Variable frequency drives (VFDs) are devices that regulate the operation of a motor by adjusting the frequency and voltage levels of the electrical input. They are commonly used in various electromechanical systems, from home appliances to industrial equipment. Like other electrical and electronic components, VFDs need proper and regular maintenance to ensure consistent and reliable ..read more

Rotors are essential components in electric motor operation. Keeping them properly balanced by addressing any issues in electromechanical systems helps ensure motor longevity and optimal performance. Learn more about why rotor balancing is important, how electrical and mechanical conditions play into a rotor’s alignment, and how preventative and predictive rotor maintenance can help you protect ..read more

Bearings are a critical element of electric motors. They facilitate even load handling, reduce friction, provide shaft support, and enhance the reliability and longevity of rotating components. However, without proper installation, operation, and maintenance, bearings can become damaged or fail. Here, we’ll go over some of the most common causes of bearing failure and how ..read more

Almost any industrial activity depends on an electric motor. When repair vs. replace considerations arise, the choice can result in thousands of dollars saved or lost. This is partly due to the direct repair/replacement costs but also as a result of downtime that grinds operations to a halt. Making the right call between electric motor ..read more

The National Electrical Manufacturers Association, or NEMA, is a trade association that sets industry standards for a range of electrical components, equipment, and medical technologies, including electrical motors. When motors are larger than the frame sizes outlined by NEMA, they are referred to as Above-NEMA, or A-NEMA, motors. In this blog, we’ll provide an overview ..read more

Using a hydraulic turbine, hydroelectric generators convert the mechanical energy of flowing water into electricity. Hydroelectric generators are connected to the turbine via a salient pole rotor. Generator rotors have field poles, which are multi-layered electromagnetic steel laminations surrounded by loops of wire arranged on the perimeter of the rotor. The number of field poles ..read more

While the transportation industry heavily relies on combustion motors, there has been a recent shift in focus to electric-powered vehicles. From cars and trucks to trains and locomotives to ships and ferries and not to forget mining equipment and buses, nearly every mode of travel can utilize electric motors for power. By converting electrical energy ..read more

Industrial electric motor systems have become more complicated, so when malfunctions occur, it is not always easy to identify the cause. Motor failure may be caused by mechanical or electrical problems, especially if the motor is improperly sized, installed, or maintained. Understanding the most common causes of motor failure can help you prioritize preventative maintenance ..read more

Hydroelectric power, the single greatest source of renewable energy around the world, is derived from moving water through the use of dams and hydroelectric power plants. Since no fuel is burned to create hydroelectric energy, it does not produce greenhouse gas emissions like more traditional fossil fuel power plants. The cost of running a hydroelectric ..read more

The oil and gas industry consists of onshore and offshore drilling operations, which rely on drilling rig equipment to extract oil and natural gas from reservoirs. Drill rig equipment often use electric motors as their power source, and these motors must be able to withstand vibration, extreme temperatures, consistent impacts, corrosive environments, and other harsh ..read more
