thanx philo it shows this new kind of motor is... pure... weak why it takes 10 times more current giving just 1/4 more rpm than 71427? and why it consumes almost 2 times more current with load? why they use it? i hope there were some cases (not only (...)

Hi, I've got a friend who has a couple of 9v motors that have a broken shaft. I'm not too sure where it's broken but was wanting to know if anyone has a link to a site that has the details on how to strip on of these motors down to repair them? (...)
