TORQUE Issue 01 — Where Torque Meets Thrust brings twelve motors, actuators and thrusters onto one stage: robot-joint actuators, gimbal motors, underwater thrusters and UAV propulsion, every figure traced to official manufacturer data.

In This Issue

  • Editor's Note — Choosing Without Guesswork: why this journal starts from data, not from marketing lines.
  • Editor's Picks — Six Motors Worth a Closer Look: CubeMars AK80-6, AKE90-8 and GL60 II on the actuator and gimbal side; CubeMars DW25, T-Motor U8 Lite and T-Hobby F90 for propulsion in water and air.
  • Spec Comparison — Three U15 Motors for Manned-Class Lift: T-Motor U15 II, U15 XL and U15 XXL on one page, thrust and power read side by side.
  • Application Spotlight — Propulsion for Inspection UAVs: what part-throttle efficiency and position hold demand from a motor.
  • Engineering Note — Rated Torque vs Peak Torque: the most common datasheet misreading in actuator selection, and how to avoid it.
  • Discover ToBMS — Find, Filter and Compare in Four Steps: a worked example of shortlisting a UAV motor on the site.

Every Number, Traced

Each specification printed in this issue comes from the manufacturer's own page or datasheet, is cross-checked against the ToBMS product record, and is re-verified before publication. Where a figure is a peak value with a time limit — 180 s or 60 s — the limit is printed next to the number. Where a manufacturer publishes thrust in grams, the figure appears converted to kilograms-force (kgf) with the source value on file.

Units and Sources

Thrust figures in this issue are printed in kilograms-force (kgf). Where a manufacturer publishes thrust in gram-force (gf), the figure is converted to kgf at 1000 gf = 1 kgf, with the source value kept on file. Torque is printed in Nm and power in watts, with the test window (180 s, 60 s or continuous) stated wherever the manufacturer states one. Every specification was checked against the linked manufacturer publication in September 2026.

About TORQUE

TORQUE is the standing journal of ToBMS — one issue at a time, each with a number and a theme. Issue 01, Where Torque Meets Thrust, puts actuators and propulsion motors on the same bench, because the discipline of reading a datasheet does not change with the application. Every issue stays free to read online and to download as a PDF.
