Based out of Toronto, David Willick, VP & Regional Segment Leader for Mining, Metals and Minerals, Schneider Electric, is a mining industry veteran.
The ability to size servo motors correctly is imperative for motion-controlled applications, and it can be much more involved than sizing AC induction motors. Acceleration, deceleration, and running torque must still be taken into account, but the servo’s ability to dynamically control the load’s speed and position is also important.
Many organizations are at risk of continued interruption to operations due to coronavirus and possible future pandemics.
When selecting a motor, it is important to consider the required duty cycle to ensure the motor can meet the needs of the application. This blog post and the accompanying light board video will provide a basic introduction to motor duty cycles and a few of the most common types of duty cycles.
Energy overload situations can cause braking resistor failure, but is easily prevented with the right equipment and system design. In this article we’ll explain the cause of overload conditions and present three methods that will help you address this common problem. After all, you want to protect your VFD and related equipment in order to prevent unhappy customers and co-workers that experience a system failure.
The benefits related to energy savings when using variable frequency drives (VFDs) in pipeline pump and compressor stations are well established. Drives provide the precise control needed for increasing or decreasing flow along a pipeline. The result is greater efficiency and energy savings than an across-the-line motor starter that requires the use of control valves to manage flow.
SPCC, Southern Peru Copper Corporation, used Roxtec cable seals when extending the Toquepala copper ore mine on the Andes mountain range. It was far better than cable glands.
If the main power is lost to a VFD while the motor is under load, the DC bus of the VFD drops at an accelerated rate compared to no load conditions. When the DC bus reaches a low level, the VFD would shut down, disabling the output modulation and releasing the motor to coast to a stop. The motor coasting to a stop under the loss of main input power may not be of concern for many VFD applications.
When one major mining company underwent digital transformation, it achieved results that would be the envy of most mines. Production increased about 15%. Energy costs went down after ventilation demands were cut in half. And safety was enhanced with autonomous drills that moved workers away from potentially hazardous areas.
With the spring tradeshow season coming upon us, and discussions beginning to come up about the new innovations that will be showcased this year it is important to also slow down and think about the innovations that were unveiled last year. We are often so focused on what is coming that we don’t really take the time to consider the full impacts of what we only recently learned about.
Fitness trackers for people are a genuine success story: more than 40 million are already in use worldwide, helping individuals to stay healthy and improve their fitness. Monitoring and saving vital data like heartrate and blood pressure, the device tracks not only current fitness but also follows an individual’s fitness development over time.
Maintaining highly efficient operation is important in today’s industrial market. Moreover, users are searching for ways to not only make their systems operate efficiently, but also provide a financial benefit. The financial benefit is materialized in saving regenerative energy.
We live in a time where variable frequency drives (VFDs) are now the standard when it comes to motor control. As they’re being installed primarily in commercial and industrial buildings, both new and old applications are reaping the benefits these intelligent devices bring. But just like all electronics, VFDs do not last forever.
To date, food producers have so far often been sceptical about the use of connectors in sensitive areas. Given their profiles and footprints, they fear that interfaces will interrupt the smooth, easily washable surfaces needed for cleaning in areas close to the product.
Sawmills and lumber mills take freshly cut logs and process them into construction grade wood of all shapes and sizes. The process of turning a log into a usable piece of lumber has more or less stayed the same; the largest change to the manufacturing process is that it has become largely automated. In order to accomplish the advances in industrial automation, leading edge processors are incorporating variable frequency drives.
What is the best way to power a fan array in a critical operation? For those who may not know what a fan array is, a fan array is exactly what it sounds like – a series of smaller fans designed to carry the load once handled by a single larger fan.
