Visit The Motor Doctor

We've put on hundreds of seminars all over the country and have written a regular series for a number of trade publications. Now you can visit the Motor Doctor on the web, and I'm looking forward to sharing my 30 years of motor experience with an entirely new audience.

A. O. Smith introduces two new variable speed solutions

One size does not necessarily fit all, particularly in residential heating and air conditioning applications.

A. O. Smith Electrical Products Company is introducing two "comfort speed" fan motors to meet the extensive requirements of HVAC manufacturers--and the wide-ranging variety of applications in the residential market.

• The new Gemini ™ motor contributes to improved system efficiency and quiet operation, particularly at lower speeds.
• The Gemini Plus is a series of fan and blower motors that consist of motor and built-in electronics.

The two new motors will be unveiled at this year's AHR Expo at the Anaheim (Calif.) Convention Center, Jan. 26-28. A. O. Smith Electrical Products Company will be exhibiting the motors in booth 6529 at the show.

The company also will discuss a third comfort speed solution that it expects will be available later this year. The new motor features sophisticated electronics and programmability to provide a variable-speed solution for high-end applications. The electronically controlled motor is designed to deliver constant cubic feet per minute (CFM) to enable customers to obtain the most efficiency out of their heating or cooling systems.

"These new motors enable our customers to enjoy the many benefits that a 'comfort speed' solution can provide without having to pay the premium price associated with variable speed motors," Chris Ruttle, senior vice president-global sales and marketing, A. O. Smith Electrical Products Company, points out.

"Taking advantage of our family of comfort speed products, customers will be able to match the motor to the application and gain the right mix of features and benefits for their HVAC systems," Ruttle adds.

The Gemini motor is actually two electric motors in one. The innovative design mounts two separate rotors and stators on the same shaft in the same main frame. Each motor comes with multiple taps so that the customer can isolate high speed operation and low-speed operation for improved system efficiency.

"By using a second synchronous speed motor during low-speed operation, the customer can obtain greater speed separation," David Reeder, product planning manager-HAC motors, explains. "The installer can select the right speed tap for the individual residential application."

The Gemini motor offers quieter operation than conventional permanent split capacitor products and is easy to install.
The Gemini Plus comes with electronics that can be pre-programmed to match the low speed performance with the high speed that the installer selects for the specific application.

The moisture-resistant electronics in the Gemini Plus are well-suited for heating and air conditioning applications, and there is no need to install relays or other additional components. The Gemini Plus motor also offers quiet operation at low speeds.
Both the Gemini motor and the Gemini Plus offer homeowners a number of comfort benefits:

• More consistent temperatures thanks to constant air circulation at reduced speeds. This eliminates stratification in the home;
• Cleaner air--When the motor runs in the continuous operation mode, it continually circulates air through the filters or electronic air cleaner;
• Better humidity control--In continuous operation mode, the motor can allow furnace humidifiers to work more effectively, while the constant air flow over an air conditioner's evaporator coils helps remove moisture;
• Enhanced system efficiency at high and low speeds.

A. O. Smith Electrical Products Company is a leading manufacturer of alternating current (A/C) and direct current (D/C) fractional horsepower motors, hermetic motors for air conditioning and commercial refrigeration compressors, and integral horsepower motors. The company employs approximately 13,000 people at facilities in the U. S., Mexico, England, Ireland, Hungary, and China, and serves customers worldwide.
