motor

hi
can i run 12v 300rpm dc motor with 5v supply.
i am not doing any programming just want to give supply to motor and run it.
will 5v supply run this dc motor.

The motor can run very slowly if it is rpm is more.

can i calculate how slow will run.

You haven’t provided the datasheet or product page for the motor or the DC supply. Both
are needed…

A DC motor under ideal conditions runs at a speed proportional to voltage. However load and friction influence the linearity.

Assuming your motor runs at 300RPM at 12 volts suggests it has a speed reduction gearbox.

Assuming ideal conditions the speed with a 5volt will be 300 x 5 / 12 = 125RPM

You are not thinking of running this motor directly off an arduino pin, are you?
