what is the difference in the dc motor from the usm?

USM stands for Ultra Sonic Motor, which means that it's silent because there are magnets in the lens instead of a motor to focus.This is Canon's line of fast and silent focusing lenses. & DC stands for defocus control. This gives you variable bokeh - you can twist a ring to change the appearance of the out of focus areas (without altering the sharpness of the in focus area.)

As far as I know, the USM cannot process huge data. So, it is for flash drives only.

Both, in fact the machine has a in built transformer that can handle any domestic electricity, the motor I think is 12v, all you need is a plug adaptor, I needed a US to UK, and away we went. Amps is key so don't plug into your local nuclear power station.

I don't know the difference but I have the U8000 and it does have the quick release.

Hello. It depends on what vehicle size you are using it in. I used this as a replacement from the horrible 12T motor in the basic Stampede for my son. The difference is a little bit more speed and a little less torque. Example; the higher the turn motor = more speed and slightly less torque. The one thing I can verify, is that these motors are very reliable even if not broken in properly. Hope this helps!

Go to www.servocity. com. You will find the same motor there. They list all the specs.

I don't remember. I only use the motor in my CNC machine. It has been a great motor though and when I finally burn it up (it runs for long periods of time-15 to 30 minutes at a time between bit changes) I will be buying another. In fact I have been thinking of getting another now to keep on hand.

No differences physically between the two. I work with aircraft and require low torque and 1/4" drive is perfect for that!

It shows it on the board. 1 side says motor (which is dc out) and 1 side says power (which is dc in). good little pwm. i use them for driving water pumps in hydrogen generators. built pretty good for the price.

I don't think there is a technical difference, but this does have a very strong motor, I rarely use it on a high setting. Also This a an amazing product, not an amazing product for the price, but a plain amazing product! The price is just icing on the cake.

no it doesnt make a difference. most motors will run on voltages from 105 to 125 volts.

To be completely honest, I don't know that there is a difference. At first I thought the motor might be a bit stronger in the 1700, but they both say 450 watt. Sorry I couldn't help any further than that.

This is a variable speed motor. I am very rough on the motor, and it's really taken a beating. I love it! I recommend getting the MinnKota 60 amp breaker as well to protect the motor.

To the best of my knowledge all non-STM motors result in lens noise while recording. The other review sounds like they were confusing the full time manual (FTM) focus feature of most USM lenses as somehow creating more noise than non-FTM lenses, not true. STM lenses are specifically engineered to have a slower more controlled AF while recording video, thus producing less noise than all other Canon lenses.

the ultra takes 2 D batteries where as the basic one takes AA. Therefore works longer.

None of the other answers are correct. It's 900 Newtons DC, which is equivalent to about 0.8 (a touch better than 3/4 hp) AC motors you're comparing to.

According to the instructions it does come with a DC motor. Go to Panasonic's web site and read their product description. I don't know how difficult it would be to remove the circuits that convert 120 volt to DC. I would try a marine supply first to see if you can buy a DC fan that you could wire directly.
