Why are motors so expensive?

    I need a couple of low power electric motors for my project so i went on farnell and found them all to be around €30 which is ridiculous, I'd be better off smashing open RC cars to get motors. Does anyone know where I can get cheap generic electric motors?

    Why don't you try your local model shop.
    Thanks Adam

    All my local model shop stocks is kits without motors. The hardware shop is no help either.

    less than 20 volts preferably, thanks I thought vcr motors were full on 240 v motors which wouldn't work with with my school project. (I'm using an atx power supply).

    The small motors inside most electronic equipment usually run of low voltages (in the range you want).

    Often you can puck up electronic equipment that has been thrown out and get parts for nix.

    Keep away from things like microwave ovens, blenders, etc., but keep an eye out for VCRs, CD/DVD players, printers, etc.

    I've had some really punchy 12 volts motors from old cordless drills and car tyre inflators.

    Are we talking brushless? Yes brushless motors are
    very high. For most uses you don't need brushless. Brushed 3-24v range in 3$ to 30$ on amazon.

    Yeah I dismantled an old floppy drive (with a hammer) and got the motor. Microwaves are actually good to dismantle for their flybacks.

    Try looking on fleabay. I found some REALLY nice motors with planery gearboxes for £8 from China. Delivery was about 2 weeks, but they are great.
    Look at this link
    Geared motors
