Solution Spotlight: Re-Introduced: A Winning Motor Repair Process

dreisilker_motor-safeCheck out this energy-saving alternative to burnout methods.

Dreisilker Electric Motors is re-introducing its trademark Motor-Safe Repair System for rewinding electric motors as an alternative to other destructive methods using burnout ovens. The company points out that this process results in finished motors that are more efficient, reliable and longer-lived than those subjected to burnout-oven rewinding methods.

How it works
Using the Motor-Safe process, a technician carefully removes the original windings using a controlled “warming” method and hydraulic device. This technique pulls the softened windings from the stator without damaging the stator and thus avoids the extreme, uneven temperatures of burnout ovens that distort the core and laminations. In addition to maintaining the structural integrity of the motor frame and components, the Motor-Safe process allows for a faster turnaround—typically a 1- to 2-hour process, compared to 8 to 10 hours using burnout ovens and other destructive stripping methods.

The vast majority of motor repair shops use burnout ovens to remove original windings by baking the motor to exceed 680 F. Those types of high, uneven temperatures compromise the integrity of the motor core with frame damage and iron distortion. High heat also damages the insulation of motor laminations, causing circulating currents, hot spots and uneven amperage draw. A motor coming out of such a process runs hotter, is less efficient and has a shortened half-life.

A nationwide reach
Dreisilker Electric Motors, Inc. is a leading provider of commercial and industrial motors, drives, controls and repair and field service expertise to a wide range of industries, including: machine tools, utilities, municipalities, water reclamation, heating-ventilation-air-conditioning (HVAC) and material processors.

Vacuums For Lifting Heavy & Lightweight Objects

EXAIR’s new Adjustable E-Vac® is a series of low-cost, compressed-air-powered vacuum generators in which vacuum and flow rates can be easily adjusted to suit the application requirements. Engineered for high efficiency, these products minimize compressed air use by allowing it to be tuned to the application. With a simple turn of the unit, the vacuum and flow levels can be changed to overcome porosity and increase or decrease the lifting power. The straight-through, single-stage aluminum construction requires no vacuum filter and simply passes contaminants from dirty environments through the unit so there is no clogging or loss of suction. According to EXAIR, these units are ideal for a wide variety of “pick and place,” box-opening, clamping, lifting, chucking and surface-mounting applications. Maintenance-free, they have no moving parts to wear out.

Current Diversion Ring Protects VFD-Controlled Motors

inproseal_0709VFD-controlled motors inherently produce destructive shaft currents that must be redirected around the bearings. Otherwise, unmitigated electrical currents initiated by the VFD and induced by the motor shaft destroy the bearings. Inpro/Seal’s Current Diversion Ring (CDRTM, patent pending) safely diverts these currents and saves the motor bearings. Available through all major motor manufacturers around the world, as well as EASA repair facilities, the new device can be furnished either as a “press-in,” a “Clip-on,” a “split” configuration or an “MGS” design, which prevents contamination from entering the motor bearing enclosure while diverting destructive shaft currents.

Viewpoint: The Value Of Services During Tough Times

blake_moret

Blake Moret, Vice President and General Manager Customer Support & Maintenance, Rockwell Automation

Navigating waves of bad economic news is never easy, and no one is certain when the storm will let up. However, companies that view tough times as an opportunity to improve will eventually come out on top. Even with aggressive cost-cutting, there are many ways to optimize the performance of remaining workers and assets. Consider the following:

Parts: In a “cash is king” environment, deferring expenditures is always an option. When it comes to maintaining production equipment, allowing on-site spare parts to dwindle may be an outcome. However, before taking actions that further jeopardize the productivity of remaining assets, consider a vendor-managed parts repair and replenishment program. Such programs start with a detailed analysis of existing assets, and prescribe a formula for distributing stock of critical spares among manufacturer, distributor and user. This may actually free up cash. Consolidation of repair vendors can reduce transactional costs and relieve purchasing departments already stretched by prior cuts.

