Does a regular desk fan work the same as an electric car motor?

Tuesday, March 5th, 2013

Question by Ghost: Does a regular desk fan work the same as an electric car motor?
I like working with motors and machines and making things go and i figured since they figured out how to make an electric engine powerful enough for cars that i could trick out my fan to run at like a hundred MPH Lol So to get familiar with motors like that, I’d take my fan apart but do they have like the same concept behind them or what?

Answer by Allan
Normal desk fans use an AC induction motor which operates on a different principle to that of the DC motor found in a car.

Can an electric motor be used as a generator?

Friday, December 7th, 2012

Question by Extra: Can an electric motor be used as a generator?
With no extra components being added? I mean, by just driving the shaft of the electric motor can you power an electric device like a generator?
by any chance can anyone give me an example of this kind of electric motor?
also, can these motors be used for electrically powered automobiles?

How is motor designed for 110v differ from a motor designed for 220v?

Saturday, November 17th, 2012

Question by taj: How is motor designed for 110v differ from a motor designed for 220v?
I would like to know an electric motor (like for example a washing machine motors) designed for 110 volts power will be different with the same motor designed for 220volts. In another words how can I modify an electric motor designed for 110 volts to be able to run with 220 volts power? I do not mean using a transformer to convert power source. My question is how can a motor itself can be modified?
Thank you for your answer.

HELLO

FIRST I REMEMBER YOU THAT ONLY SOME ( FEW ) TYPES AND MODELS OF ELECTRIC DEVISES WORK WITH BOTH 110 AND 220 .

NEXT I TELL YOU THOES MACHINES THAT WORKES WITH BOTH ( 110 AND 220 ) ARE IN TWO TYPES :
1 .MACHEANS THAT HAS A KEY BEHIND IT AND USER CAN CHOOSE 110 OR 220 ,
2 .MACHEANS THAT HAS INTERNAL ELECTRIC DEVICE TO FINDOUT THE VOLTAGHE OR REDUCE IT FROM 220 TO 110 .

( I ALSO REMEMBER OU SOME ELECTRIC DEVICES CAN WORK WITH BOTH -AC- AND -DC-
POWER ( 12 DC AND 220 OR 110 AC ) )

AND NOW THE DIFFRENCE :

THERE IS MATHEMATICAL ROOLS BEETWIN AMPER AND WATT AND VOLTAGE AND …

ENGINEERS CAN BUILD DEVICES BY USING THESE FORMULAS TO BUILD A DEVICE .

FOR EXAMPLE , DIAMETER OF CABLE OF ENGIN ( SHELLED CABLE THAT COVERD WITH MAGNETS ) OR NUMBER OF ITS ROUND MAY DIFFRENT FROM 110 DEVICE TO 220 .

( ALSO I CAN REMEMBER YOU THAT FREQUENCY OF 220 V IS 50Hz )

What is happening in the motor generator unit of an electric train when the train is:A)speeding up B)slow down

Answer by billy
Several things can happen, most often it is because the wheels or the top of the track is dirty and they don’t make good contact in certain places and in other places they do. Clean them both good. If its in the motor then the contacts inside the motor are dirty, they can be cleaned but you have to know what you are doing and be careful to get it all back right. Sounds like track and wheels though.

Could an induction motor be used for regenerative braking in electric train control?

Answer by johnm
Sounds possible. See http://en.wikipedia.org/wiki/Hybrid_train. I see it as a real possibility for lighter passenger trains. It might take development of special batteries for the heavier trains.

How do i mount a small electric motor on a piece of balsa wood?

Wednesday, February 1st, 2012

Question by : How do i mount a small electric motor on a piece of balsa wood?
I am making an electric train with a balsa wood base, but the electric motor i bought did not come with a mount. I need to figure out which kind of material is light, easy to use, and will hold my motor securely. If you know how or have any suggestions, please tell me!

Best answer:

Answer by jeffrey l
Ben,
you can use western red cedar, this timber is very light and will hold screws better than the Balsa, .
build an arch to fit around the motor on a cedar base , a thin layer of neoprene rubber will stop the motor slipping , and absorb any stress on the mount,.

you could also use 2 electricial zippy ties to secure the motor to a light ceadr base, or if you can do some basic metal work and have access to light guage aluminium, you could use the alloy instead of the cedar.
