Controlled Pyrolysis Oven Improves Repair Process

An important step in rewinding an AC Induction Motor is removal of the defective winding from the stator.  This is typically accomplished by utilizing an oven to raise the temperature of the stator to decompose the winding insulation. The motor winding wire is then easily removed from the stator laminations. Laminations are made from carbon steel and have been processed thru heat treatment and have an insulating coating applied to prevent eddy currents from moving from lamination to lamination.

Flolo utilizes a Controlled Pyrolysis cleaning furnace to remove the insulation such as cured varnish, epoxy and other organic materials from stators and rotors that need to be rewound. Ovens without temperature controls, as well as open flame stripping do not offer a controlled decomposing of the insulation in the way a Pyrolysis oven does. The temperature is controlled by utilizing a probe placed directly on the smallest part being processed to regulate the core temperature within 5 Degrees F of the set point. Should the temperature exceed the set point the controller turns on a water spray mist to cool the parts being processed and slow down the process. The set point is set for a temperature stipulated by the EASA/ANSI standard AR100.

All of these organic materials are removed without flame on the part and the byproducts that become airborne are incinerated in an afterburner to clean the air before exiting the stack. This meets the Illinois EPA clean air requirements.

This process has many positive effects including the prevention of heat damage to the insulation coating of the laminations as well as maintaining the design or pre-repair efficiency in the rewound motor.

Flolo Repair – A Ground Up Transformer Rebuild

Flolo’s repair group does much more than just repairing electric motors.  In fact, we repair a multitude of different items, both electrical and mechanical, including (but not limited to) gearing, electronic drives and pumps.  For instance, this 222kVA transformer was sent to Flolo by a Steel Mill in an obvious state of disrepair.  We tore the old unit apart and rebuilt it from the ground up using only the best quality materials.  This was one of a number of transformers of similar design repaired by the Flolo Corporation.

On-Site Condition Monitoring


Downtime. Everybody needs a little downtime after putting in 40, 50, 60 hours of work during the week. What nobody needs, though, is the unexpected and unwanted downtime caused by a catastrophic failure of an important piece of equipment.

You can now reduce downtime and increase your productivity with onsite condition monitoring. Many companies currently use a broad route based monitoring system commonly referred to as “milk runs”. This method results in a lot of time wasted walking the plant to collect data. And a problem or breakdown can occur immediately after a machine has been checked out.

Onsite condition monitoring consists of selecting the most critical assets in your plant and mounting sensor nodes that monitor temperature, vibration and speed (where applicable). The data can then be accessed from the cloud either through Wi-Fi or cellular communication. For the most part this data can be accessed from any device.

So, how does it work? Flolo will assist you in determining the best candidates in your plant for monitoring. These can include your critical assets that have a very high cost of downtime; hard to read assets in remote locations or areas that present a safety risk for your workers.

Once the monitors are installed it just becomes a matter of collecting via Wi-Fi or a cellular network the information on vibration, temperature and speed (through the use of an encoder). This data will be collected and reviewed by Flolo personnel and partner with customer personnel. A baseline will be set for each piece of equipment being monitored and we will be able to determine when a problem exists and correct it before it becomes a major disaster.

The built-in software tools allow for alarms to be set and real time data can be analyzed. We will be able to analyze with built in tools:

– Real Time waveform analysis (like an oscilloscope display) of the signal from the transducer.

– FFT Display showing the frequencies and the magnitude of the vibration signal at those frequencies.

– A Waterfall plot showing multiple FFT plots on a time scale showing the change in the waveform over time.

– An Harmonic cursor indicating all the harmonics of the base frequency.

Contact your Flolo representative today to start protecting your equipment with onsite monitoring. Or call 630-595-1010 and ask for Customer Service.

Flolo Electricman has returned!

I’ve been brought out of Superhero retirement to help our current and future customers in any way I can. Since Superheroes don’t age, I still look the same as I did some 40 years ago, for those of you who may remember me.

Maximum motor lead length when using AC Drives

All drives are limited with respect to the maximum motor lead length that they can support. This limitation occurs because the drive must supply additional current to charge or discharge cable capacitance. Maximum Cable length recommendations are different for different Series Drives.

The use of an output reactor is usually the most convenient and economical means of minimizing the possibility of motor insulation failure due to the voltage stress caused by the interaction between the inverter waveform, the motor cable and the connected motor.

Here is a series of Best Practices to help mitigate problems caused by excess lead length.

– Always use the lowest Carrier Frequency possible – higher carrier Frequency results in shorter Insulation life.
Example : 150 foot long cable Motor insulation life is reduced from 100000 hours to
25000 hours when carrier frequency is increased from 3 KHz to 12 KHz

– Use Motors that meet NEMA MG-1 Part 31 – with 1600 volt rated Insulation and
Insulation between phases.

– Use VFD Cable – ideally with Symmetrical Ground.

When selecting cable type and wiring methods consult the drive manufacturer’s manuals for their recommendations and the motor manufacturer for their recommendations. Longer cable runs may require an output filter dependent on the drive horsepower and the motor voltage and motor winding’s insulation peak voltage withstand rating.

For help navigating this confusing topic call us at 630-595-1010 and me and my Flolo friends will be there to assist you because our goal is “Keeping your future in motion”.

Motors for the Food Processing Industry

The Food Safety Modernization Act (FSMA) or “Fizzma” has been the law of the land since 2011. The primary purpose behind FIZZMA is to prevent food-borne illness such as salmonella and listeria before they occur. Prevention is the key – do it right the first time!In every food processing industry there is a myriad of electric motors used for many purposes. It is, therefore necessary to determine which motors can and should be used in which areas.

There are three zones in a food processing plant. Zone 3 is known as the non-food zone or dry zone. General purpose open drip proof or totally enclosed motors will work nicely in these dry zones.

Zone 2 is known as the “splash” zone. This zone generally has no direct contact with food, however, liquids from processing or cleaning may splash on the motors. Motors for Zone 2 locations should be rated IP55 or better and typical features include a white epoxy paint, neoprene gaskets, sealed bearings, shaft seals, stainless steel hardware and removable drain plugs.

The most critical area of a food processing plant is Zone 1, known as the High Hygiene area. Motors in this area should be rated IP69K capable of handling high pressure hot water or steam rinse. Typical features include all stainless parts, O-ring seals, sealed bearings, shaft seals, removable drain plugs and a laser marked nameplate.
Baldor Food Safe Smooth Finish Comparison
However, not all stainless steel motors are made equal. Baldor Electric is one of the leaders when it comes to food safe stainless steel motors. As you can see in the photos above, poor grade cast surfaces can propagate areas for microorganism growth. The Baldor Food Safe motor on the right has a smooth surface finish with no crevices that can catch or collect debris.

This is further shown in the flanges pictured below. The one on the left shows a low grade finish but the Baldor flange on the right shows a smooth, Food Safe finish.
flange comparison
When specifying Food Safe Stainless Steel motors, not just for your food processing facility but also pharmaceuticals and any other process where washdown can occur, please contact your Flolo sales representative to help you make the right selection and assist in preventing food contamination.

It is also important to note that washdown capabilities extend beyond motors to gear reducers and gearmotors as well as drives and many other products.

Call FLOLO today at 630-595-1010 and let us help you select the right products for washdown applications.
