How do I simulate a DC motor?

Open this page and use the live Sampling & Aliasing 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.

Sample rate (Hz)

To capture a signal faithfully you must sample above twice its highest frequency — the Nyquist rate. Sample too slowly and a high frequency masquerades as a lower one: aliasing. Push the signal frequency above half the sample rate and watch the reconstructed wave collapse to a false, slower tone.

Nyquist frequency10.0 Hz

Statusproperly sampled

Apparent frequency3.0 Hz

Governing equation

f_{app} = f - f_{s} round (\frac{f}{f _{s}}) = 3.0 Hz, f_{N} = \frac{f _{s}}{2} = 10.0 Hz

Reading this result: Sampling at 20 Hz puts the Nyquist limit at 10.0 Hz. The 3 Hz signal sits below that, so it is captured faithfully and reconstructs at its true frequency.

About this simulation

The full Sampling & Aliasing tool models a DC motor with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
