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

Comments Off on 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

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

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

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

Comments Off on How to Avoid Motor Shaft Voltage & Bearing Current Damage

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 […]
