Mechanical metering functions

Motor torque

Calculates the amount of rotational force (displayed in lb.ft or Nm) developed by a motor and transmitted to a driven mechanical load. The motor torque is the single most critical variable that characterizes the instantaneous mechanical performance of rotating equipment driven by electric motors.

Motor speed

Provides the instantaneous motor shaft rotational speed. Combined with the motor torque, motor speed provides a snapshot of the mechanical performance of rotating equipment driven by electric motors.

Motor mechanical load

Measures the actual mechanical power (displayed in hp or kW) produced by motors and provides a direct link to overloading conditions without simply basing it on the motor current.

Motor efficiency

Shows the effectiveness of each motor within a machine, assembly line, plant, and/or facility in converting electric power to useful mechanical work. By properly aggregating the efficiencies of a population of motors the total (aggregate) efficiency can be estimated. Comparisons to expected motor efficiencies at observed operating conditions can help quantify the cost associated with motor energy inefficiency.

How it works

Using proprietary algorithms, this power quality and motor analyzer uses three phase current and voltage waveforms to calculate motor torque, speed, load and efficiency at a 1 second update rate. The motor air gap field, as observed via the voltage/current waveforms, provides the basis for the measurements. Mechanical sensors and intrusive no-load motor testing is not required, making it faster than ever to analyze overall electric motor performance.

3 power quality and motor analyzer electrical motor analysis

Provides a complete breakdown of electrical parameters. Prior to beginning motor analysis, it's recommended to make base line power quality measurements to assess the state of harmonics and unbalance on the electrical service output as these two properties can have a serious negative impact, on motor performance.

When in Motor Analysis mode, results are summarized for electrical performance, mechanical performance and derating (according to NEMA recommendations).

The easy to understand four-level color severity scale indicates motor performance in relation to the recommended electrical parameter levels including rated power, power factor, unbalance and harmonics.

For mechanical power you can instantly view the mechanical output power along with motor torque and speed. The mechanical output power is instantly compared with electrical power to provide you with live efficiency measurements. With this feature you can easily measure machine performance during each operation cycle.

The NEMA derating screen is updated as the load and the electrical conditions change, and each new measurement is plotted on the tolerance graph as a "+". In this example we can see that motor is within tolerance but is close to the service factor. This indicates that there may be a need for power quality mitigation, motor maintenance or some other performance improving adjustment. By frequently performing these tests over time, known benchmarks and performance trends can be created, enabling informed maintenance investment decisions.

Here are FOUR KEYS to understanding overall motor efficiency and system performance

1
Poor power quality has a direct correlation with motor performance

Power anomalies such as transients, harmonics, and unbalance can cause critical damage to electrical motors. Power anomalies such as transients and harmonics can be detrimental on motor operation. Transients can cause serious damage to motor insulation and can also trip overvoltage circuits, causing monetary losses. Harmonics, which create distortion of both voltage and current have a similar negative impact and can cause motors and transformers to run hot, potentially leading to overheating, or even failure. In addition to harmonics, unbalance can occur in both voltage and current, and is often the root cause of elevated motor temperature and long term wear including burnt windings. Using three-phase measurements on the motors input, technicians capture the broad range of data that can help indicate the overall state of power quality health helping them better troubleshoot the root causes of motor inefficiency.

2
The impact of torque on overall performance and efficiency

Torque is the amount of rotational force developed by a motor and transmitted to a driven mechanical load, while speed is defined as the rate at which a motor shaft is rotating. A motors torque, measured in pound feet (lb ft) or Newton meters (Nm), is the single most critical variable that characterizes instantaneous mechanical performance. While traditionally mechanical torque has been measured with mechanical sensors, the Fluke 438-II calculates torque using electrical parameters (instantaneous voltage and current) in combination with motor rating plate data. Measuring torque can give a direct insight in to the state of health of the motor, the load and even the process itself. By ensuring the motor is running at the torque level within the stated specification ensures reliable operation over time and minimizes maintenance costs.

3
Motor rating data and expected performance

Motors are classified by NEMA (National Electrical Manufacturers Association) and IEC (International Electrical Commission) rating data. These ratings include key electrical and mechanical parameters such as rated motor power, full load current, motor speed, and nominal full load efficiency and provide a description of the overall expected motor performance under normal conditions. Using sophisticated algorithms, modern motor analysis tools are able to compare three-phase electrical measurements with the rated values to provide insight into the motors performance under real load conditions. The difference between running a motor within the manufacturer’s specification or outside those parameters is significant. Running motors in mechanical overload conditions causes stress to motor components including bearings, insulation and couplings decreasing efficiency and leading to premature failure.

4
Motor efficiency has a direct impact on the bottom line

More than ever, industry is striving to reduce energy consumption and increase motor efficiency through “green” initiatives. In some countries these green initiatives are becoming law. One recent study said motors consume 69 % of all industrial electricity and 46 % of all global electricity consumption. By identifying poorly performing or faulty motors and either repairing or replacing them, you keep energy consumption and efficiency in check. Power quality and motor analysis provides data to identify and confirm excess energy consumption and inefficiencies. Plus, the same analytics can verify the improvements upon repair or replacement. In addition, knowing the condition of motors and being able to intervene before failure also reduces exposure to potential safety and environmental incidents.
