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 […]

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 […]

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 […]

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 — […]

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. 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 […]
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 […]

Clean wind energy, one of the world’s fastest growing sources of new electricity, is seeing major gains in Canada; in 2016 alone, 702 megawatts (MW) of new capacity was added across the country. Ontario, in particular, is leading the way, having completed 79 new installations comprised of 2,302 wind turbines. Below, we’ll take look at […]
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 […]
