Motor and Generator

The electric motor converts electrical energy into mechanical energy. Motors convert approximately 50% of all electricity into motion for driving modern society. Products consist of motors rated from 1/1,000 up to 50,000 HP and rated up to 13,800 volts. They include fractional horsepower (HP) motors, medium AC and DC machines, and large AC and DC machines.

The NEMA Premium® energy efficiency motors program, the first verification program of its kind for motor efficiency, is often specified in commercial, industrial, and government contracts to help purchasers optimize motor systems efficiency, reduce electrical power consumption and costs, and improve system reliability.

As the voice of the industry, Members collaborate with regulators, other trade associations, and other electroindustry stakeholders to develop standards and policy.
