Electronically Controlled and Electronically Protected Motors for End-Product Manufacturers
Date: July 7, 2010
UL has published its new family of motor Standards partly to address these challenges. Though it is well beyond the scope of this single paper to completely address the implications of this new, emerging and very much still evolving, technology on motor safety, let us address the fundamentals.
This whitepaper is geared toward providing information to end-product manufacturers of motor-operated appliances.

New Mini-Compressor: Could This be a Game-Changer?
Date: October 14, 2009
Refrigeration compressors powered by direct current (DC) electrical energy have traditionally been relegated to mobile refrigeration systems, where batteries or vehicle alternators are the source of power. The number of DC compressors produced today for the worldwide market is tiny when compared to the number of AC compressors, mostly reciprocating, rotary, and scroll types largely used in refrigerated appliances and air conditioners. But a recent development, the emergence of solar power and to a lesser extent fuel cells has provided added lift to the entire field of portable power. The result is that mobile refrigeration and portable cooling have been re-energized (both metaphorically and figuratively) creating new opportunities for innovative appliances that do not rely on grid power.

Solving the Problem of Motor Protection from Moisture, Water and Dust in Commercial Refrigerators
Date: September 30, 2009
Moisture, water and dust are common reasons of motor failure in commercial refrigeration applications like supermarket refrigerated display cases, beverage merchandisers and vending machines. Motor manufacturers address these concerns by listing their motors’ IP ratings, but often a more detailed explanation is needed. This white paper discusses the meaning and effectiveness of different motor IP ratings in commercial refrigeration applications, and illustrates in detail the Wellington ECR motors solution to moisture, water and dust protection compared to other common types of refrigeration motors.

Customization Is Key To Optimum Performance
Date: February 1, 2008
The ambient environment surrounding a thermal control can have a big effect on how the device operates. No two application environments are exactly alike, even though the applications may share a similar function. The materials used for an appliance as well as many other design considerations vary from product to product. These variations greatly effect the operating environment of many products.

Coordinated Circuit Protection for Electric Motors, Transformers and Control Units in Home and Professional Appliances
Date: February 1, 2008
The electric motors, transformers and controllers used in home and professional grade appliances are often subjected to mechanical overloads, overheating, stalls, lost neutral, severe overvoltages, humidity and other damaging factors. New polymeric positive temperature coefficient (PPTC) devices are designed for operation at line voltages of 120 VAC and 240 VAC, and can help appliance designers prevent safety and fire hazards, as well as reduce warranty return and replacement costs resulting from motor failure.

The Advantages Of Designing With Thermally Protected Varistors Versus Standard MOVs.
Date: February 1, 2008
Standard MOVs (metal oxide varistors) have been providing transient voltage surge protection from surges for many years. These surges can originate from lightning, electronic switching, electromagnetically induced surges and a myriad of other sources. MOVs are specifically designed to protect electronic equipment from overvoltage transient surges however they are not designed to protect the same equipment from a temporary abnormal overvoltage.
