Electric motors (1 to 500 HP/0.746 to 375 kW)

Energy Efficiency Regulations

Regulatory definition

Electric motor, a machine that converts electrical power into rotational mechanical power, including any motor that is incorporated into another product - whether or not that other product is an energy-using product, and that:

• is an electric three-phase induction design
• is one of the following designs:
  • a NEMA design A, B or C with a three- or four-digit NEMA frame number
  • an enclosed NEMA design A, B or C with a NEMA frame number of 56, or
  • an IEC design N or H with an IEC frame number of 80 or above
• has a nominal output power of not less than 0.75 kW (1 HP) and not more than 375 kW (500 HP)
• has a cage or squirrel-cage design
• is rated for continuous duty or S1 operation
• is designed to operate at a single speed
• has a nominal voltage of not more than 600 V AC
• has a nominal frequency of 50 Hz, 50/60 Hz or 60 Hz
• has a two-, four-, six- or eight-pole construction
• has an open or enclosed construction, and
• has an IP code from 00 to 67

Types of motors include:

• close-coupled pump motor
• fire pump motor
• integral gear assembly
• partial motor
• totally enclosed non ventilated motor (TENV)
• brake motor
• motor with separately powered blower
• vertical solid shaft motor
• vertical hollow shaft motor
• immersible motor (a motor designed to operate continuously in free air, but can operate continuously for a period of at least 30 minutes while completely submerged)
• explosion proof motor, or
• motor with sleeve bearing, thrust bearing, non-standard base, non-standard endshields or flanges, encapsulated windings, moisture resistant windings or sealed windings

Does not include:

• air-over motor (a motor that is cooled by air that is forced over the motor by a fan or blower that is not an integral part of the motor)
• liquid-cooled motor
• component sets of a motor
• inverter-only motor, or
• submersible motor (a motor that is designed to operate continuously only while immersed)
