What stepper motor should I buy?

I am building a device that goes around a track at set times and am not sure which stepper motor I should buy. I know that it must be able to reach 2000rpm to achieve the quickest time required but don't know where to buy the stepper motor and which stepper motor would be best.The fastest speed the device will need to travel is 10m/s. I am also going to use an arduino to control the speed. Any responses would be greatly appreciated. Thanks

power wheels too much power?

So here da ting. i got a little 6v power wheels quad at a yard sale for dirt cheap. i figured hey why not ill work on it a little and make it nice. long story short, i ended up with two 18v harbor freight batteries hanging on each back fender like military ammo cans and it looks awesome but now its a little too scary to let my son ride it. i would like to put a voltage regulator on it to turn it up or down depending on how well he can ride it and how safe i feel he can be. most of the ones i have found can barely handle 2 amps. where can i get a regulator to handle the load continuously. p.s. this is the last part i have to figure out before i can make a full instructable.

Why do rc cars have capacitors on the motor? Answered

Being a hacker or at least a take-it-apart-er, I have seen what looks like one or more small capacitors (I think) soldered directly onto the motors of radio or remote control vehicles. Are these capacitors? I understand the reason for capacitors on large AC motors. Do they serve the same purpose on small DC motors?

Adjustment of the speed of a DC motor Answered

I'm working on something that requires a very low speed motor (~.5-4 RPM). I found a motor that runs at 1.5v @ a maximum of 7rpm (5040RPM max with 1428:1 ratio) I need however, something to lower and raise the speed of this motor. I know that people say PWMs for this, but the only one I can find is a 12 volt and has gotten mediocre reviews. Could I use this 12 volt PWM in this system, or could someone point me to a reasonable PWM that would work?

Electric Motors 1/6 - 1/2 hp Super Cheap!

Hey Instructable Community! I've fallen into a consistent supply of used electric motors and I'd love to offer them to the people in this community. I was going to start selling them on Ebay but I like you all much more than those randoms and I'm even willing to offer them to you for a lower price because this site has literally changed my life. Not to mention, I be you'll have a much more creative use for an electric motor. Details and Disclosures: These motors are used and are coming out of Air Conditioning Units that a buddy of mine scraps. (He installs units and takes the old ones) He was junking the motors for mixed metal scrap prices and I figured I knew some people that might value them. I have some 115v motors and many more 220v motors. These motors range from 1/6hp to 1/2hp. I test the 115v motors but don't have a current setup for testing the 220v motors. That said, they were working when the units were replaced. I am very flexible on price. Motors range from $25 - $60. (Plus shipping)  I'll go even cheaper if you want a few. After receiving payment I can usually ship within a few days. I'd also be willing to meet up if you are in the general Philly area! This is a great opportunity to power your next AMAZING Instructable. I promise to do honest business lest the Instructables staff delete my account. (I've got about 2 years of pro that I'm not willing to give up) I hope to hear from you all soon!!!

Help figuring out electric motors

I'm trying to decipher the mystical language of electric motors and need some help. I was at one of my favorite stores yesterday, a place called 'Industrial Liquidators' here in San Diego, and I was looking at their vast supply of electric motors. Big ones, small ones, battery operated ones, flat one, all in latest styles and fashionable colors. I know of plenty of uses for these things but I have no idea what it is I'm looking at. I would like to make my own rock polishing tumbler, so I'd like a motor with a bit or power and a slow rotation, but how can I figure out how strong and fast a motor is?Maybe I'm starting at the wrong place. I must admit that I know next to nothing about electrical stuff. Pretty much the only thing I know about electrical equipment is that it only works when you plug it into a socket.So that being what it is, can anyone direct me to a website that explains how to read these motor labels? Ya know the ones that say how many ohms, volts, amps etc.Thanks for any help.

Controlling anaerobic digesters with arduino

Hi I am new on the Arduino scene and I am trying to build eight anaerobic digester tanks to conduct experiments for my thesis in engineering. The setup will look as follows: -Arduino mega -Arduino motor shield R3 -Two motor stirring the digester at different RPMs. Motors will run at 12 V and around 0.5-1 A. -The motor shield will use the wall jack as power supply via an AC-DC adapter. -Biogas volume measuring device (tipping sensor) -Aquaria air pump to supply Hydrogen Sulphite consuming bacteria with oxygen. This will be controlled with a relay and the volume measuring device. -The pump will use the wall jack as power supply -Temperature sensors DS18B20. -Immersion heater controlled by the temperature sensor and a relay. The digester is supposed to be kept at 37°. Everything will be logged but I haven’t decided if I will connect a Ethernet shield or if I should log on a SD card. I think that I can manage to build it but I have some questions (a lot) but will just post some and post more later. The experiments will run for 4-6 months how will the Arduino, shield and relays handle being on for that long? Do I need something with higher quality? (It would suck to burn down the university) Any spontaneous thoughts that I should know or that could help me?

A basic (very basic) description of a Brushless DC motor.

