Are there any good small motors that are quiet but powerful enough to move a lot of air? Is there a better way to move air then with a fan? This is for a project I am doing; the motor or other contraption should be the same size or smaller than the size of an average electric shaver, in other words, not too big.

There are those pancake fans they use for electronics, like in your PC's power supply.

as you are looking for ideas and trying things (which is good) don't forget that there are experienced engineers out there who design fans as their job
if you want to come up with something different than what is available you are going to have to think way outside the box
engineers already choose the quietest, best-air moving, most economical designs
they have not just neglected a kind of motor, or battery, or power supply, those are considered
so, use the internet to look at lots of fans for sale out there
then, if you are trying to do something different than those, you have to dream a real big dream
good luck

Be sure to study shaded pole motors. They are small and powerful enough to drive a fan but usually can be stalled without blowing a fuse or overheating the motor.

Your choice will be dependent upon your specific requirements.
If you wish to have a higher pressure, I suggest you use the centrifugal type. But if you wish to have a higher volume of air a axial type fan should be used.
You have to think first which one you have to give priority. A pressure or volume?
The motor size will also depend on your choice.

My boss claims that it is not the motor but the type of fan. He likes squirrel cage fans for moving lots of air quietly.

How about a reciprocating design with blades like a venetian blind? Or you could try something like the Sharper Image air purifier that moves air using electrostatics. I don't know that it would move a lot of air, but it would be fun to investigate.
