Re: [DMCForum] Re: [DML] 50 Worst Cars-What Moron Wrote This? (Electric Motors)



Bill,

I said "virtually" forever. ;-) I also wasn't talking about
locomotives. The electric motors powering factory equipment 24/7 in a
food processing company I once worked for were older than dirt and
still running fine. Electric motors powering consumer vehicles will
last virtually forever. Everything else in the car is going to fall
apart and fail long before the motor, typically.
