One engineer's notes on getting motion right.
The independent reference for ultrasonic piezo motion. No vendor affiliation. No sales pitch. Just the physics, the tradeoffs, and what actually works in the field.
01
Fundamentals
The physics of resonant stator actuation, closed-loop control, thermal behaviour, and everything the datasheet doesn't tell you.
02
Technology
Honest cross-technology comparisons. Piezo vs. voice coil, servo, and stepper. Decision frameworks that tell you when NOT to use piezo.
03
Applications
Semiconductor, optics, UAV, and medical device verticals. Specific design problems, specific solutions.
04
Tools
Motor selector, thermal calculator, bandwidth estimator. Built for engineers in active design.
