The power of knowing


MVS ACMEI TECHNOLGIES has partnered with ALL TEST PRO of U.S. to bring the best motor testing tools to our customers in India.
We offer the most advanced predictive maintenance testing & trouble shooting tools for AC motors, DC motors, coils, windings, transformers and generators.

De-energized Motor Testing Products


Significantly increase your plant's profitability with the AT5™ motor circuit analyser, which offers a complete electric motor health analysis in minutes.


The handheld ALL-TEST IV PRO™ (ATIV™) is an excellent analytical instrument for detecting and trending potential winding faults in AC and DC motors, transformers (distribution and transmission), generators, alternators, and other devices with windings.

AT 33 IND™

Two tests in one. The instrument can be used in two modes: static and dynamic. Both quickly collect data in the auto mode and there is no need to operate a lot of difficult to understand buttons.


The AT31™ will measure impedance(Z), phase angle (Fi), current / frequency response (I/F), insulation to ground resistance (500V or 1000V and measure to 500 meg-ohm), will perform a quick pass/fail rotor test (by turning the motor shaft), and will measure EMI.

Energized Motor Testing Products


ATPOL II™ is actually two instruments in one -- a complete Motor Analyzer (ESA) and a complete Power Quality Analyzer (PQ).


The ALL-SAFE PRO® provides the signals necessary to determine a motor's condition with a minimum of risk, error and trouble.

Complete Motor Testing Assemblies

The MD III™ Assembly includes all you need for complete energized and de-energized testing of motors, generators & transformers. Combine the power of Motor Circuit Analysis (MCA™) and Electrical Signature Analysis (ESA) to evaluate and trend yur entire motor system.


THE ATPRO 5™ system combines the analytical and trending power of the hand-held ALL-TEST PRO 5™ and ALL-TEST PRO 21™ tools with the advanced analysis and motor management capabilities of the MCA PRO™ enterprise software.

Case Studies

ATP @ Cardinal Ethanol

In 2008, Cardinal Ethanol commissioned a natural gas fired ethanol producing plant in the heart of the Corn Belt. Located in Indiana, this ethanol plant produces approximately 100 million gallons of ethanol per year, in addition to 340K tons of dried distillers grains with solubles that are distributed to companies who produce food for livestock and poultry. In December 2015, the maintenance team noticed the grain flow was being interrupted. The AT33™ de-energized motor testing instrument, which performs both Static and Dynamic tests, is a proven asset for revealing the complete condition of the motor rotor and stator windings and also helps the maintenance technician or operator understand if there are any issues with contamination, connections, and ground faults.

ATP @ Hospital

A motor distributor in the Netherlands provided a 17 Kilowatt, 400-Volt motor to a local hospital in 2015. The hospital rented a portable crane to install the motor onto the roof of the building. The motor is used to operate a fan that is mounted on the hospital’s roof. In the spring of 2016, the motor suddenly stopped running, so the motor distributor was contacted for field service, troubleshooting, and on-site support. An ALL-TEST PRO 5TM (pictured to the right) was used to perform a de-energized, non-destructive Motor Circuit Analysis (MCA) test at the service providers’ facility.

ESA @ Power Plant Pump

One nuclear power generating facility, located in the Northeastern United States, relies on four vertical service water pumps to feed water to a heat exchanger which cools the sealed ultrapure water/steam that drives the turbine generators. Of the four identical service water pumps, all of which had 30-foot long shafts, two of the pumps began to exhibit some performance issues. The ALL-TEST Pro Online II™ energized motor testing instrument was used to perform the electrical signature analysis.
