Stain's homemade electric motor.wmv

A simple homemade electric motor serving no useful purpose apart from cosmetic or educational. Two magnets spin on the armature. One of them triggers a reed switch while the other, in a sequence, gets pulled towards the electromagnet which is a length of enamel insulated magnet wire wrapped around a short roofing bolt. The reed switch momentarily energizes the electromagnet but switches off so that the magnet doesn't stay in place, thus enabling continuous rotation.

Nice of you to comment, happy to help. The green component is .01uF capacitor, it's purpose is to reduce the spark inside the magnetic reed switch, connected in parallel. The sparking welds shut the contacts inside. Unfortunately, the reed switch needs frequent replacement because they burn out: this isn't a faultless design. One way to start is making an electromagnet, which is some 26 guage magnet wire wrapped arount a steel bolt. Each end, connected to a battery makes it magnetic.

does it have electric magnets?

@TheAjovalo68 Hi! There is an electric magnet (what I call electromagnet). This is the barrel shaped thing which is a coil of wire wrapped around a short roofing bolt. Thank you for your question! :o)

nice and smooth, i made one myself last month

@paddy9934 It's fun to make electric motors. Thanks for your comment

Thank you mcorrade. Nice to have a comment. :o)

it will be nice if when a switch is there

cool, but i think the camera is a little too close to it hehe

[jcalteaux]

could you explain in a little more detail how you did it? I see that green component in the front and i would like to know what that does as well. Any help you could give me would really be appreciated.

very cool!!!!
