Features & Benefits

N/A

  • GEGARD1800™ Insulation System
    The GEGARD1800 insulation system exceeds NEMA MG1-31 standards for motors operating on Inverter power at 460 or 575 volts. Other inverter capabilities include a 10:1 variable torque speed range along with a 4:1 constant torque.
  • Energy Savings
    The Energy $aver TEFC meets US Government EIS Act efficiency levels and also meets NEMA Premium efficiency levels. This motor design has been tested per IEEE 112 Method B to ensure those efficiencies are met. Because of this, energy savings vs. a Pre-EPACT or EPACT motor are significant. For instance, a 100 HP PreEPACT 4 Pole TEFC motor operating 8760 hrs/yr at a rate of $0.06/kWH replaced with a similar Energy $aver TEFC-SD will save you over $1800 every year in energy costs!
  • Severe Duty
    The Energy $aver frame, end shields, fan cover and conduit box are a rugged cast iron construction. It includes a recessed steel reinforced neoprene sling to minimize contaminants from entering the bearing cavity. Additional HP is available at 1.15 service factor for severe applications. A non-hygroscopic, anti-fungus Class F insulation is included, with an 80°C (NEMA B) temperature rise. A 0.08 in/sec vibration meets the IEEE 841 Standard and Y-Start/Delta Runs are designed for 210-320 motor frames.
