VSDs Reduce Risk
Using Variable Speed Drives to Reduce the Risk of Pump Cavitation
Cavitation can be a serious issue for industry. It causes damage to pumping systems, reducing their lifetime and requiring costly maintenance and replacement, while in the beverage and dairy industry it can impact the quality of products being pumped. This article outlines the causes of cavitation and explains how the latest variable speed drives (VSDs) offer an efficient and cost-effective method to prevent it.

Motor Considerations
Brushed vs. Brushless DC Motors - What’s the Difference?
In the world of motors, efficiency is king. Consumers are looking for not only efficiency in cost to operate but also in ability to get the task done quickly. When converting electricity into rotational motion via motors, a major contributing factor to efficiency is the type of motor, such as a DC motor, used to keep the momentum going. There are two major types of DC electric motors, brushed and brushless.

4 Reasons to Upgrade to Modern Motor Systems
Although modern motor technologies offer significant potential energy savings to business owners, the majority of motors currently in use are outdated and inefficient. In fact, a recent survey of the US market found that over 60% of industrial motors are over a decade old. Here are four reasons why it’s worth updating to more modern motor systems such as magnet-assisted synchronous reluctance...

HELUKABEL: Update - VFD Cable Design Requirements
The variable frequency drive (VFD) cable business has become a very large market for cable manufactures in the last 20 years. In the past, standard AC motors had the complexity of a squirrel cage motor – just get power and it would run. The first silicon controlled rectifier (SCR) was developed by Bell Labs/GE in 1958 to vary the speed of DC electric motors used in various applications.

A BRAVE New World for Bearings
Some ten billion bearings are manufactured each year and, given the harsh conditions to which they are often subjected, they are incredibly reliable. Indeed, approximately 90% of these bearings outlive the equipment to which they are fitted. Only 0.5% of bearings fail in service, but this still means that some 50 million are replaced due to damage or failure every year, and each of these failures...

Safety and Quality
What Are Acceptable Lockout/Tagout Locks?
When it comes to the possibility of someone accidentally restarting a piece of equipment that another employee is working on, the only device that is protecting the employee is their lockout lock. It’s imperative that employees understand how to properly use their locks and also know to never lend out their lock or key, to ensure exclusive control at all times. When employees understand safety...
