    Modelling DC motors in Mathcad?

    Thanks for the info guys, But referring to PNachtweys post, The problem of the model in the link, is that it assumes *moment of inertia of the rotor (J) = 0.01 kg.m^2/s^2 * damping ratio of the mechanical system (b) = 0.1 Nms * electromotive force constant (K=Ke=Kt) = 0.01 Nm/Amp * electric...

    Modelling DC motors in Mathcad?

    So, how feasible/possible/acceptable is it? Modelling it with a series resistor (for wire resistance) then a series inductance then another series resistance, then finally a capacitor and resistor in parallel). Measuring (and obtaining) typical stall and run currents (at a voltage). Also...

    How to assign a "symbolic result too large to display" to a function?

    Hi, I'm trying to calculate inverse laplaces of functions (Circuits) and simply having two different energy storage elements (such as indcutors or capacitors, can't think of the term right now) in certain configurations causes mathcad to say that the result is too large to display but that I...

    Remove all hard Page Breaks

    Is it possible to remoev all hard page Breaks (the ones that you can insert) of a mathCAD file? I have some Collapsed "Areas" there as well, so is there a way to avoid affecting them but removing all inserted page breaks? Hello! I'm the new guy.

    Equation Substitute?

    Thanks guys.. Greg, the substitute function works if you have only one level deep equations, like my example above.. What if the A(x) equation was A(x):= G(x)+5 And so on.. with equations that refer to equations that refer to other equations (poor choice of words, sorry). If the equation...

    Equation Substitute?

    If we had the following in a mathcad worksheet: ~~~ A(x):= 3x+5 B(y):= 4y-3 C(z):=z+1 D(x,y):=45+A(x)+B(y)+C(3) ~~~ Is it possible to use a substitute command on D(x,y) that easily (or automatically) returns all the equations that D(x,y) is referring to and populates them into D such as...
