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.

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL
Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.

Festo Didactic at the Forefront of Developing Canada’s Future Work Force
With Canadian manufacturing suffering from a growing labour shortage, the participation of industry in skills development is emerging as a vital component in hiring and retention.
The needs are stark: The Canadian Exporters and Manufacturers Association says almost 40% of its members have jobs they can’t fill. Five years from now, 60% expect to be short-staffed, especially when it comes to skilled trades. Statistics Canada forecasts the country’s labour force growth rate will remain below 0.2% for the rest of the decade, below replacement levels.
This growing shortage is affecting companies of all sizes. Already, some manufacturers acknowledge losing out on contracts because they can’t find the manpower to fulfill them.
In reality, the challenge is two-fold: to replenish and expand the workforce to help close the gap between the number of job seekers and vacancies through 2030 when the last baby boomers reach age 65, and ensure workers get opportunities throughout their careers to upgrade or add to their skillset as current technologies evolve and new ones emerge. Festo, through Festo Didactic, one of the world leading provider of equipment and solutions for technical education, intends to help Canada meet this challenge on both fronts. In essence, the approach Festo has always taken is that the learning never stops.

New Emerson Valves Deliver Proportional Flow Control Performance in Exacting Applications
Emerson recently introduced the ASCO™ Series 209 proportional flow control valves, which offer the highest standards of precision, pressure ratings, flow characteristics and energy efficiency available in a purpose-built, compact architecture. With this combination of size and performance, Series 209 valves allow users to precisely regulate the flow of fluid in a wide range of devices that require exacting performance, like those found in the medical equipment, food and beverage, and heating, ventilation and air conditioning (HVAC) industries.
Accuracy, response time and repeatability are critical in high-precision flow control applications, such as controlling tool speed in dental chairs, the flow of steam in coffee makers, water flow in cooling systems and hydrogen flow in fuel cells. Series 209 valves have low hysteresis (less than or equal to 5%), excellent repeatability (less than or equal to 1%) and high sensitivity (less than or equal to 0.2%) that contribute to their precision.
