Selection and application guide
Choosing the right configuration
Match supply, ESC and propeller to the voltage range, winding KV, rated current and maximum current. Keep data for each KV separate; peak test points do not establish continuous output.
Installation and integration
Check the outline, mounting holes and screw length. Check rotation safely with the propeller removed. To reverse rotation, isolate power, confirm safe discharge and swap any two phase leads.
Operation and maintenance
Increase load gradually and monitor current, temperature rise, vibration and fasteners. Stop for abnormal noise, heat or binding. Store at -10 to 50 °C and no more than 85% relative humidity.
Structure and connection reference
Geometry follows the source. Verify the actual model and approved drawing before installation.
