Motor and Battery!

Hey everyone,

I built a motor for my physics exam....and it works extremely well....it spins extremely fast and there are sparks galore on the commutator.

I have it attached to a 6V lantern battery (the ones a bit bigger than your fist).

How long can I expect the battery to keep powering the motor at high speed? Surely if it's that big of a battery, and the circuit is shorted for a split-second...I can expect to keep running the motor for a long long time?

There is no way to calculate that without knowing a lot of details about resistance, etc. in your motor. If it's important, hook up a battery and time it.
