Audit Motor Efficiency and Reliability for Commercial Use in Australia

The cleanest, cheapest, and fastest way to get reliable power is improving energy efficiency. The total electricity consumed by motors is 46% approximately and 69% of the energy consumed in the industrial sector.

One of the main issues facing several industries is energy consumption. The poor design and improper use of the electricity is still the main concern which needs to look. Poor design and improper use are the prominent reasons for the high electric bills, and struggles to meet excessive demand of power.

Most motors run at speed 50% to 100% of rated loads while the maximum efficiency is 75% of rated load, this starts decreasing with certain ages. An electric motor efficiency tends to decrease automatically after 50% load.

Poor power quality has a direct correlation with the performance of motor: Power quality issues such as transient, unbalance, sags, swells, and harmonics can cause critical damage and sometimes malfunction.

The impact of torque on efficiency and overall performance: when a motor developed a rotational force to drive a mechanical load at the rated speed of the rotating shaft. The electric motor runs at torque-speed at rated frequency ensures reliable operation. Measuring torque gives a direct insight into the condition of the electric motor.

The electric motor running data and its performance expectation: Operating motor at mechanical overload create stress to motor components including coupling, bearing and insulation reduce efficiency and lead to malfunction or premature fail.

Bottom line direct effect of motor efficiency: Collecting baseline data is the first step of predictive and preventive maintenance.

75% cases of motor failures in industries result 1-6 days of plant downtime a year. Out of 75% cases of motor failures, 90% of the 50hp motor failure occurred in less than a month warning while 36% motor failures within a day warning.

To avoiding motor failure and malfunction problems performing assessment, analysis, inspection, or audit at regular intervals can help you to mitigate all the problems related to the electrical motor and improve motor efficiency as well as reliability.
