Standardization of Electric Motors


Electric motors are commonly used in industrial world is asynchronous electric motor, with the two global standards IEC and NEMA. Asynchronous motor based IEC metric (millimeters), while the NEMA electric motors based Imperial (inch), in applications there is the unit of power in horsepower (hp) or kilowatt (kW).

Electric motors in IEC standards are divided into several classes according to its efficiency. As a standard in the European Union, the division of this class become EFF1, EFF2 and EFF3. For EFF1 class is the most efficient electric motors, at least waste of energy, while EFF3 already may not be used within the EU, because wasting fuel in power stations and will automatically generate the largest carbon sink, thus further polluting the environment.

Applicable IEC standard is IEC 34-1, this is a standard governing the rotating electric-powered equipment. There are plenty of electric motor manufacturers, but only in part truly follow the directives and IEC 34-1 efficiency levels also follow directives from the European Union.

Many producers of electric motors that do not follow IEC standards and European Union so that their products become cheaper and more were sold, many developing countries manjdi market for these products, which in the long-term users of financial squandering, because of the higher electricity bills each year.

Institutions that regulate and ensure the efficiency level is CEMEP, a European consortium set up by the factories are well-known electric motor, with a view to saving the environment by reducing carbon pollution globally, because a lot of wasted power in the use of electrical load.
For example, in an average industrial electricity consumption for electric motors is approximately 65-70% of total electricity costs, so using an efficient electric motor that will reduce overhead costs of production, thus raising product competitiveness, especially with the increase in electricity tariff every year , hence the use of electric motors EFF1 it was time to become mandatory.

  1. You are right Many producers of electric motors that do not follow IEC standards and European Union so that their products become cheaper and more were sold, all the information is useful that you have added in this post Standardization of Electric Motors.
