I need an electric motor for a battery operated cutting tool that I'm developing. All major search engines seem to provide an overwhelming amount of product that doesn't match what I'm looking for. If anyone knows a great place to find electric motors, gears, and shaft connectors, it would be greatly appreciated. The approximate specs of the motor I need are: 12V DC, an offset shaft gearhead with an output speed greater than 5,000rpm, and a diameter less than 2".

please somebody explain how you would measure the current flowing through a DC electric motor when it is operating..... PLEASE HELP!!! :D :D

hey i have four questions for yas most apprieciated if you can help!!! Question 1 Where does the energy that makes the DC electric motor work originally come from? Question 2 What difficulties would you have measuring the current flowing through a DC electric motor when it is operating? Question 3 Please Explain how you would calculate the resistance (in ohms) of a DC electric motor circuit. Question 4 PLease name as many appliances that have electric motors in them please and thank-you if ya answered!!! PEACE OUT :D

How can I calculate how much weight can a DC electric motor carry? I want to useit in elevation device to carry the weight for one meter height. I have to use two battries only that supply 3 volt , The speed of motor is 5240 rpm
