The Simple DC Motor

Intro: The Simple DC Motor

A simple project to show you how to make a dc motor at home.!!

STEP 1: Starting to Built

1. Hold the loop vertically by placing your thumb through the center of the rotor Place one
of the straight sections of wire on a flat surface. Using a razor blade, strip ONLY the
TOP surface of the wire. Be sure not to strip the sides or the bottom, just the top. Strip
the wire from the coil all the way to the end of the straight section

STEP 2: Preparing to Assemble

2. Strip the other straight section of wire completely – top, bottom and sides.
3. Prepare to assemble the motor.

STEP 3: Twisting Paperclips

4. Place the ceramic magnet in the middle of the wooden base.
5. Bend two large paperclips as shown below.

STEP 4: Proper Arrangement

6. Using thumbtacks, secure the paperclips to the wooden base. Secure one paperclip at
each end of the magnet.
7. Place the rotor in the paperclip supports. When the loop of wire is oriented vertically, the
plane of the loop should be directly over the magnet. Adjust the magnet and/or supports
accordingly.
8. Attach the battery snap to the battery. If desired, secure battery to base using electrical tape.
9. Touch (or secure with electrical tape) the black lead from the battery snap to the
thumbtack that is securing one of the paperclips.
10. To complete the circuit, touch (or secure with electrical tape) the red lead from the
battery snap to the thumbtack securing the other paperclip.

STEP 5: Help

• Has the rotor been stripped correctly? Hold the plane of the loop so
that it is oriented vertically. One of the straight sections of the rotor
should be stripped completely (from rotor to end); the other straight
section should be stripped on the top only.
• Is the circuit complete? Check each connection: red lead to
thumbtack, thumbtack to paperclip, paperclip to stripped section of
rotor, other stripped section of rotor to other paperclip, paperclip to
thumbtack, thumbtack to black lead. Any break in the circuit will
prevent current from flowing and thereby prevent motor from
working.
• Is the rotor level and directly above the magnet? Adjust the rotor,
paperclip supports and magnet until both straight sections of the
rotor are perfectly horizontal, both paperclip supports are at the
same height, and the magnet is directly underneath the rotor when
the rotor is oriented so that the plane of the loop is vertical.
• Is the rotor close to the magnet? The magnetic field is strongest
nearest to the magnet. When the plane of the rotor is oriented
vertically, the bottom of the rotor should be as close to the magnet
(without touching) as possible.
• Is the battery providing power? Use a voltmeter or multimeter to
check the voltage of the battery or simply replace with a fresh 9 volt
battery.

where did you get that magnet wire?

[Avinash Sinha]

I got it from an electric appliance repairing shop.. You can get it from any electric tools shop where they either repair fans and motors or have their spare parts... Ask for enemeled copper wire

When you make one these send me a picture of your project..!

[OJX]

Can I use a non-coated copper wire instead of insulated copper wire?

[Avinash Sinha]

I'm sorry to say but you cannot.

Explanation: If you use non-coated copper wire it would act as a not even a single turn of wire as the electricity would take up the shortest end to end path... But if you take coated copper wire WHICH YOU SHOULD will let the current flow in loops of coil which will create much better magnetic field which is required for the project..

Happy ? to see you respond... Avinash Sinha

Quick Question... What is the point of only stripping the top of the one rotor wire?

[Bot1398]

Its because its a enamel coated wire and enamel does not conduct electricity so we have to remove the enamel .

[tesla man]

Well i know that, But why do you only strip the top part of the enamel coated wire.

[Avinash Sinha]

as when it gets electricity it becomes a electro-magnet and in electromagnet electrons and neutrons must not be combined everywhere

[Electroinnovation]

You may want to change your description of the wire. You have it as AWG wire...AWG is a unit of measurement for the wire. An actual kind of wire would be something like 22AWG wire or 12AWG.

[Avinash Sinha]

thanks and sorry for my bad english

[iPodGuy]

You know, I could see myself making one of these but I really, really wish you went more in-depth on making the coil (hew many turns, etc).

[Avinash Sinha]

40 is okay for 9v

[Kiteman]

The number of turns on the coil isn't vital.

[Avinash Sinha]

at least 40

hay u got reply fro him then post to me allso
