Motors & Drives
From choosing a motor to tuning the drive, in an order that builds on itself.
Everything on this site about motors, VFDs and motion control, in one place. The pages work as a learning path: pick the motor technology, learn how the drive controls it, shape the motion, add feedback for position, and size and fit the mechanics. You can also jump straight to the page you need. Most pages have a live simulator or calculator, and the numbers agree from page to page.
Click a label to open the page. The drive section covers how the VFD controls the motor and shapes its speed. The motor and feedback section covers which motor and how a position is measured. The mechanics section covers the gearbox, the load and how accurate the whole chain really is.
| Control method | Speed range | Speed regulation | Torque at zero speed | Feedback | Position use |

Typical values. The full comparison, with explorers and a selector, is on VFD Control Methods; the position figures are on Positioning Accuracy & Error Budget.
