A DC motor trades torque for speed along a straight line. See where a given load lands you, and where the motor delivers the most power.
DC Motor Torque–SpeedLive
where torque meets power
Controls
Presets
A DC motor trades torque for speed along a straight line: maximum torque at stall, maximum speed at no load. Mechanical power (torque × speed) peaks right in the middle, at half the no-load speed. Educational tool.

How it works
An ideal DC motor follows a linear torque–speed line: maximum torque at stall, maximum speed at no load. Because power is torque times speed, mechanical output peaks at half the no-load speed — the sweet spot for sizing a motor to its load. Educational tool.

Is this dc motor torque speed curve tool really free?▾
Yes. DC Motor Torque–Speed runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?▾
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?▾
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?▾
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
