Bode Plot for a three-phase motor

Simulate a three-phase motor live in your browser. This runs the real Bode Plot solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Bode Plot (2nd-Order System)Live

Controls

Presets

A Bode plot shows how a system responds across frequency: gain in decibels on top, phase shift below. This second-order low-pass passes low frequencies and rolls off at −40 dB/decade above its natural frequency. Low damping produces a resonant peak; high damping smooths it away.

Governing equation

Reading this result: Low damping ζ=0.30 produces a sharp +4.8 dB resonant peak just below fn — great for selectivity, but it rings in the time domain.

About this simulation

The full Bode Plot tool models a three-phase 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.

Frequently asked questions

How do I simulate a three-phase motor?
Open this page and use the live Bode Plot tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
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 three-phase motor from your own measurements.
