Electric Motor Repair vs. Replace – Costs, Benefits

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 […]

Motor Bearing Failure 101 – Types & Causes

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 […]

What Are Non-NEMA Motors?

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 […]

Mining Industry

Electric motors and generators are vital to the mining industry, allowing equipment such as mills, crushers, hoists, pumps, and haulers to operate. Tools and machinery for this work must be durable and reliable to enable seamless production in even the harshest of environmental conditions. When motors or generators do fail, this can cause significant interruptions […]

How the Aggregate Industry Utilizes Electric Generators & Motors

The aggregate industry in Canada and The United States is responsible for mining, grinding, and selling billions of metric tons of sand, crushed rock, and gravel every year. Aggregate is commonly used in the construction industry, where it is a primary component for applications such as asphalt, concrete, and road building materials. Aggregate is all […]

How the Oil & Gas Drilling Industry Uses Electric Generators & Motors

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 […]

6 Reasons Why Wind Power Turbine Maintenance is so Crucial

Wind power has proven itself a valuable player in the renewable energy market and currently stands as the fastest-growing renewable energy source in North America. Wind turbine generators drive the wind energy industry and have long-term investment potential in a fast-growing market. Wind turbine generators convert wind energy into electrical energy at a minimal cost […]

Common Causes of Electric Motor Failure

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 […]

AC vs. DC Motors: What’s the Difference?

Electrical motors are machines designed to convert electrical energy into mechanical energy. While they are available in numerous variations, they can be categorized into two main classifications: AC motors and DC motors. Both AC motors and DC motors have the same function; that is, to convert electrical energy to mechanical energy. However, when choosing a […]

Motor Rewinding 101: How You Can Benefit

Like all pieces of machinery, equipment motors are subject to wear and tear with the passage of time. If you find that the motor in your equipment is starting to operate inefficiently, that is typically an indicator that the deterioration process has begun. If your motor fails, or deteriorates to the point of impending failure, […]

5 Motor Testing Methods You should Be Implementing

To have an efficient electric motor running means more than just adequate performance; energy efficiency, operating cost, life span, and system reliability are all interconnected with overall motor health. To keep these variables in check, regular motor testing and monitoring are critical. Even basic diagnostic testing can allow for major cost and time savings, reducing […]

Is It Time for an Electric Motor Replacement?

Fix it, or replace it? When dealing with critical elevator components such as electric motors, it’s important to weigh the options carefully, taking into account all unique application requirements.
