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

Energy Efficiency Regulations

Regulatory Definition

Motor means 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 covered 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;

Types of motors not covered are:

  • 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 motor;
  • inverter-only motor; or
  • submersible motor (a motor that is designed to operate continuously only while immersed).
