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, […]

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 […]

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 […]

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 […]

3 Elevator Components that Benefit from Implementing a Hydraulic Rope Equalizer

Hydraulic rope equalizers provide real-time rope tension adjustments across elevators and other lift systems while in operation. Uneven rope tensions ultimately add additional stress to vital components, negatively affecting the system’s operational lifespan and degrading performance. As safety and maintenance are paramount, elevator installers are now considering increasing the use of hydraulic rope equalizers. While […]

3 Cost-Saving Advantages of Hydraulic Rope Equalizers

Equal rope tension is critical to an elevator’s operations. Elevators used in high rise and high speed applications are particularly sensitive to uneven rope tensions, suffering from unnecessary wear, excessive vibrations, and unwelcome noise as a result. The rope tensioning process is complex. In most static systems, the balance must be checked by an installer […]

Renown Electric Transition from Geared to Gearless Machines for Your Elevator

3 Reasons to Transition from Geared to Gearless Machines for Your Elevator

Click to Expand These days, the world’s cities are filled with high-rise apartment buildings and soaring office spaces that require elevators to travel faster than ever before. Many of these buildings – especially older ones – may still use elevators powered by some type of geared traction machine, but this technology is now widely considered […]

Fundamental Processes & Tools Used for Elevator Brake Adjustment

Brakes are an essential component of an elevator’s safety system. Most modern passenger elevators contain a redundant system of at least two to three types of brakes. In addition to being responsible for stopping a car during emergency and holding the elevator in place during normal operation, brakes must also ensure smooth, quiet, and uninterrupted […]

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. Choosing Motor Replacement Over Repair Electric motors are used to move elevator cars up and down, with heavy-duty metal cables and pulleys running between the cars and […]

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 — […]

The Basics of Motor Testing

To measure the health of an electric motor, engineers must consider several key factors, including performance, energy use, operating costs, equipment durability, and overall system reliability.
