Motor Information

The most important component in any central vacuum system is the motor. There are four major suppliers to the central vacuum industry, Ametek Lamb Electric, the German made Domel, GS Motors and most recently the China made motor. These companies make several different motors which a central vacuum manufacturer can utilize. Some of these motors differ dramatically in cost, performance and reliability. When comparison shopping also look at the motor warranty. Simply put, the longer the warranty the more confident the manufacture is in their product.

News Flash
Europe's Largest Motor Manufacturer Selects America's Largest Parts Supplier as Exclusive U.S. Distributor

VCP International is proud to announce that it has won the rights to be Domel's soul source for distribution in the United States. Ironically both companies started in 1946, VCP in Dallas, TX, and Domel in Zelezniki, Slovenia. Both also had broader focuses and have since specialized in their niches. VCP started as a wholesaler for all small appliance parts, concentrating strictly on vacuum cleaners beginning in 1965. Domel started producing office equipment developing its first motor in 1953. Domel now manufactures vacuum cleaner motors, universal commentator motors, EC motors, DC motors, ventilators and asynchronous and synchronous motors.

VCP Owner and CEO Don Russell said, "We have been talking to Domel for about a year and a half, both companies doing their inquires and us doing our market research. We then came to the conclusion that there was a real opportunity for a quality motor manufacturer such as Domel to do tremendous business in the U.S. and Domel thought VCP was the one to do it.

Russell continued, stating, "After a team of VCP employees went to visit Domel's factories in Slovenia this spring, we then knew what we had heard was true, Domel's quality does blow away the competition."

By the year 2009 more than half of the central vacuum industry will be using the Domel motor as more companies have started to recognize the quality and longevity these motors provide.

Domel has over 60 engineers designing motors. This is more than five times the main competition. Domel Inc. President and CEO Peter Korosec, said "We are very excited to bring our high European quality and longer life motors to the U.S., and especially working with a quality company like VCP. Our support team is looking forward to helping VCP service the U.S. market.

5.7 vs 7.2 Diameter - Whats Better?

Typically 95% of most central vacuum manufacturers now a days use the reliable 5.7 two stage hi-efficiency (German made) Domel or Ametek Lamb motor. These motors usually spin an average of 21,000 RPM. Among manufacturers who use the 5.7" impeller series motor in their most popular models are Drainvac, Dust Care, PowerStar, WalVac, Honeywell, AirVac, Beam®, Electrolux®, Eureka, Modern Day Hoover, and Smart Vac etc.
Drainvac, Dust Care and soon Beam
® use the highest quality German made Domel double ball bearing motor, that same motors used in Miele vacuums, the most powerful vacuums in the world. The Domel motor is now also featured in ProTeam Commercial Backpack vacuums, the industries best backpacks, to insure the longevity and quality their known for.

The German Domel Premier Line of motors utilizes all steel construction, double ball bearings, no-load fan, and have proven superior to all other Ametek Lamb motors under controlled testing. Simply put these motors are the best motors available for central vacuum applications.

* Average Life of a 5.7 Motor - 18 to 22 Years or More. (High Efficiency)

Ametek Lamb also makes a 7.2 diameter motor, called "Premier" (Part#115334) their most durable motor ever, which is being used in most all cyclonic motors.  These motors will move air (CFM) at slower speeds (RPM), thus extends motor brush life (1,200 hours) and bearing life. The lower speed creates a twirling effect or tornado inside the canister called the "cyclonic configuration" effect, however this lowers the power (air watts) as well as the CFMs and water lift which will also lower your suction. This does not provide more power, but in actuality lessens it.

* Average Life of a 7.2 Motor - 18 to 22 Years or More.

Impeller Diameter
This is directly related to the volume of air (CFM) a motor is capable of moving. Many manufacturers use the (America made) Ametek Lamb & (German made) Domel motors which have a 5.7" impeller in their most popular models. Because these motors are universal motors, and require motor brushes, impeller diameter also affects motor brush life. Because of the small diameter of the impeller, RPM is increased to allow the impeller to move at least 100 CFM. Carbon brushes should be replaced every 800 hours on a 5.7 motor and 1200 hours on a 7.2 motor with normal household use. Takes only minutes to change and extends the life of the motor adding years of trouble free performance.

Motor Definitions & Terms

The Higher The Air Watts... The Better The Pick Up!

Airwatts is a combination of water lift (suction) and CFM (airflow). This is the truest measure of cleaning power. 99% of all central vacuum manufactures measure the power of their units by Airwatts. Maximum Airwatts is recognized by the American Society of Testing and Materials (ASTM) as the best way to measure the actual cleaning power of a central vacuum system. Other misleading terms such as Airflow, CFM's and Waterlift are not a true measurement of power, but rather part of an equation that equals Airwatts.
Airwatts = CFM's x Waterlift divided by 8.5
u

 

CFM's x Waterlift divided by 8.5 = Airwatts

 

u
This measures the "volume" of air the motor is capable of moving and works in tandem with "Suction". Airflow can be a bit confusing however, since performance measurements are taken from the motor and do not factor any resistance found in a typical central vacuum system. Filtration, piping, hoses and accessories all restrict and reduce the amount of actual Airflow a system has. While Airflow is important to system performance, Suction or the "pulling of air" maintains the Airflow velocity necessary to sweep dirt and debris away at the hose end where vacuuming takes place. CFM is NOT a true measure of suction, however it is a form of measurement and part of the equation when measuring Air Watts. This is a misleading measurement of suction power. Please note certain companies will lower this number in order to inflate the waterlift. This is done to influence a consumer by making the suction power appear stronger - Wrong!
 

CFM's x Waterlift divided by 8.5 = Airwatts

 

u
This measures the suction strength of a central vacuum motor. Essentially, it tells how much "pull" or "lift" power the motor has. This measurement is always taken at its maximum value, the 0" inch orifice (sealed vacuum) where suction is at it's greatest. Since this measurement is taken from the 0" orifice, it is very misleading. This measurement does not take into account piping, hoses or accessories etc., thus giving a false measurement of power. Often referred to as Inches or Waterlift or Vacuum, Suction is vital to overall system performance since it is the "pull power" that maintains Airflow though the complex network of vacuum pipe, hose and accessories. While Airflow is necessary for a vacuum cleaner to work, suction creates the lift and velocity of air which sweeps dirt away. Waterlift is NOT a true measure of suction, however it is a form of measurement and part of the equation when measuring Air Watts. This is the most misleading measurement of suction power. Please note certain companies will inflate this number to influence a consumer by making the suction power appear stronger - Wrong!
