An idea. A New Powerful Motor, with Huge Fans.

[Scaniabebe]

Just an idea I had been thinking about.
As we know, the older vacuums often have more power than newer vacuums as the old motors rely more on airflo than Wattage.

My HVR200-A has 1200Watt motor, but isn't as powerful as my neighbors 1980s HVR200. So, here's my idea. Why don't Vacuum companies put 1200Watt motors in, but attach large, old fashion fans?

Ideas, please?

It is simple, big fans cost more, stupidly high power motors with small fans are cheap.

Similar setups were done in the late 90s and early 2000s here in America. Hoover, DirtDevil and Eureka took their Elite, Featherlite and Bravo motors, which normally ran around 7amps, and allowed them to pull 12amps. You had the large direct air fan and the RPMs of a 12amp motor. They were all discounted around 2005.

I bought a 12amp direct air Featherlite in 2004, and the hose suction was amazing. They were a little loud, but really nice vacuums.

NSS M1 "Pig" commercial vacuums have a large motor and a LARGE fan--They work on AIRFLOW more than suction "pressure".My Tornado wet-dry vacuum has a large motor and and large single stage fan-and a bag as an external filter.I would think these vacuums could equate to the large fan and motor.Good thing about NSS M1's is their relatively slow speed-big fan turned at low speed-12,000RPM max-most other motors can be about twice that.and more noise-shorter life-and if its a direct air vacuum-more likely to suffer fan breakage from hitting a hard item.The NSS vacuum can eat hard items if they get into the fan.conduit box knockouts are an example.Bends and folds them!

I wish companies would actually revert back to the 7.2 Amp uprights and 9.3 Amp canisters like Hoover had and be more energy efficient to save electicity. Either that or make more efficient 12Amp motors. Some 12amp motors are weak and some could suck the paint off your walls. I personally was very impressed with 9.3 amp Hoover PowerMax canisters they had better suction and outperformed 12Amp Eureka Worldvac canisters I thought. The Eureka WorldVAcs were still good and love the fact that Eureka was donating money to save forests with purchase of Worldvacs.

I've seen but never tried a 12Amp Elite, do those seem much more powerful than their predecessors?

Please note-and this could relate to the part in another thread about concern of power draw of vacuum cleaners.Just becuase a motor is marked 12A doesn't mean it is drawing that much when used in a vacuum cleaner.that is a lab derived figure-it means the motor when it is connected to a dynameter-the max load it can be loaded to without damage.Universal type motors as used in vacuum cleaners,appliances and power tools can draw their max rated current when heavily loaded-power tools is the best example.Under most use the motor is drawing well UNDER its nameplate rating.

I completely agree, I get sick when I see that are vacuums that it's wattage is as high as 2500 watts, it's such and unnecesary waste of electricity when a 1000 watts motor can do the same job.
But as Jmurray said, when the fans are bigger, they become more expensive. Also, the vacuum cleaners are much smaller than they used to be years before, so the manufacturers put smaller lightweight motors that could fit its size. The small fans can't move the same amount of air, so that way, the motors needs more energy and of course, that increase in the motor rpm causes overheating, a huge energy consumption and (of course) it made them screamy loud.
Of course the solution is simple, I don't think it would be a problem to make bigger motors and reduce the wattage, the problems are that the market sells the vacuums for their wattage, making people think that if the number of whatts is bigger, they will be more powerful, when it's AIR WATTS/AIR FLOW whats it makes a vacuum cleaner more or less powerful.
In conclusion, if the demand of the consumers are small, cheap, vacuums with high speed motors (and they do sell well), the companies will still produce them, it's everything about marketing.

WOW! I didn't realized how much I've written, I could go on and on talking about it hehe.

Have a grrreat day guys!
