Motors & Actuators
Superseded — see The Plant: Actuators, Encoders & IMUs
The motor theory — the two-pole DC plant, back-EMF/torque-constant derivation, brushless commutation, encoder and IMU interfaces, and the electrical-vs-mechanical pole separation that governs loop design — has moved to The Plant: Actuators, Encoders & IMUs. This note now serves only as a curated link library for motor vendors, driver ICs, build logs, and open-source ESC projects. The split is deliberate: theory notes should stay clean enough to re-read, and a 175-line resource dump does not re-read well.[fn:: The pattern is borrowed from how a reference handbook separates the "how it works" chapter from the "where to buy one" appendix. A learning note that mixes derivation with a link to a $12 H-bridge gate driver is signalling that it was written by someone who never came back to it.]
