Test and Verify Electrical Motor Efficiency in accordance with Portuguese Guidelines

Test and Verify Electrical Motor Efficiency in Accordance with Portuguese Guidelines

Industrial electric motors are utilized globally to power a wide variety of applications. According to the International Energy Agency (IEA), the car industry consumes up to 70 percent of all industrial energy, 35 percent of all energy used in the commercial and service sectors, and 45 percent of all electricity produced globally. Each hour of downtime caused by a motor failure costs thousands of dollars, illustrating the significance of electric motors to a wide range of industrial processes.

They are the main reason power plants generate greenhouse gases and have a detrimental influence on the environment. In addition, they are principally responsible for the huge rise in power consumption in emerging countries. There is an economic opportunity to increase the energy efficiency of industrial motors by 20 to 30 percent on a global scale, with most payback periods of less than three years. Electric motors account for 15%, or 4.3 billion tons, of the world’s total annual CO2 emissions of 26 billion tons. Increasing energy efficiency is one of the most cost-effective and low-risk strategies for reducing greenhouse gas emissions and stopping the rise in energy usage.

Utilize A Motor That Operates Effectively Because:

Decreased operational costs
A greater distance that is cooler and more peaceful.
Motors with enhanced durability and performance
Lower emissions of greenhouse gases into the atmosphere.

How to Start a Motor:

Typically, electric motors do not convert the entire electrical energy they receive into mechanical energy. Some energy is lost due to friction, windage, and losses in the stator, rotor, and magnetic core. Due to these losses, the performance of the motor is diminishing. Considering how much energy is wasted and how electric motors are utilized in industry, it is evident why and how important it is to analyze energy efficiency and create minimum energy performance standards.

The chosen testing method determines the precision with which efficiency and motor loss are analyzed. There is no universal testing process used in all businesses throughout the world. Despite the simplicity of the concept, it may be challenging to calculate and verify the energy efficiency of a motor using various standards.

Globally Recognized Techniques for Assessing Effectiveness:

The following testing processes are commonly addressed in industrial contexts: IEEE 112-2004 is a standard test procedure for multiphase motors and generators. International Electrotechnical Commission (IEC) Publication 60034-2-1, Tests, 2014. “Methods for assessing the efficiency and losses of rotating electrical machinery.” JEC 37 is the standard set by the Japanese Electrotechnical Committee for induction devices. Standard IEEE 112-2004 IEEE Standard 112-2004

This method comprises ten evaluation criteria for energy consumption efficiency. To choose the most important:

Simple input and output test
Loss-separated testing of input and output.
Testing of two networked devices back-to-back.
The load losses are computed with the help of the smoothed residual losses.
The “Eh-star” method

Three separate types of IEC standard testing exist:

Determining the input and output power of a machine.
Monitoring the power entering and exiting two series-connected devices.
Each machine’s losses were recorded

The Japanese JEC standard 37 test techniques disregard extra load losses. Reducing the energy consumption of a company’s equipment and appliances may save money and help the environment. This is only one of several substantial economic and environmental benefits. We provide motor start analysis services in all major cities, including Lisbon, Porto, Vila Nova de Gaia, and Braga.