For example, when Pepsi Bottling Group became overwhelmed by the many sensors in its inventory, we set up a services agreement that included parts management. Today, Pepsi pays a fixed monthly cost for spare parts that are owned and managed by us—yet stocked on-site at Pepsi facilities. This lets Pepsi reduce up-front expenses, have immediate access to spares, reduce carrying costs and economically update its control technology. Also, parts don’t go out of warranty before they’re used.

Labor: Maintenance staffs everywhere are worn thin. With fewer hands to do the work, those who remain are often cast into new roles. Structured needs assessments provide the basis for customized training to build the skills workers need now. Access to sources of a contingent technical workforce can help bridge gaps when training is not enough. Finally, remote technical support offers a low-cost way to leverage the accumulated knowledge of equipment manufacturers.

Remote Support: Remote support encompasses a range of services, from self-help access to knowledge databases, to live support via phone and chat, to continuous Web-enabled process monitoring from a command center. Users tailor their desired approach, based on factors like number of sites and hours of coverage and the required degree of familiarity with specific applications.

CENTRIA, a leading supplier of architectural wall and roofing systems, knows the value of remote services firsthand. It has a services package with round-the-clock access to a team of specialists who have intimate knowledge of the company’s processes and control system components. Engineers at our command center continuously assess production status using proprietary software applications that compare real-time and historical process data to a predetermined optimal range. If a parameter deviates outside the range, we notify production personnel at CENTRIA—often before they realize there is a problem—and begin troubleshooting. We then collaborate with plant maintenance to execute corrections and restore normal operations.

Consulting: Manufacturers finding themselves in unfamiliar waters may need outside help to better define new challenges. Consulting services can prescribe steps to optimize availability, safety, performance and compliance of assets. Resulting recommendations will likely include a mix of the services previously described.

For the remainder of the recession and as the economy recovers, manufacturers will place strong emphasis on the value of collaborative partnerships. Suppliers should be able to help define the typical ROI from a comprehensive support program. They should take time up front to identify those KPIs with a proven impact on financial performance, then create a winning strategy for increasing operational efficiency without depleting scarce resources.

Motor Doc's Hot Topics: The Use And Misuse Of Standards In Sales And Marketing

In my work, I often ask companies about the standard(s) they follow. Most will cite IEEE, ASTM, EASA, IEC, UL, CSA, etc. Generally, the language and standard(s) are correct and the companies appear to be complying. Sometimes, however, they aren’t—either accidentally or, in enough cases to be annoying, deliberately.

What is the impact when a standard isn’t followed? For the buyer, the price of products/services can be lower than those from companies that perform to actual standards. Conversely, not following standards can result in a very costly product or service—something that may put people in danger, damage equipment, lead to lost production, expose the buyer’s organization to litigation and/or the denial of insurance coverage.

How do you avoid these problems? Remember this: any company that truly follows standards or certification processes will be proud of the fact. Compliance with standards is not just something to protect you, the buyer; it’s also a sales and marketing tool for the vendor. If you run into a supplier who objects to showing you its applicable standard(s) or certification(s)—or acts insulted because you’re asking—your next step should be to dig deeper. A legitimate company would be able to show either a referenced standard or certificate on the spot (or at least obtain it for you in short order). Company representatives also should be familiar with the parts of the standard or certification that involve their product or service.

Industry standards and certifications reflect agreed-to Best Practices. The most effective way to protect yourself and your organization is to become familiar with any standards and certifications that specifically affect you. Many standard-writing and certifying bodies maintain libraries and definitions that are available to you; some will also have standards collections that can be used. Understanding an appropriate standard and its intent will help you quickly identify questionable sales and marketing approaches. MT

My Take: Looking At The Bright Side Of New Energy Regulations

jane_alexanderAs July is heating up, so is the national debate on energy and how we’re going to be using and paying for it in the future. I’ve asked myself why I feel compelled to wander into this minefield and risk being accused of politicizing our magazine. That’s not my intent; I’m just making observations—and continuing to gently pester you about one of the most critical issues of our times.
