I don't want to have to put two or three 9-volt batteries together just to get the right power. Do I use a transformer for this? If so how do I do it and what kind? Thanks

first you have to change it to ac.then use a transformer.i suggest you dont do it .just go and bye a simple transfromer and use the line .batteries are no good in this case

A transformer won't work. They only work with AC. Batteries are DC. If you are talking about a 9 volt transistor battery it will not power a motor any larger than a thimble anyhow. If you have a 9volt battery that weighs a couple of pounds it will run the DC motor at a reduced speed. Your best bet is get two motorcycle or automotive batteries and connect them in series (24 volts). This of course depends on the size of the motor.
A small battery will not run most motors. You couldn't start your car with eight flashlight batteries (12volts) for the same reason. Motors require many amps and although small batteries may have enough voltage they cannot deliver the required current.

A transformer will not work with a battery as it is DC (Direct Current). Transformers only work with AC (Alternating Current).
You can get a converter but believe me, by the time you pay for the inverter and the measley power you would get out of a 9 volt battery, it just ain't worth it.
Find a 24 volt power supply of sufficient amperage to do the job.

It would be cost effective if you add batteries to get the right voltage. you cannot use transformer in DC voltage

Use the Switch to increase the Voltage.

Try something like Maxim's Step up voltage converters. See

this seems like a Rube Goldberg type of question. Maybe you theoretically could, but it's very a impractical solution.

use a step up transformer
