Factors to Consider Before Using a Motor Rewinding Service

One of the challenges of working with electric motors is determining what to do when the motor fails. Do you rewind the motor or replace it? Here are some things to consider when determining if using a motor rewinding service is right for your motor: How Old is the Motor? The age of the motor is a factor due to the standards established by the Energy Policy Act of 2005, and the Energy Independence and Security Act of 2007. These laws established new efficiency requirements for electric motors (as part of the overall program) and these motors are far more efficient and thus less expensive

Causes of Unbalance in Electric Motors

Unbalance is one of the major causes of electrical motor failures requiring often expensive repairs or replacement. One of the best ways to prevent this from happening is to perform dynamic field balancing services at the first sign of trouble. What are the Causes of Unbalance in Electrical Motors? In general, they are all caused by an uneven distribution of mass around an axis of rotation. This uneven distribution can be traced back to several different causes such as a buildup of dirt or grease on fans, normal wear-and-tear of moving parts, or corrosion within the bearings, rotor, or s

4 Benefits of Dynamic Balancing for Electric Motors

An unbalanced electric motor can cause many problems. The most significant of which being a catastrophic failure due to excess vibration that result in bearing failure, cracks, and other structural defects.  Here are just a few of the benefits of dynamic balancing. Minimizes Noise A well-balanced electric motor is a quiet electric motor. Noise is one of the first signs of a problem. Excess noise is the result of vibration and vibration, if left unattended, makes the problem worse. In addition, noise can annoy or cause fatigue in the operator or others at the workplace leading to lost pr

What is Hipot Testing?

Hipot (or high potential testing) is a non-destructive test that has many names: overvoltage testing, dielectric breakdown test, dielectric withstand test, or insulation resistance tests. All of these tests are designed to make sure that the insulation used in your electric motors are doing their jobs. If the insulation is defective or not performing as expected, the results can lead to power leakage or short circuits which may cause the motor to fail or damage it. Another huge danger of defective insulation is the risk of shock to anyone who comes in contact with that motor. A Hipot tes

4 Benefits of Using a Motor Rewinding Service

When your electric motor is not performing as expected, you often must make a critical decision about it: Rewind it or replace it. There are some instances where rewinding a motor simply is not a practical solution, but many times using a motor rewinding service is a better, lower cost, option. Here are the benefits of using a motor rewinding service: Saves money At less than half the cost of replacing an electrical motor, a motor rewind is an especially cost effective solution when considering large enclosed motors over 100hp. Saves time Most motor rewind jobs take less than x # of hou

4 Benefits of Implementing an Industrial Electric Motor Asset Management Program

A well run industrial electric motor asset management program allows a company to get the most out of its existing electrical motors, as well as making good decisions on whether to repair or replace existing electric motors. Reduce Energy Costs When your existing industrial electric motors are running at peak efficiency, you are saving money on energy costs. And since this is estimated to be 95% of an electrical motor’s operating cost over a lifetime, this savings can be huge. With this in mind, a decision may need to be made about replacing an older, less efficient electric motor, with a

Best Practices for Industrial Electric Motor Asset Management

An industrial electric motor asset management program helps assure that all of your critical electric motors are running at peak efficiency as well as remaining cost effective for your business. How do you set up an industrial asset management program? Read on. Start a Program Get buy in from management by showing the benefits of an electric motor asset management program, and appoint someone to be in charge of it. Inspect and Test Existing Electric Motors This is one of the most important actions you can take for your industrial electric motor asset management program. Get your motors

What is a NEMA Electric Motor?

NEMA stands for the National Electrical Manufacturers Association. As part of the Energy Independence and Security Act of 2007 (EISA), this organization helped create the provisions for this law surrounding the improvement of motor efficiency in order to reduce the energy and operating costs for industrial, commercial and institutional buildings, reduce electric consumption for electrical motors and reducing pollution as a result, and help identify higher efficiency electric motors for customers. NEMA Premium Motors Reduce Carbon Emissions NEMA also established a NEMA Premium energy efficien

Benefits of an Electric Motor Circuit Analysis

An electric motor circuit analysis is a great way to get electric motor testing done quickly, but what are some of the other benefits of an electric motor circuit analysis? Saves Money An electric motor circuit analysis saves money simply by identifying problems or indicators of future problems early in the process, before they grow into expensive repairs or a critical failure resulting in downtime. Identifies Potential Problems Onsite Most electric motor circuit analysis tools and applications are portable, allowing the operator to perform the analysis at a customer site. This allows a qu

Across the United States, countless electric motors whirl, pumps labor and cutting-edge controls keep it all going. Most people have no idea how important these motors are, though, and they don’t know about companies like Tekwell Services LLC, a motor repair and maintenance company that works behind the scenes to keep motors, pumps, gearboxes and fans—anything that rotates—functioning properly.[click here to read feature article in US Business Executive magazine]
