Candidate matches by voltage class, standard power step and duty; the footprint badge means the candidate fits within the source drive envelope (width and height, ±2 mm, from official dimension tables) — always confirm control features, I/O, and dimensions against the datasheets before substituting.

Enter nameplate values (or photograph the plate). We size on continuous current (FLA × service factor × duty margin), then list matching VFDs — authorized brands first.
Motor sizing FAQ
- What do I read on the nameplate?
- Look for horsepower (HP) or kilowatts (kW), full-load amps (FLA or rated current), supply voltage, and service factor (SF). FLA is the most reliable gate for drive current — use it when it is printed.
- Why does service factor matter?
- SF is how much continuous overload the motor can deliver (often 1.15). The drive must cover motor power × SF × application margin, not nameplate HP alone.
- When should I call instead?
- Multi-motor buses, regenerative loads, long motor cables, extreme ambient temperature, or crane duty with unusual overload cycles — call 877-727-8757 for application engineering. This tool returns candidates, not a certified selection.
