What Is Rotor Balancing? A Quick Guide

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 […]

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 […]

Rewinding Services

The Importance of Generator Repair and Maintenance for the Hydroelectric Sector

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 […]

Electric motor maintenance for transportation sector

The Integral Role of Electric Motor Maintenance for The Transportation Sector

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 […]

Why Electric Motor Repair is So Important for the Mining Industry

In the mining and mineral processing industry and almost every other industrial operation, electric motors are at the heart of the operation and present in almost every aspect of industrial works. Electric motors drive large equipment like crushers, mills, and driving hoists, and even small reagent dosing pumps. They are an essential part of mining […]

Top Benefits of Using Laser Alignment for Motor Repairs

The alignment of a motor’s structural and mechanical elements influences its performance and longevity. Using laser alignment technology to facilitate motor repair and maintenance operations allows companies to ensure that parts are properly aligned and make adjustments as necessary. Laser alignment uses laser instruments, such as transmitters and receivers, to measure the alignment (or […]

What’s the Difference Between Static & Dynamic Balancing

Rotating parts in machines should be free of vibration to ensure their smooth operation and long service life. Reducing the vibration in your machinery relies on a number of factors, like a smooth rotating shaft, good bearing condition, and proper lubrication, but one of the most important ways to guarantee vibration-free operation is through symmetrical […]

Are You Optimizing Your Sheave Regrooving & Maintenance Processes?

Over an elevator’s life span, its sheaves will typically require regrooving. Due to increasing demands and traffic, wear on equipment is higher, upping elevator maintenance requirements. Sheave regrooving ensures elevator cables have sufficient grip on the sheave to accommodate the weight of the lift and its occupants for efficient operation. Proper Sheave Care Renown Electric’s […]

The Importance of Oil Analysis for Motor Systems

Oil analyses are performed on used engine oil to determine the specific properties and characteristics of the oil. In this way, operators can better detect possible wear or contamination occurring in the engine as well as any outside contaminants that may enter the system from breather ports or pool oil replenishment practices. The Benefits of […]

Why Does My Motor Pass a Megger Test and Still Not Work?

Electric motors consist of multiple individual moving parts that work together to create rotary or linear motion. Because motors are so complex — and made up of so many different components — pinpointing the cause of issues can be challenging. To identify what’s causing the problem, operators may need to test each individual part — […]

Preparing for Your Scheduled Shutdown? 7 Things to Check

Facility equipment — especially industrial motors — naturally wear down throughout operation, sometimes to the point of failure. In order to avoid costly unplanned downtime, plant managers should administer scheduled shutdowns at least once a year. Annual motor maintenance not only lengthens equipment life — it also decreases energy consumption. These planned shutdowns allow for […]
