DC motor start-up circuit and simulated waveform in PWMSim — This is the editable circuit and completed result in PWMSim. You can review the values, model type, and recommended waveform before opening it.

Try this first

Increase load torque and compare settled current.

The app opens this template, adds the recommended probe, and runs it once. Change the suggested value and run it again to compare the results.

Limits

This example works in the browser, but it is not a promoted LTspice comparison, hardware design, or certification. Check the app for model limits. It does not cover packaging, layout, thermal behavior, or operating conditions that are not listed.
