    Linear motor rules of thumb

    Linear motor rules of thumb

    Sorry for the dalay. Itsmoked, I don't know why, but I never came to think about that. Will check. sreid, yes there are six phases. I chose to make the animation continous, and so it became a bit confusing to watch. I don't understand the part with amplifiers. Turning the windings on and off...

    Linear motor rules of thumb

    Hello all! I have been thinking about making a linear motor. Several permanent magnets on a rail and a trolley with six anchors that is turned on and off in sequence. (sorry if the gif is hogging all resources) I have tried to draw this with a few different measurements. But I can't decide...

    Cogs and shapes

    Thanks a lot! Very informative. Those teeth are made according to the system used in the US only. But the information is indeed very good.

    Cogs and shapes

    The internet is vast and I searched for : cog, cogs, cogwheels, gear, spur, and a few others. Yet another set of Swedish words too. As you may be able to figure out, I came up with nothing. Much to my surprise. Yes I would like to buy the suggested book and more. I bet "Karlebo handbok"...

    I suppose understanding them would aid me in drawing them, which is the goal.

    I am not a machinist, and I want to understand it, as previously stated.

    Qcad saves to dxf, but autocad won't recognise the format. Lisp? I can't say, but I am willing to try. Acad? I'll check it out. Got an address? I tried Google, but found everything but CAD forum. External spur, yes

    Thanks! I appreciate it. It is closer than what I succeded with. Not perfect, but it's a step in the right direction.

    I suppose a professional gearmaker would know far batter than me how to make the teeth. It is not likely though that a pro gets to make these ones. Not even dead certain it is going to be made at all. I guess I want to produce a image of an actual gear by your definition. It is the measurements...
