

Core Advantages of the YE2\/IE2 Motor<\/h2>\n

The YE2 platform was designed to hit a specific sweet spot: higher efficiency than legacy motors, rugged enough for the worst factory environments, and priced to make fleet-wide upgrades financially viable. Here are the practical strengths that Korean buyers value most.<\/p>\n

    \n
  1. IE2 Efficiency Across the Full Range<\/b> \u2014 Every model from 0.18 kW through 450 kW meets or exceeds IE2 thresholds under IEC 60034-30-1. On a 30 kW motor running 6 000 hours per year, the efficiency gain over an older Y-series motor saves approximately 3 000 kWh annually \u2014 enough to pay back the price difference within 12 to 18 months at typical Korean industrial electricity rates.<\/li>\n
  2. Cast-Iron Durability<\/b> \u2014 The gray cast-iron housing handles the knocks, vibrations, and chemical splashes of real factory floors. Unlike aluminum alternatives, iron does not dent from incidental contact and offers natural corrosion resistance when properly primed and painted. The standard finish passes a 300-hour salt-spray test.\"YE2_IE2<\/li>\n
  3. Low Vibration and Noise<\/b> \u2014 Precision rotor balancing (ISO 21940-11 Grade G2.5) and optimized fan blade profiles keep both mechanical vibration and airborne noise below the limits set by IEC 60034-14 Grade A. Workers on adjacent stations benefit from a quieter environment, and vibration-sensitive downstream processes run more consistently.<\/li>\n
  4. Strong Starting Torque<\/b> \u2014 The YE2 retains a high locked-rotor torque ratio (Tst\/Tn up to 2.2 on most models) despite the improved efficiency. This means the motor can start heavy loads \u2014 loaded conveyors, positive-displacement pumps, screw compressors \u2014 without requiring a reduced-voltage starter or a VFD for the start-up phase alone.<\/li>\n
  5. IEC-Standard Frame Dimensions<\/b> \u2014 Foot mounting holes, shaft diameters, and flange patterns follow IEC 60072. The YE2 drops directly into mounting positions designed for any IEC-compliant motor of the same frame size, including older Y and Y2 series units.<\/li>\n<\/ol>\n

    <\/p>\n

    Energy Efficiency and Cost Savings<\/h2>\n

    Replacing an older electric motor<\/b> with the IE2-rated YE2 generates real, measurable savings. The magnitude depends on motor size, load factor, operating hours, and local electricity price. Below is a worked example for a typical Korean manufacturing scenario.<\/p>\n

    \n

    Example: 30 kW Pump Motor Replacement<\/p>\n

    Old motor (Y-series): efficiency 89.0 % at full load<\/p>\n

    New motor (YE2): efficiency 92.3 % at full load<\/p>\n

    Operating hours: 6 000 h\/year at 85 % average load<\/p>\n

    Electricity price: 120 KRW\/kWh (approx. USD 0.09)<\/p>\n

    Annual energy saved: approximately 3 200 kWh<\/p>\n

    Annual cost saved: approximately 384 000 KRW (USD 290)<\/p>\n<\/div>\n

    At 384 000 KRW saved per motor per year, a plant replacing 20 old motors recovers the entire purchase cost of the new YE2 fleet within roughly 18 months. After that payback period, the savings flow directly to the operating budget. For plants running three shifts (8 000+ hours per year), the payback period drops to about 12 months. These calculations use conservative full-load figures; actual savings at partial load may be slightly higher or lower depending on the specific load profile. Our engineering team can provide a customized energy-savings estimate based on your actual operating data \u2014 send us your motor nameplate photos and average load readings, and we will return a detailed payback analysis within two business days.<\/p>\n

    Selection Guide for High Efficiency AC Motors<\/h2>\n

    Picking the right YE2 model for your application involves confirming a handful of key parameters. Getting these right at the quotation stage avoids costly returns and re-orders later.<\/p>\n

      \n
    1. Output Power<\/b> \u2014 Determine the mechanical power (kW) your driven equipment requires at its operating point. If replacing an existing motor, check whether the old unit was oversized \u2014 running a motor below 50 % load reduces both efficiency and power factor. Right-sizing the replacement to match the actual load improves overall system efficiency.<\/li>\n
    2. Supply Voltage<\/b> \u2014 The performance table lists rated currents at 380 V, 400 V, and 415 V. Confirm your facility supply voltage and select the matching column. For 440 V or 480 V supplies common in some Korean industrial parks, request a custom winding specification.<\/li>\n
    3. Pole Count and Speed<\/b> \u2014 2-pole (3000 r\/min), 4-pole (1500 r\/min), 6-pole (1000 r\/min), and 8-pole (750 r\/min) variants are available. Match the motor speed to the driven equipment requirement, accounting for any gearbox ratio in the drive train.<\/li>\n
    4. Mounting Configuration<\/b> \u2014 The YE2 supports B3 (foot mount), B5 (flange mount), and B35 (foot + flange) arrangements. Confirm the mounting type used on your existing installation to avoid modification work.<\/li>\n
    5. Environment<\/b> \u2014 Standard YE2 motors are rated for ambient temperatures up to 40 \u00b0C and altitudes up to 1 000 m. High-altitude or high-temperature applications require derating or enhanced cooling arrangements.<\/li>\n<\/ol>\n
