Product overview
The YAHREE JT8110 is a propulsion motor for professional multi-rotor aircraft used in surveying, inspection, mapping and precision flight. Its 95 KV configuration combines a 36-slot, 42-pole layout with an 81 mm outside-diameter, 10 mm-high stator using Kawasaki 20JNEH1200 silicon steel laminations. The shaft end cap, base and front bell use anodized, CNC-machined AL7075-T6 aluminum. SUS303 locating pins support component alignment, while an included anodized AL6061-T6(SS) waterproof cover provides protection against moisture and dust.
Integration requires space for an 87.1 +/-0.1 mm diameter and 28.05 +/-0.3 mm length. Recommended equipment comprises a 12S–14S LiPo battery, a 12S / 80 A ESC and a 28–29 inch propeller. At 48 V, continuous limits are 45 A and 2160 W; the 60 A and 2880 W maximum is limited to 15 seconds. Thrust depends on propeller, voltage and test conditions. Weight is specified as 280 +/-8 g, with 290 g also listed separately. Custom KV, appearance and color options are available for OEM/ODM projects.
