What Factors Should You Think About Before Buying a New Industrial Pump?

Buying a new industrial pump is a huge investment, and it is important to do your homework before putting money down on a new pump. Here are some factors you should think about before making a purchase: Flow Rate This determines how fast a pump can pump a specific amount of liquid (gallon or liter) per minute. This is the most basic measurement of the effectiveness of the pump. Inlet Size The inlet size determines how fast a liquid can be sucked in and displaced. The bigger the inlet, the faster liquid can be processed through the pump. Composition of the Liquid to be Pumped Most ind

4 Little-Known Factors That Impact the Quality of Your Electric Motor Rewind

A superior electric motor rewinding service can make your existing motor run as good as–and sometimes even better than–new. But superior results depend on several factors that you might not have considered when seeking out an electric motor rewinding shop. Here are some of the things you should think about when selecting a service provider. Where the Motor Rewind is Performed An electric motor rewind is a delicate process, and removing the dirt, old insulation and grime accumulated after years of use within a motor is a difficult dirty practice (in most cases). These particles can co

4 Factors to Consider When Selecting Electric Motor Bearings

Motor bearings are a critical component of any electric motor, designed to consistently transfer loads from the shaft to the motor and support the rotor. The failure of these bearings typically result in expensive electric motor repairs. Here are some factors you should consider when selecting the best electric motor bearings: Speed The speed of the shaft directly impacts decisions you need to make about selecting the right kind of electric motor bearing. Some of the factors that need to be considered include: Lubricant used Size of the bearing Insulated or uninsulated? Cag

7 Field Services Every Excellent Electric Motor Repair Shop Should Deliver

There are many electric motor repair shops out there, but how do you know which one is right for you? One method you can use to compare them is to look at the “in the field” services that they provide. Here are seven field services every excellent electric motor repair shop should deliver. Availability of Service – 24/7/365 Electric motors never seem to break down during normal, 9 to 5, Monday through Friday business hours. They break down at night, on weekends and over holidays. That is the reality of working with electric motors. They can break down at any time. And you need to h

What Situations Are Good for Using a Variable Frequency Drive?

In general, Variable Frequency Drives (VFDs) are good for reducing the wear and tear of mechanical parts in large industrial electric motors because they “smooth out” the electrical current by eliminating power spikes. VFDs also reduce the impact of brown outs and other electrical problems associated with the use of large electric motors in the industrial setting. These issues most commonly appear when the motor starts up, since electric motors typically require a lot of power at the start, but they can also occur in any situation where the load on the motor varies, or needs to star

Repair or Replace? – 6 Things to Think About When Servicing an Electric Motor

Repair or replace an existing electric motor? This is the dilemma that all companies that use them faces from time to time. Both replacing and repairing electric motors is expensive, so how do you determine the best course of action when you find your electric motor out of operation? There are several factors you need to consider before making a decision and you need to gather the information about all of them before making the best choice for your operation. Was There a Bearing Failure? Bearing failures are a common problem with electric motors, and if a bearing failure occurs, it cause

4 Qualities of an Excellent Electric Motor Rewinding Shop

There are a lot of shops out there who perform electric motor rewinding service, but how do you select the best one for the job? Here are four qualities you should look for in an excellent electric motor rewinding shop: Provides Thorough Testing Services for the Electric Motor One of the most important aspects of an exceptional electric motor rewind service provider is the ability to determine if a rewind is needed in the first place. Performing tests such as surge and hipot testing and core tests are helpful in determining if a motor will benefit from rewinding in the first place and/or

3 Features of NEMA Electrical Motors

We’ve already covered what a NEMA electric motor is in another blog post. NEMA stands for the National Electrical Manufacturers Association and is an organization that was created as part of the Energy Independence and Security Act of 2007 (EISA). The purpose of this organization is to improve motor efficiency in order to reduce the energy and operating costs for industrial, commercial and institutional buildings and, as a result, reduce the amount of electricity consumed by electric motors and reduce pollution. One of NEMA’s goals is make it easier for companies to manufacture elec

What is an Electric Motor Power Quality Study?

In the past, if you needed to evaluate the performance of your electric motor you needed to take it offline, where you could test the motor in a motor test bed. The problem with this method of electric motor testing is that it was not an accurate reflection of the motor’s performance in the facility where it operated. A motor test bed tests the electric motor by simulating the best possible conditions. Why Is an Electric Motor Power Quality Study Important? Electric motors are staples in industrial companies all over the world, and some studies have shown that they can consume up to 70

What to Look for in an Overhead Traveling Bridge Crane Inspection—Part 2

Last month in Part 1 of What to Look for in an Overhead Traveling Bridge Crane Inspection, we covered what to look for in the hook and thrust opening, hoist rope, rope drum, limit switch and brakes. Here are some other points of inspection during a traveling bridge overhead crane inspection: Trolley Motor and Coupling The trolley motor powers the hoisting mechanism traveling on the bridge rails and needs to be inspected monthly for any excessive wear and tear, leaks or cracks. The trolley coupling also needs to be inspected monthly for the same–excessive wear and tear, cracks, etc. It al
