What

is

Electric

Motor

Rewinding?

Why do you need Electric motor rewinding and Electric motor rebuilding services? Sometimes we will repair shorted, grounded, or damaged motor coils by rewinding them. You can provide us with your motor and when we are able to complete our DC motor rewinding service on your motor, we can return the rewound coil and reinstall it with a rebuilt armature or others so that your motor will run back the way it should.

When

Should

You

Rewind

an

Electric

Motor?

Even the most durable motors are susceptible to degradation over time. Here are signs that it might be time to rewind an electric motor:

1.

Evidence

of

Deterioration

It is one of the tell-tale signs that a motor needs to be rewound. Your company may see broken elements, burns, or contamination like rust or moisture.

If you observe signs of degradation, your company will want to determine if your motor’s laminations follow suit. If so, you may need to get a new motor. If this is not the case, fast-forwarding may be the right way to go.

2.

Diminished

Winding

Resistance

Your company may notice a poor winding resistance on a motor or a professional may measure it. An example would be a technician using the winding resistance test to verify whether defective coils in the motor are affecting performance.

To start assessing winding resistance, locate the motor’s nameplate or consult the motor’s manufacturer instructions that accompany the motor. One of these locations is going to indicate the motor's optimal winding resistance level. If the measured numbers are far from optimum, you probably need to rewind.

3.

Problems

Of

Insulation

Resistance

A motor in need of rewinding may sometimes exhibit motor issues related to insulation resistance, as the coils in the actual motor begin to short.

There are many reasons why, such as high-power surges, high vibration, and contamination that can cause shorting and low insulation resistance. A motor that requires rewinding can cause these problems. Low insulation resistance creates many problems, including lack of lubrication and damage to the engine components.

Is

It

Worth

It

to

Rewind

a

Motor?

In certain situations, motor replacement can be a more worthwhile option than motor rewinding. On one hand, doing so is far more costly than replacing the motor. As well as saving you money in the immediate term, rewiring means that you get to make the most of your current motor for that bit longer. On the other hand, the extra investment may be worth it, as it nets you a new engine with years of top performance.

Should

You

Rewind

a

Motor?

Rewinding is usually cheaper and greener as they reuse the core motor materials. Starting fresh with all-new materials to create a new motor comes with a vastly greater carbon footprint and general environmental hit.

But this rule of thumb becomes more complex when you factor in the fact that a new motor might offer cost savings and environmental savings through greater energy efficiency. So your company might need to crunch some numbers to decide the best solution for your operations and budget.

How do you differentiate between the two situations? If a motor is quite old, in general, a replacement may be of better value than REWINDING, as it will break down or need ARK REWINDING more often. Or an aging motor might be so badly damaged that rewinding it would not return it to useful service. But if the motor is relatively new, rewinding is a low-cost option for improving performance and prolonging a generator's useable life.

When

to

Rewind

Your company will likely want to rewind a motor if most of these conditions apply:

  • The motor is noticeably deteriorated, exhibiting signs of burns, component damage, rust, or moisture.
  • The laminations remain in good condition.
  • The winding resistance has decreased.
  • The motor is not much more than about a decade old.

When

to

Replace

On the other hand, your company may need to replace the motor if most of these conditions apply:

  • The magnetic core of the motor is in poor condition.
  • Bearing failure has occurred to the point of significantly damaging the armature and stator.
  • The motor has otherwise sustained extensive or irreparable damage.
  • The motor has previously undergone incorrect rewinding.
  • The motor is more than about a decade old.

Our

Motor

Rewinding

Process

There are many steps to electric motor rewinding services we follow when providing services:

  • Record relevant data: We start by recording all the details to rewind your motor including the number of slots; turns of wire coils per slot, and pitch & wire gauge needed to wind coils to rewind the motor.
  • Cut out the bad windings: After we have all of the data recorded and inputted into our database it’s time to cut out the bad windings. Next, we clean out any excess varnish, insulation, or debris before re-winding the motor. A media blaster is another tool we use to safely clean things and remove debris and particles without harming the motor.
  • Steam clean the stator and give it an insulation paint: Next, we steam clean the stator and all other components of the motor to clean the dust. After all is clean, we coat the inner stator with insulation paint. Next, we place liner insulation in the stator slots, keeping the coils away from the core.
  • New coils and add to stator slots: Now it's time to make new coils. What type of winding head we will help the motor winding will depend on what type of motor it is. When winding, the person who winds checks the wire for defects. After creating the coils, the next step is to put them into the stator slots where applicable. Once the coils were positioned, we applied wedging to insulate and shield the coil.
  • Add lacing and varnish: The lacing will give some extra stability. Then we connect new motor leads and a final quality test. The dielectric test demonstrates the winding's integrity and quality. The motor is then heated in an oven to prepare dipping in varnish. The varnish holds the windings together and ensures the coils do not move. It also serves as a means to shield the windings from contamination.
  • Cure The Motor And Test: The final step is to cure the motor and then re-check the motor to ensure that everything is working properly.

This may sound like an extremely involved process, but for our trained repair technicians at Industrial EQ Diagnostics, it is practically automatic. Our technicians have wound literally hundreds of thousands of motors and it has become second nature. When you call Industrial EQ Diagnostics for your motor rewind and repair services, you can rest assured that you will end up with a quality motor that works almost brand new when it is all said and done.

Motors

Industrial EQ Diagnostics has been perfecting the process of rewinding AC and DC motors for exceptional repair and rebuilding.

A well-designed and properly performed motor rewind will have no efficiency degradation on electric motors, but you will see increases in power density, reliability, and overall efficiency as a result of the cutting-edge equipment and practices employed by your Industrial EQ Diagnostics certified technician.

Perhaps some other upgrades have crossed your mind during your rebuild and motor rewind, like the latest resins and insulating tapes, which will improve overall thermal dissipation, particularly if you are working with an older machine.

As a qualified service provider, we guarantee the rewound motor is returned to OEM standards and efficiency expectations. So the complete analysis is first towards a fantastic rewinding service for electric motors, to step back and check if the motor has got any fault that the in submitting process he or she did not realize.

If we find something, we’ll immediately reach out to you with an updated quote and details of our concern. We need your approval for each and every work in order to ensure both parties agree on the final amount.

Motor rewinding is highly standardized but we follow very strict guidelines to ensure speed and fast service without interference to core integrity. Here are the key components of our process:

  • Windings are removed carefully leaving the core's integrity and strength intact.
  • A computerized machine rewinds coils, preserving both consistency and precision.
  • We need things like copper and insulation from rewind materials.
  • Then, the windings are subjected to electronic testing.
  • The rewind is finalized by passing stators and armatures through varnish machines.
