Question

hi..!!

i hav a project in whch m using two 12V dc geared motors..the current rating of the motors is 0.6A each..my queries are:

1.should the power supply be of 12V,1.2A?

2.wat will happen if i use 9V dc batteries instead of transformers??

3.wat precautions should be taken so that in any case the motors are not damaged?

4.how can i increase the torque(speed not a matter in the project)??

suggested readings are acknowlged..

thank u!!

Answer 1

1. maybe, but more margin would be better, as motors have a higher current on startup. Get a 2 amp or 3 amp supply.

2. These are DC motors, you can't use AC, so a transformer is out.

A 9 volt battery may make the motor move but slowly, and the battery won't last long. Get a plug in DC supply, rated at 12v and 2 or 3 amps.

3. Don't understand your sentence.

4. Gears can increase torque at expense of speed.
