if i have a 12v electric motor, will it last longer if i give it less voltage?

a bit

No not really, what usually wears out is the brushes or the commutator, they are a direct contact pair, the only thing that would make it last longer would be running less RPM's, but only a small amount of incresed life span, nothing you would notice. I guess in theory the decreased voltage = less rpm's, so the answer is yes... sort of, but not really LOL

hmm ok

SUUUUUURRREEEE!!!

Decreasing voltage wont increase the life at all. The brushes and commutator wear becouse of constant friction. That will stay the same regardless of what voltage they see. The only way voltage really has an effect on a motor's lifespan is in the windings themself. That is where all the action takes place. less amount of turns of wirewith a thicker gauge wire give you more torque and current carrying ability, lots of turns with thin wire give you super high rpm's.
The main thing is to never over juice a motor. That why us guys with hydros allways have trunk fires. We take a 24 volt motor and run between 36 and 96 volts to them @1000+ amps. They don't last long, but damn they move! |
whoa mike has a serious question. AMAZING!
