1806 1700KV Brushless Motor 36S DC 1224V Long Shaft 23mm Outer Rotor for DIY Aircraft Tool Model Grinder

Overview

This 1806 1700KV Brushless Motor is a high-speed external rotor motor originally designed for 20V precision polishing tools and has since become popular for DIY aircraft models, electric grinding tools, and creative mechanical projects. With a 3mm D-type long shaft and 23mm rotor diameter, it runs smoothly at high RPM and supports 36S battery input (DC 1224V).

Two base types are available:

• Model A: Base with 2.5mm screw holes (16mm pitch)

• Model B: Base without mounting holes

This 3-phase motor requires an external ESC or brushless driver. At 12V, it reaches ~20500RPM, and up to ~41000RPM at 24V.
