DYS Sun Fun SF2207 Brushless Motor

The DYS Sun Fun SF2207 is a 2207 brushless motor for 5-inch freestyle and racing drones, offered here in 2450KV and 2600KV. It runs on 4S or 5S LiPo, mounts on the standard 16 × 16 mm M3 pattern and has an M5 threaded prop shaft.

Key features

• 2207 stator sized for 5-inch propellers.

• M5 threaded shaft takes standard 5-inch props with a prop nut.

• 16 × 16 mm M3 base fits most 5-inch frame arms.

• 20AWG motor wires, 15 cm long.

Bench data — 2450KV

• 4S, 5045 two-blade: 900 g at 19.53 A, peak 964 g at 21.34 A (341.4 W)

• 4S, 6040 two-blade: 900 g at 16.81 A, peak 1250 g at 26.5 A (424 W)

• 5S, 5045 two-blade: 900 g at 16.8 A, peak 1318 g at 28.1 A (562.2 W)

• 5S, 6040 two-blade: 900 g at 14.1 A, peak 1620 g at 33.2 A (664.2 W)

Peak draw reaches about 33 A on 5S, so a 35 A or larger ESC suits this motor. DYS's dimension drawing and test tables for the SF2207 range are below; there is no published table for the 2600KV winding, which sits between the 2450KV and 2750KV figures.
