What Are Some Common Electric Motor Control Problems?

All in all, electric motors are some of the most reliable equipment around. They are used in almost every environment, including some very extreme environments. As a result, they can be damaged by getting contaminated by dirt, moisture, oil or grease. They can be installed incorrectly, mishandled, or even run in conditions that go beyond what they were built for. These situations can impact the motor control and cause many different types of problems which may require some troubleshooting. Loss of Phase Voltage One of the common problems encountered while diagnosing a motor for an electric m

A High-Level History of Overhead Cranes

Almost everyone has seen an overhead crane, either in person because they work for one of the many industries such as automotive manufacturing, steel production, loading and unloading of ships and trains, or any number of heavy industrial manufacturing plants; or in the movies or on TV. But what many people don’t know is that the overhead crane has been around for over 175 years. The first overhead cranes were steam powered and invented by the German company, Ludwig Stuckenholz, in the 1830’s and were mass produced in the 1840’s. But the first electric overhead crane did not appea

Different Types of Overhead Cranes–Part 2

Overhead cranes are a fixture in many industrial and manufacturing environments, and typically they are customized to meet the company’s specific needs. Back in October, we started a new blog series about the different types of overhead cranes that Tekwell Services provides inspections and repairs for. If you missed part 1 of this series check out Different Types of Overhead Cranes– Part 1. Jib Cranes These cranes do not have a track or runway like single and double girder bridge cranes. They appear as two girders attached at a 90-degree angle like a straight branch jutting out from a t

Different Types of Overhead Cranes

At Tekwell Services, we see a lot of different types of cranes. We do a lot of overhead crane inspections and repairs, so we are in a perfect position to give you an overview of them. There are many types of overhead cranes and these have been customized in many different ways, so this blog series is going to define the major types of overhead cranes we encounter during our inspections and repairs. Definition of an Overhead Crane First of all, overhead cranes are also known as bridge cranes and although they are most commonly used in industrial manufacturing such as automobile manufacturing,

6 Benefits of Dynamic Field Balancing

We’ve discussed the causes of unbalance that creates the need for dynamic field balancing services in another blog post, but we have not really covered the tangible benefits of equipment that has received this service. The first thing to keep in mind is unbalance in any rotating machinery, but particularly in an electric motor, is the most common cause of failure. This can even happen if repairs have been made, such as parts being replaced that became defective due to imbalance issues. Imbalance issues create excess vibration and if you fail to address the root cause of that vibration with

Benefits of Using a Burn Off Oven for Electric Motor Repair

Rebuilding an electric motor can be a difficult, labor intensive process. The first step to rebuild an electric motor is cleaning it thoroughly. You need to remove all dirt, grease, paint, insulation, varnish and epoxy that encases the motor. The copper wire coil must be clean and exposed. There are several ways to do this. The most common being doing it by hand by scraping, sanding and removing the debris using chemical solvents and strippers. This can damage the parts. Another–less damaging–method, is to use an ultrasonic cleaner. This is less invasive and often does the job quite wel

What is an Automatic Capacitor Reformer and How Does It Benefit Electric Motor Repair?

An automatic capacitor reformer is an essential tool for any industrial electric motor asset management program. It allows a user to determine how much calculated capacitance of an electrolytic capacitor bank has remaining. The reason that this is important is that as an electrolytic capacitor ages, it loses its maximum capacitance and drops way below the original specs. As a result, it is important to know exactly how much capacitance remains in a capacitor to determine if it needs to be replaced to avoid failure when the power is needed or avoid replacing capacitors before it is absolutely n

The Impact of Lubrication and Vibration on Electric Motor Bearings

The proper care and operation of electric motors depend on how well you protect your motor bearings from poor lubrication and excess vibration. Here are a few of the ways you can keep your bearings in tip top shape and prevent unplanned downtime due to bearing failure as a result of these two problems. Maintain Proper Lubrication for Your Bearings Lack of lubrication is the number one cause for bearing damage and failure. This can be caused by a number of different reasons. The first being that you failed to provide adequate lubrication in the first place, used the wrong kind of lubricant
