Professionals often think if a motor sounds like it’s working, then systems must be in order. However, this assumption is far from the truth. Motor failures can happen when your team least expects it.
(read more)Without regular maintenance, electric motors are prone to wear and tear. Industries that use machines 24/7/365 creates stress on connections, fuses and bearings. Even new motors can suffer from power surges and can put you out of commission for weeks.

(read more)A 398 KW MV motor that runs a blower fan in a cement plant was showing strange behavior. The vibration equipment indicated vibration amplitudes that became chronic with the passage of time. The maintenance team not knowing what the issue was, ran the motor until the bearings had to be replaced. This happened several times with no remedy or cause for the bearing failures. On a few occasio...

(read more)The quickest and easiest way to obtain an overall condition of a motor and compare it's condition over time is using the IND Test available on the AT34, AT7, and AT7 Pro.
Named for its comprehensive, 'industrial-like' strength, the IND Test measures impedance, inductance, phase angle and current frequency on 5 frequencies within 3 minutes. The measurements of each property can be vi...

(read more)Voltage unbalance degrades the performance and shortens the life of a three-phase motor. Voltage unbalance at the motor terminals can cause current unbalance that is far out of proportion to the voltage unbalance. Unbalanced currents lead to torque pulsations, increased vibrations and mechanical stresses, increased losses resulting in lower efficiency, and motor overheating, which reduce...
(read more)ONLINE MOTOR TESTING WITH ELECTRICAL SIGNATURE ANALYSIS
Electrical Signature Analysis (ESA) is an on-line test method where voltage and current waveforms are captured while the motor system is running and then, via a Fast Fourier Transform (FFT), a spectral analysis is done by the provided software. From this FFT, faults related to incoming power, the control circuit, the motor it...

Electric vehicle (EV) powertrains are much simpler compared to traditional combustion engines. These motors do not require the normal service such as oil changes, spark plug, fuel and oil filter maintenance. Electric motors are generally reliable, long-lasting and easy to maintain. Even though...

ENERGIZED ELECTRICAL SIGNATURE ANALYSIS (ESA) TESTING INSTRUMENT. The All-Test Pro On-Line III (ATPOL III) power quality and electric motor analyzer is the most complete electrical signature and power analysis instrument for AC/DC motors, generators, and transformers.
(read more)Many industries, including wastewater, steel, automotive and power generation industries, use electric motors to sustain production processes by converting inputs into mechanical power. Electric motor systems contain dozens, if not hundreds, of parts vital for business operation. Preventative motor testing measures are necessary to ensure your daily responsibilities continue.
(read more)Electrical Signature Analysis (ESA) is a predictive maintenance (PdM) technology that uses the motor’s supply voltage and operating current to identify existing and developing faults in the entire motor system. These measurements act as transducers and any disruptions in the motor system cause the motor supply current to vary (or modulate). By analyzing these modulations, it...
