Details

The M5 steel shaft is designed to fit most propellers, while the included nut helps protect the shaft threads.

High-precision bearings, 220°C copper wire, and 0.2 mm silicon steel laminations support efficient operation.

The BAT B3214 is available in 730KV, 800KV, and 1000KV versions for 7–10 inch FPV drone builds.

A detachable construction provides access for cleaning, and front air outlets aid heat dissipation.

48SH NdFeB rotor magnets and a lightweight hollow-core steel shaft form the motor’s rotating assembly.

Refer to the test data and dimensional drawing when selecting the KV option for the intended propeller and build.
