Motor?

Alright i'm converting this old vex system into a rc car and the motor has and idle speed that can be controlled with this small potentiometer and when i turn it so the idle is off when i use it (i use it for steering) and when i use it the idle turns back on and iono what to do any ideas i tried using a resistor but it leaves too little voltage for the motor to turn the steering arm well

Stepper Motor as a 'normal' motor

Hi, I recntly took apart a hard drive and there is a 7200 rpm motor inside. Only problem is that it is a stepper motor and I don't have any equipment to drive stepper motors and buying stuff to do is err... cost prohobititve.  Would connecting a negitive wire to 2 of the terminals and positive(in sort of a crisscross pattern e.g. -+-+) to the other make it run like a regular motor? I just don't want to invest time  to solder it only to have it not work.

Motorized Futon?

I'm not sure if this is the right forum, but I was just tryin' to see if I can find some help for some questions I have.The basic story is soon my brother's moving back into my house, limiting me to one 9x10 room rather than the two I have now. I wanted a futon, but I like building things and creating things, so I thought I'd build my own. Then I thought I could motorize it.The concept is the same concept as the automatic windows on many modern cars. Press the button once, the motor goes until it's at the end, and a relay switches and it stops. Simple enough, right?I'm just not sure which parts to use. I saw this, and thought it'd be enough. I think I did the math and it's something like 150-ish pounds per second [torque](referance: http://www.surplusgizmos.com/Oriental-115v230v-AC-125-HP-Induction-Motor_p_110-1473.html )I'm not sure if that's too strong or not strong enough-- or if it'd even work!Now, I already have the design all set out, I know how I can get the futon to work, and the tracks and everything. For the relay, I was thinking of putting 2 metal plates at each end of the track, attaching the metal plates to springs, so once the motor pushes against it, it hits a relay and shuts the engine off.I'm just not really sure how to do any of this. Not really sure what relays I need or anything like that. Any help would be nice. :D

Motors for Quadcopters

Hi, I am looking to make a quadcopter as my university project and I kinda run in to some problems deciding which motor I need to choose. I was thinking to choose brushless motors as they are more efficient and they give more RPM. HOwever, my professor says that there's no point using brushless/stepper motors as u can get the same RPMs using brushed motors and its the same thing. Hence, can anyone please guide me which motor is best to use and why should I use brushed or brushless motors. I shall be very glad if someone guide me through it. Thank you :)

I am considering motorizing my bike for my work commute. However I don't have enough knowledge about motor output as in torque / rpms to be able to determine what kind of characteristic I should be looking for.

Green Motor

Hey, i am not good at electronics, but heres the idea: i have "planned" an energy saving motor. Anyway there would be a motor, say, driving a bike. The on the wheel's gear we could put another motor, which is for producing electricity. I am not too sure, but i think it produces AC current. But we need DC to drive the first motor (the one moving the bike). So hook up an AC to DC converter to the second motor (the one producing electricity). Then hook some diodes to the wires connecting the first motor from its power source. I think the wires going out from the power source needs diodes, too, since it allows current to flow in one direction (technical term called forward biased? ). To prevent the first motor driving the bike from "burning", a voltage regulator and a current regulator should be needed, right? That's basically the plan. I would be glad to be corrected if i got anything wrong. Thanks.

Slowing a motor

I have a 4 Watt mains powered motor that currently spins at 1.6-1.9RPM. I need to find some way of slowing it to maybe 1 revolution every 10 minutes. It's all sealed in a metal case and connected to the mains by a standard plug. I really need to find a way to do this without breaking it apart stuff as it may need a safety test later, I looked at dimmer switches as they essentially limit the voltage and are a max of 300w. Like this - http://www.jpgelectronics.com/products.asp?partno=350.109 I realise that they are made for lights but it's a similar principle and is only about £6. Would this work? Are there other options if I don't want to break into the motor housing or wiring? Thanks.

Lasers on motors

I am trying to create 8 motorised lasers that move (ideally randomly) between a 135˚ angle. I doubt with my level of knowledge i will be able to make them move randomly but if i can't just moving back and forth between the 135˚ would have to do.These motors would have to be reversable and travel between 2 points making an arc of 135˚, I'm looking at making this in the cheapest way possible. By mounting cheap pen lasers onto mini motors and somehow getting them do this. I will need to see the beams of light so unless i can find a better way to used focused light cheaply, i'll have to use a smoke machine or something. Having no real knowledge of this, would it be easily achievable, i would use a microcontroller to make the motor movement random within that 135 degrees but i have no idea how i'd go about it.

How to build a track with a small electric motor to move something around a circular track?

What is the best way to make a track with powered cars moving around the track? A generator with household voltage will be used to power the track/cars. I know I will need to transform from 120V AC to something else, probably 24V DC from what I have read so far. I don't know much about electricity and the other forces at play in designing such a track, so any detailed information or reference material would be appreciated.
