Need help choosing a dc motor!!
My students are building model cars our of balsa wood that move b/c of a dc motor. All of the motors I have are burning out - they can't run long, I used to have a dc motor that started out slow, built up speed and then ran fast and for a looooooong time. Does anyone know what type of motor i'm talking about? please help.....i gotta get them asap. thanks!
