3 Cost-Saving Advantages of Hydraulic Rope Equalizers

1 Comment

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

Leave a Comment

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powered by some type of geared traction machine, but this technology is now widely considered cost-prohibitive and outdated. […]


Fundamental Processes & Tools Used for Elevator Brake Adjustment

Leave a Comment

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?

Leave a Comment

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

Leave a Comment

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?

Leave a Comment

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

Leave a Comment

To measure the health of an electric motor, several key factors must be considered, including performance, energy use, operating costs, equipment durability, and overall system reliability. These are all integral components of motor health, which depends on regular monitoring and diagnostic testing. When evaluating the health of a motor, the following aspects should be carefully […]


Combatting Shaft Voltage & Bearing Current in Electric Motors

Leave a Comment

Variable frequency drives (VFDs) have changed the way we use electric motors and electric motor-driven equipment. With the ability to match demand loads and increase operating efficiency and output, these versatile tools allow for reduced electricity use as well as reduced costs. However, electrical noise — such as the shaft voltages and bearing currents that […]

Modernizing DC Gearless Elevator Motors Can Reduce Operation Expenses by 50%

Leave a Comment

In the majority of buildings constructed prior to 2000, elevators are operated by DC gearless motors. When problems arise, the first step is typically to replace the motor, but this can be a costly, complex procedure — and is usually unnecessary. Even after several decades of use, DC-powered elevator motors can still provide optimal service […]


How to Avoid Motor Shaft Voltage & Bearing Current Damage

Leave a Comment

In recent years, variable frequency drives (VFDs) — motor controllers that drive electric motors by varying the supplied frequency and voltage — have become more and more popular thanks to their superior performance, high potential energy savings, and low operating costs. Despite these benefits, however, VFDs can also cause significant motor bearing damage in just […]
