About Motor Control Tools

Motor Control Tools is a free, ad-light reference for engineers working on PMSM and BLDC motor control: calculators, formulas and cheat sheets for motor characterization, current loop tuning, sensing front ends and power stage sizing.

Every calculation runs client-side and is built from a plain, documented formula — no black-box models, no server-side processing of your inputs, and no accounts required. Units are shown next to every value so results stay unambiguous.

The toolkit is under active development. Formulas and calculators are added incrementally, and each one lists the assumptions it relies on so you can judge whether it applies to your motor and drive topology.
