• 4 Tips for Mitigating Risk in Defense Programs

    Juni 26, 2013, by Mike Crowe

    Quality, Delivery and Cost (QD&C). These are the factors most used to determine the value of a supplier. They are also the aspects of performance that we can most easily calculate, compare and analyze. A green supplier scorecard that shows high OTD (on-time-delivery) and low DPM (defects per million), along with competitive pricing is the dream of both Buyer and Supply Chain Manager alike.

    In the high-stakes market of Military Defense products, however, this is not quite enough. With programs taking years to develop and often requiring decades of production and support there is another critical factor in evaluating a critical supplier. A company’s ability to minimize risk over the life of the program is of epic importance.

  • Whatever Happened to the Pacific Scientific Brand?

    All those permanent magnet DC motors, synchronous motors, servo motors, servo drives, stepper drives, oh yeah, and remember the great stepper motors they offered? The one stepper motor was a weird shape. It was octagonal where others are square or round. Hard to forget that one!


  • New Food Safety Regulations: Preventative Controls Review Extended

    September 18, 2013, by Andy Hansbrough, P.E.

    Consumers expect safe food. The Feds expect a safe food supply chain-farm, processing, packaging, and distribution. As we all work to consistently meet consumer food safety expectations, the need to prevent and control food adulteration and/or contamination is present in every step of the supply chain. Our modern and globally expanding food and beverage processing and packaging industries have made and continue to make great strides in improving food safety by improving preventive, control, cleaning and sanitation methods.

  • Food Recall Hits Close to Home

    März 18, 2014, by Emily Blanchard

    Normally my blogs are light hearted and meant to provide some thought provoking ideas in entertaining ways. Today's blog does not have that tone. On February 21st, a recall for a soft cheese was issued due to high amounts of Listeria monocytogenes. Virginia and Maryland have been investigating the products from the manufacturer, but the sad truth is there has been a death associated with this disease. Adding to the sadness is that the CDC is not reporting the age of the person who died, but nearly half of the reported sick were newborns.

  • 3 Key Reasons for NOT Taking Shortcuts for Motor Repairs

    Februar 02, 2015, by Paul Coughlin

    Brushless AC servo motors and stepper motors have long life spans, which are largely due to the lack of wearing components. Unlike brush type motors, other than the bearings, brushless AC servo motors and stepper motors have no wearing components. Additionally you do not have conductive brush dust, which, as it collects on the commutator, may short the armature. The radial and axial loading requirements of step and servo motors are based upon the shafts of the motor, which are usually far less than what the bearings are designed to handle, which provides for a healthy motor life span. However, occasionally motors do need to be repaired. Either a feedback device goes bad, or some kind of electrical mishap may cause the drive to provide too much current, which may damage the winding, or it could be as simple as the bearing grease drying up.