So... before I start... I am not a physicist, nor am I an electrical engineer. Hopefully someone within one of those (or both) professions will chime in and enrich this discussion. That said... I'm going to be using leyman's terms. This thread is specifically meant to explain how a brushless DC electric motor exerts a force, and how that force is used to generate work. To start off, I'd Like to explain the components which comprise a brushless DC motor: First... You have an axil. The axil's purpose is to spin. Next you have natural magnets, or solid state magnet; I use the terms somewhat incorrectly, since a natural magnet refers specifically to nickel or ferrous base magnets, but there exist a large variety of compounds and composites that exhibit the ability to produce magnetic fields. In practice you have many in a motor, but for our purposes... we can pretend we have one. The natural magnet's job is exert a magnetic field while attached to the axil. After that we have an electrical coil. Once again, in Brushless DC motors, we have many of these, but for our purposes we'll use 3. The electrical coil's job is to produce a magnetic field which can move in a circle. Finally we have the engine housing. The purpose of the engine housing is to hold everything together. Note: I'm intentionally leaving out the computer control mechanism. there are alot of great instructables on microcontrollers. Most Brushless DC motors requrie one to work since there is no mechanical timing device, as there is in a brushed engine. So... how does this fit together? In this setup the natural magnet produces a force when next to the electrical coil (This coil is also known as an electromagnet). This is because the charge of the coil is opposite to the charge of the natural magnet. Once the Natural magnet and the electromagnetic coil align with each other, the first coil shuts off and the second turns on. Once again the natural magnet is drawn towards the magnetic pole. This process repeats until the natural magnet has spun in a circle (note: usually you want it to continue to spin beyond a single revolution.) That's the basic (very basic) idea behind a Brushless DC Motor.

Pager motors: Removing weight and driving wheels

Hello fellow life forms, I am currently working volunteerily at a local school, teaching young kids a bit about telescopes and astronomy. One topic I am currently planning is the mars rover(s) and I am planning on building a simple line follower as activity. As the budget is very low but I still want the kids to be able to build something to take home I am trying to keep it as simple as possible. After I ordered a pager/iphone motor a year back or so, I now ordered 100 vibration motors for $28.50 at aliexpress. http://www.aliexpress.com/snapshot/6020160679.html They work fine but are smaller then the one I had before, a rubbery encasing makes them the same form factor. http://www.ringohr.de/tmp6//motorbadpic001.jpg  http://www.ringohr.de/tmp6//motorbadpic002.jpg  (excuse the horrible pictures, I just have a older android phone) 1) The first problem is removing the weight. I have searched and found several tutorials (for example http://www.robotroom.com/TinyMotor.html) and aproaces, heat and regular pliers failed, for everything else I lack smaller tools.   I consider ordering those grip pliers here in germany, which one would be better? http://www.ebay.de/itm/Gripzange-extra-kurze-Baulange-100-mm-Neu-nur-3-95-505-incl-Versand-/151165386645?pt=DE_Baby_Kind_Baby_T%C3%BCr_Treppenschutz&hash=item233228bf95 or http://www.ebay.de/itm/Mini-Schweisser-Gripzange-125-mm-mit-Feststellzange-Klemmzange-NEU-OVP-/261407967637?pt=DE_Baby_Kind_Baby_T%C3%BCr_Treppenschutz&hash=item3cdd210995 I also considered a watch wrist band tool as I have only a limited set of tools,  http://www.ebay.de/itm/Stiftausdrucker-Armbandkurzer-Stiftentferner-Uhr-Federsteg-Uhrenstift-Entferner-/370981549407?pt=DE_Elektronik_Computer_Haushaltsger%C3%A4te_Staubsaugerbeutel_PM&hash=item566039355f or http://www.ebay.de/itm/Armbandkurzen-Stiftaustreiber-Stiftausdrucker-Werkzeug-/131084177829?pt=Uhrmacherwerkzeug&hash=item1e8539d1a5 or http://www.ebay.de/itm/1x-Stiftaustreiber-Stiftausdrucker-Zange-Uhrenwerkzeug-Uhrmacherwerkzeug-/310765191716?pt=Uhrmacherwerkzeug&hash=item485b0c8224 But I don't think I can adapt them to hold the motors. Any other tricks? 2) The second problem is to drive small wheels with those motors. With the vibration weight attached I can't drive a small foam or cardboard wheel, neither via friction nor a rubber band/belt. I hope it will work once the weight is off. I hope I can solve this issue, else I am stuck with 100 motors that are only suitable for bristle bots ;-) The vibration is strong enoug to move something, also attaching the motors to a cardboard square and directly touch the ground seems to have enough power. I could use a 3d printer to print a gear, but I would like to keep it as simple as possible. Also the groove bearing + shrink tube drive I have seen on another project would not be ideal to build with younger children. I initially was thinking of using bottle caps as wheels and wrap the motor axis with shrink tubing or isolation tape to drive the bottle cap by friction. Thanks for any ideas, advice or suggestions! -Marcus

Advice needed on vibrating motors.? Answered

For a quirky present for a friend I am making a sink plunger seat like this one . Instead of just a saddle I plan to make the seat bigger and in the design of something vaguely saddle/potty-shaped (a veebeam if you are interested, as he worked on them). Anyway for amusement rather than kinky reasons(!) I thought it would be cool to make it vibrate with a remote control. And as I know nothing about vibrating things, my question is does anyone know what I should be searching for? Brand names would be great. It doesn't have to be strong but it needs to be felt through a thick pad of stiff padding/foam and preferably with a separate remote control. Also, is there anything I need to be worried about or such like? Sorry for such a rooky question but I've spent two hours on the internet and all I kind find is how to convert vibrating chairs into XBox chairs and things that are not safe for work(!) Thank you for any help Poppy
