How to evaluate efficiency and dependability of commercial motors?

Improving energy efficiency is the cleanest, cheapest, and quickest way to get reliable power. Motors consume approximately 46% of total electricity consumed and 69% of total energy consumed in the industrial sector. Energy consumption is one of the most pressing issues confronting many industries. The main concern that needs to be addressed is the poor design and improper use of electricity. Poor design and improper use are the primary causes of high electric bills and struggles to meet the excessive demand for power. Most motors operate at 50% to 100% of the rated load, while the maximum efficiency is 75% of the rated load, which begins to decline with age. After 50% load, the efficiency of an electric motor tends to decrease automatically. 

Four Factors Influencing Motor Efficiency: 

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

The effect of torque on efficiency and overall performance: when a motor generates rotational force to drive a mechanical load at the rotating shaft’s rated speed. The electric motor operates at torque speed at the rated frequency, ensuring dependable operation. Torque measurement provides a direct indication of the condition of the electric motor. 

The electric motor running data and its expected performance: Operating the motor at mechanical overload causes stress to motor components such as the coupling, bearing, and insulation, which reduces efficiency and leads to malfunction or premature failure. 

Bottom line direct effect of motor efficiency: The first step in predictive and preventive maintenance is to collect baseline data. 

75% of industrial motor failures result in 1-6 days of plant downtime per year. Out of 75% of motor failures, 90% occurred within less than a month of warning, with 36% occurring within a day of warning. To avoid motor failure and malfunctioning issues Regular assessments, analyses, inspections, and audits can assist you in mitigating all electrical motor problems and improving motor efficiency and reliability.

Stats on Increasing Motor Efficiency: 

Increase the efficiency of an induction motor by 68% over a 53-year period (1960 to 2013). Induction motor energy efficiency has improved over the years (data of 45 kW, 4p design motor). Care Labs audits electrical motor efficiency and reliability for a variety of commercial facilities and industries.
