I have some DC motors disassembled from a printer (HP Business Inkjet 1000) and need to know their working/maximum voltage. Searching the motor's model name in google revealed nothing.
The printer works on 32 volts (!), but I doubt all that juice arrives to the motors.
In its current condition, there's no chance to test the voltage while printer is running.
Besides a trial and error approach that might fry the motors - How can I find the correct voltage for each motor?
