How do I simulate a DC motor?

Open this page and use the live Active Filter (Bode) tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a DC motor from your own measurements.

Cutoff fc (Hz)

Filter order

A filter passes some frequencies and blocks others. The cutoff fc = 1/(2πRC) is where the response falls 3 dB; beyond it the magnitude rolls off at 20 dB per decade per order — steeper filters cut harder. Educational tool.

Governing equation

∣ H (f) ∣ = \frac{1}{1 + ( f /1000 ) ^{4}}

Reading this result: The −3 dB cutoff sits at 1.0 kHz, where the low-pass response begins to roll off. Order 2 sets the steepness at 40 dB/decade — a gentle slope that eases into the stopband with minimal ringing. Raising the order steepens the roll-off while adding phase lag around the cutoff.
