Product overview
The DYS SF2207 is a motor component for propeller-driven propulsion, with 1750KV, 2450KV and 2750KV configurations. Integration choices depend on the selected motor variant and its battery–propeller pairing. The 1750KV configuration has operating points for 7×4E, 6040×2 and 5045×2 propellers; the 2450KV configuration covers 5045×2 and 6040×2, while the 2750KV configuration covers 5045×2.
Four-cell LiPo combinations use 16 V, and five-cell combinations use 20 V. At 1750KV with a four-cell LiPo and 7×4E propeller, one operating point pairs 1080 g pull with 22.7 A and 363.2 W. At 2450KV with a five-cell LiPo and 6040×2 propeller, another pairs 1620 g pull with 33.2 A and 664.2 W. These configuration-dependent figures describe individual motor operation.
