DC Motor

Hi Guys, I have a 15.6 volt dc motor taken out of a handheld vacuum cleaner. is this suitable to use in a small wind generator as a project with my kids. when i attach it to a power drill and spin it from the shaft i dont seem to get any power generation. If i connect it to a 12v battery is spins real fast. any help would be appreciated sam

I've been wanting to teach myself more about mechanics, and I want to work on a rebuild project. There are problems though: my workshop is small, I don't have a shop-crane, and there's not a lot of money to put into it. I was wondering If there are any motors that are just like that of a car's that are small, cheap, and readily available. I've taken apart a few two- and four- stroke engines, nothing more than a lawnmower. I want to self-educate myself more. Thanks.

Suggestions for small motors for an art project?

Howdy Folks, I'm doing an art piece that will require many small motors and know nothing about them or even where to start looking. What I'm thinking is something similar to a clock that will spin 3-4 roundish cast paper layers (one nests inside the other) on the same axis but at different speeds and maybe different directions. Initially I had thought about using small battery operated clocks but I need something with more options. Each layer will be lightweight (made of paper) and the speeds will be relatively slow. Since I may need about 30 of them I'd prefer them to be inexpensive. And, since I'm new to this area of knowledge I need them to be relatively simple. Grateful for any suggestions! Thank you in advance. Cheers.

How can I sequence several small motors. Answered

Wife approved Home Theater ​I plan to build raised panel cabinets that also hide home theater speakers and 60" screen. Open display/bookshelves sit between the speaker garage and the 60" screen. The raised panel (I'll make with my 5hp shaper) covering the speaker will roll over the display cabinet allowing the speakers to move out into the room on motorized platforms. Then, the speakers will rotate on a motorized turntable  to the desired position. Next, the two panels covering the screen will move under the speaker panels and also cover the display cabinet plus a little of the garage space. I want this to all be initiated with the push of a button. The motors will all be sequential in the above order. First, the speaker panel can roll until it hits a button, next, the speaker platform movement could be controlled by motor revolutions as in a stepmotor and would stop the platform at the right spot. When this action is complete, the speaker rotation could also use a step motor count. Next, the two screen panels will roll under the speaker panels until they hit a final stop button. I will need a central controller to manage the sequence order. I am familiar with Fishertechnik robotics controllers but I'm hoping that someone here can give me some suggestions to make this work. Thanks for reading. Chuck

Small electric motor to power something along a track?

I want to build a circular track and power a pretty light cart along the track... doesn't have to be fast... only 2-3 mph. I need a way to power it. I thought first of making a center pole with an extension cord coming out, but as the cart continues in circle, the cord would twist and twist then knot. I then thought I could power the wheels with a car batter(ies). However, I don't know the first thing about how long a charged battery would be able to power a light motor, etc. I don't know the first things about electricity, so any help or reference material would be appreciated. Is there a better way to do this? A rotating plug on the pole, for example? Simple diagrams to show how? Thank you so much!

How to attach a small motor to a piece of wood?

I am not so sure this is possible, but I have a small 8rpm motor that I would like to attach to a piece of wood. The trick is I want to attach is so the wood is hanging under the motor, so I need a way to permanently attach it so that it will still spin, but not drop a 3lb-ish load. I don't know much about all this, so if you need anymore information from me about the parts just ask. Thanks! EDIT: The motor is a small dc motor. It's about an inch and a half long cylinder. The spinning part is on the end of the cylinder, a bit off center, and is shaped like a partial cylinder. I hope this explaination makes sense.

Charging NiMh batteries using a small motor - Help!!

I want to build a battery charger that is capable of charging 12v (2x6v) of NI-Mh PCB type batteries (varta packs from farnell) . I think the batteries are button types bound together. The input will be from a small 1" diameter motor spun to give 12v out (I assume this is a dynamo). The output from the batteries needs to power : a 12v wireless reciever (6mA standby/66mA switching) a 12v - 24v dc/dc converter powering a solenoid at 25mA@24v. I have seen a 12v charge regulator in Maplins but it is designed for car batteries. If I send the 12v motor/dynamo output to the charge controller and then onto the batteries will they blow up? As I am a mechanical engineer this is new to me so can anyone help ?
