On a global scale, industrial electric motors are utilized to power a variety of applications. The worldwide energy consumption of the automobile industry is estimated by the International Energy Agency (IEA) to be up to 70% of all industrial energy, 35% of energy used in the commercial and service sectors, and 45% of all electricity generated. Many industrial processes depend on electric motors since each hour of downtime caused by a motor failure costs thousands of dollars.
They are mostly responsible for power plants’ harmful environmental consequences and greenhouse gas emissions. They are also largely to blame for the significant increase in electricity usage in developing nations. Industrial motor energy efficiency may be increased by 20% to 30% globally, with typical payback times of under three years. Around 15%, or 4.3 billion tons, of the world’s annual CO2 emissions, which total 26 billion tons, are controlled by electric motors. Increasing energy efficiency is one of the most cost-effective and low-risk solutions to reduce greenhouse gas emissions and halt the growth in energy use.
Employ A Working Motor Because:
Typically, electric motors do not convert all of the electrical energy they receive into mechanical energy. Windage, losses in the stator, rotor, and magnetic core, as well as friction, all result in some energy being wasted. These losses are lowering the performance of the motor. When you consider how much energy is consumed and how electric motors are used in industry, it becomes clear why and how crucial it is to look at energy efficiency and develop minimal energy performance standards. Efficiency and motor loss are measured more properly or inaccurately depending on the testing method. Global businesses don’t all employ the same testing technique. Although the concept is simple, it could be difficult to evaluate and certify a motor’s energy efficiency using different criteria.
In industrial environments, the following testing methodologies are frequently used: The IEEE (Institute of Electrical and Electronics Engineers) 112-2004 standard is frequently used for testing multiphase motors and generators. The International Electrotechnical Commission (IEC) publication 60034-2-1, “Methods for Calculating Efficiency and Losses in Rotating Electrical Machines,” was published in 2014. The Japanese Electrotechnical Committee created JEC 37 as the benchmark for induction devices. IEEE Standard 112-2004 IEEE Standard 112-2004
Ten measures are used in this process to assess energy consumption effectiveness. To determine which is most crucial:
IEC standard testing is available in three formats:
The test procedures do not change because of the additional load losses, according to Japanese JEC standard 37. Businesses may reduce the amount of energy used by their machinery and appliances, which can result in cost savings and environmental benefits. This is only one of the many significant economic and environmental benefits. All of the major cities, including Stockholm, Gothenburg, Malmo, and Uppsala, receive our motor start analysis services.
