I am building a small toy boat from basically nothing and was wondering if the 9.6 volt battery pack would damage the 3 volt DC motor used to propel it. The motor doesn't seem to get hot or sound bad when it's running. Will it hurt the motor at all, even if not running for very long periods of time? Thanks in advance to everyone helping!
It might hurt it. The rpm is running 3 times the normal rpm. It would be best to measure the amps used with a voltage meter running on 3 volts. Then use a resistor of the correct size to make the amps with a 9. volt battery pack. If you dont know what ohm search for ohms calculator put in 9.6 volt and the amps you measured from the 3 volt. It will calculate the ohms for you. You can find resistors are radio shack get a larger one rated formore than twice the wattage used (wattsamps x volts)
