Around the world, industrial electric motors are utilized to power a variety of applications. According to the International Energy Agency (IEA), the automotive industry consumes up to 70% of all industrial energy, 35% of all energy utilized in the commercial and service sectors, and 45% of all electricity generated globally. The importance of electric motors in a variety of industrial processes is highlighted by the fact that each hour of downtime caused by a motor failure costs thousands of dollars.
They are the main source of greenhouse gases, which have a negative impact on the environment, released by power plants. They are also primarily to blame for the enormous rise in electricity consumption in emerging nations. Globally, there is a financial potential to boost industrial motor energy efficiency by 20% to 30%, with typical payback times of less than three years. 15%, or 4.3 billion tons, of the global CO2 emissions are produced by electric motors. One of the most economical and low-risk ways to reduce greenhouse gas emissions and halt the rise of energy consumption is to increase energy efficiency.
Make advantage of a working motor because
Not all electrical energy is converted into mechanical energy by electric motors. Friction, windage, and losses in the stator, rotor, and magnetic core all result in some energy being wasted. These losses result in a decrease in the motor’s performance. You can understand why and how crucial it is to assess energy efficiency and set minimal energy performance criteria when you look at how much energy is consumed and how electric motors are used in industry. The method of testing used impacts how accurately efficiency and motor loss are assessed. There is not a single testing procedure applied by all companies worldwide. The concept is straightforward, but it can be challenging to measure and verify a motor’s energy efficiency using different standards.
In industrial environments, the following testing procedures are commonly mentioned:
For multiphase motors and generators, the IEEE (Institute of Electrical and Electronics Engineers) (Institute of Electrical and Electronics Engineers) 112-2004 test method is frequently used. “Methods for estimating the efficiency and losses of rotating electrical equipment,” International Electrotechnical Commission (IEC) Publication 60034-2-1, Tests, IEC, 2014. The JEC 37 standard for induction devices was produced by the Japanese Electrotechnical Committee. IEEE Standard 112-2004 IEEE Standard 112-2004
Ten parameters make up this method’s evaluation of energy consumption effectiveness. To decide which is most crucial:
IEC standard testing is divided into three categories:
The Japanese JEC standard 37 test methodologies do not consider the increasing load losses. By reducing the energy use of their equipment and appliances, businesses may save money while simultaneously doing their part to protect the environment. This is only one of the important economic and environmental benefits. In all major cities, including Helsinki, Vantaa, Espoo, and Tampere, we provide motor start analysis services.
