CyberGear Micromotor: Original 24 V, 7.75:1, 317 g catalog entry; not a newer or different CyberGear revision. ## Engineering scope & sources ### CyberGear Micromotor / efficiency **Revision scope:** Original CyberGear, 24 V / 7.75:1 / 317 g; not CyberGear 2.0 No complete bus-to-output efficiency map established in the reviewed original manual; its torque–speed curve is not efficiency. **Scope / unknowns:** Iq/phase current and bus voltage do not substitute for synchronized bus-power and output-torque measurements; regeneration and idle losses remain unknown. - [Chinese manual (mirror)](https://roboticscv.com/wp-content/uploads/pdf/CyberGear%E5%BE%AE%E7%94%B5%E6%9C%BA%E4%BD%BF%E7%94%A8%E8%AF%B4%E6%98%8E%E4%B9%A6.pdf): PDF pp4,6,15–16; parameter/telemetry tables; reviewed pp1–30 ### CyberGear Micromotor / thermal **Revision scope:** Original CyberGear, 24 V / 7.75:1 / 317 g; not CyberGear 2.0 Vendor overload table includes 11 N·m/45 s, 10/60, 9/90, 7/320 at 24 rpm, 25 °C ambient and 120 °C winding endpoint. **Scope / unknowns:** 120 °C is not a protection setting: board ceiling 80 °C, CAN default motor warning/fault 75/80 °C. Initial winding temperature, mounting/airflow, NTC-to-winding offset and repeat-cycle recovery are unknown; no cooldown inferred. - [Chinese manual (mirror)](https://roboticscv.com/wp-content/uploads/pdf/CyberGear%E5%BE%AE%E7%94%B5%E6%9C%BA%E4%BD%BF%E7%94%A8%E8%AF%B4%E6%98%8E%E4%B9%A6.pdf): PDF pp4–5 section 1.3.15 overload table; p6 board limit; p24 section 4.1.10 CAN defaults ### CyberGear Micromotor / precision **Revision scope:** Original CyberGear, 24 V / 7.75:1 / 317 g; not CyberGear 2.0 14-bit single-turn sensing and reported load-side position do not establish loaded accuracy, mechanical play or bidirectional repeatability. **Scope / unknowns:** Independent external-reference loaded metrology was not established in these reviewed sources; resolution is not accuracy. - [Chinese manual (mirror)](https://roboticscv.com/wp-content/uploads/pdf/CyberGear%E5%BE%AE%E7%94%B5%E6%9C%BA%E4%BD%BF%E7%94%A8%E8%AF%B4%E6%98%8E%E4%B9%A6.pdf): PDF pp6,10,15–16,25; encoder and position feedback tables ### CyberGear Micromotor / modeling **Revision scope:** Original CyberGear, 24 V / 7.75:1 / 317 g; not CyberGear 2.0 Author-reported exploratory MuJoCo identification fits friction/inertia, then manually retunes inertia after a 10 Hz mismatch, worsening step-response agreement. **Scope / unknowns:** Not peer-reviewed or a portable calibrated model: torque scaling assumed, revision unpinned, raw data and held-out load/temperature errors unavailable. Record AppCodeVersion/AppGitVersion and actual gains; CAN reads 0x7019–0x701D require unspecified newer firmware and are not debugger-only extended telemetry. Type18 writes are power-off volatile. - [hossyan exploratory identification](https://zenn.dev/hossyan/articles/2406675c7d76a3): Sections 2.1–2.3/results/high-frequency validation; manual inertia retuning - [Chinese manual (mirror)](https://roboticscv.com/wp-content/uploads/pdf/CyberGear%E5%BE%AE%E7%94%B5%E6%9C%BA%E4%BD%BF%E7%94%A8%E8%AF%B4%E6%98%8E%E4%B9%A6.pdf): PDF p13 identity; pp14–16 debugger fields; pp24–25 volatile writes/conditional CAN reads ## Arithmetic from catalog values Differences are subtraction of retained catalog values, not measured advantages.
