What's New in AC Motors
2.4.1
October 21, 2026
Safer calculations. The calculator now opens empty and never fills in values for you: frequency, poles, connection, parallel circuits and wire quantity must be entered or picked before you can calculate. After a nameplate scan, anything the photo did not show stays empty, a checklist shows what is still missing, and "Use these values" waits until the plate's key values are filled. New tips help you take a sharper photo.
