Common Causes of Balancing Issues – Requiring Dynamic Balancing

When electrical motors are out of balance, bad things happen. Unbalance happens when the rotor mass is not at the center of rotation, and this can lead to problems such as inefficient operation, unplanned downtime, and equipment breakdown. But what are some of the factors that cause balancing issues? Wear & Tear Daily operation, especially for electric motors with a lot of use, leads to wear and tear. And wear is never neat and even. It always is rough and uneven, which leads to imbalance. Corrosion & Dirt Build Up If a component attached to the electric motor gets corroded or

The History of Electric Motors – Part 1

The electric motor has been around for a long time. A lot longer than many people might be aware of, with many discoveries leading to other breakthroughs. Early Beginnings of Electric Motors It started with electrostatic devices that used a sulfur ball and a glass cylinder to create friction. A Scottish Benedictine Monk named Andrew Gordon and Benjamin Franklin used this method to create a “frictional machine” in the 1740’s. And not a lot of progress was made for almost a century until Hans Christian Ørsted, a Danish physicist and chemist, discovered the relationship between elect

The Benefits of Testing an Industrial Pump Repair with a Closed Loop Test Tank

The success of repairing industrial pumps offsite is sometimes a guessing game. There rarely is a way to test the effectiveness of your pump repair other than by installing it back into the system. If the pump isn’t fixed right the first time, you now have a bigger problem on your hands. So how do you make sure that an industrial submersible pump repair is done right? Tekwell Services has a solution. What is a Closed-Loop Water Tank? A closed-loop water tank is a huge water tank that is 6’ by 6’ by 8’ and holds over 2000 gallons that Tekwell’s engineers constructed to measure an in

What Are the Differences Between Yaskawa AC Electric Motors?

Yaskawa has a reputation for building solid AC motors, but they have several different types available on the market right now. There are many similarities, such as they all have a 3-year warranty, all are three-phase motors, all use ball bearings (except for a few notable differences), and all are UL Recognized, CSA Certified. But what are some of the differences? MicroMAX The MicroMAX inverter duty motors range from 1/8 to 10 HP at 1800RPM and appear in two different enclosures, the TEFC –for 20:1 constant torque and the TENV–for 1000:1 constant torque. This product line is desig

How Does an Ultrasonic Cleaner Work?

Ultrasonic cleaners have been around since the 1950s, and smaller versions have appeared in home appliances since 1970, but how does an industrial ultrasonic cleaner work? All types of ultrasonic cleaners use cavitation bubbles—bubbles created by rapid changes of pressure in a liquid–to clean parts with lots of crevices and complex shapes within them. Why Ultrasonic Cleaners Are Popular Ultrasonic cleaners are popular for a couple of reasons: They are less destructive than other methods for cleaning electric motor parts. Pumps, sprayers, and agitators may be damaging to del

7 Often Overlooked Factors to Consider Before Purchasing a New Electric Motor

There are many factors to consider before purchasing a new electric motor. Typically, you look at things such as voltage, speed, torque, and operating costs, but what are some of the lesser-known factors to take into consideration before purchasing a new electric motor? 1 – Power Needed One of the most important factors to consider is the amount of power needed to run the applications this motor has been selected for. Get a motor that is too small, it gets overworked and the stress this creates decreases the motor lifespan overall. On the flip-side, if you buy a motor that is much too big
