Why your home’s (120v 15 circuit) does not overload tools that only use 1 amp, 2 amps, 3 amps (etc. anything less than the 15)?

Question

For example if I connect a 90v motor to a 120v battery source doesn’t that overheat and blow my motor?

Why is it though when it’s 120v from the wall then the motor is still fine?

Easy simplistic way to think of it. Voltage is pushed, current is pulled.
120v to your 90v WILL overheat it.
15a available at 90v to your motor WON’T overheat it.
