The design space

What a winding can move.

The envelope comes first: diameter and length put a hard ceiling on continuous torque before any winding decision. Voltage comes second; it decides the Kv the winding has to hit. Everything after that is a trade the brief lets us make for you.

Continuous torque is a thermal number, not a magnetic one: a motor holding 1.1 Nm all day gives three times that for seconds, so a machine that moves in bursts can run a smaller frame.

Lever → what it decides
WindingKv, phase resistance, continuous current
Stack lengthTorque, without touching diameter
Pole countTorque ripple against iron loss
Shaft and flangeThe mechanical interface, to your drawing
FeedbackHall, encoder or sensorless, matched to the drive
Frame diameterThe expensive change; it alters tooling

01Read

An engineer reads the brief exactly as sent. Open questions are normal, not a problem.

02Questioned

Anything unclear comes back as a question, never as an assumption baked into the design.

03Answered

You get a winding proposal and its drawing, built on your numbers.
