Product overview
The BrotherHobby Nipple 3525 530KV/570KV/610KV/640KV Motor is a propulsion component in the fixed-wing motor range. Its physical construction combines a 25mm stator, a SUS420 shaft and a rotor using N52H arc magnets. Both the base casing and bell cap use Al 7075, and the motor configuration is 12N14P. The specified weight is 237g. These details define a motor for integration into an aircraft propulsion installation, rather than a complete flight platform or an airframe kit.
Installation interfaces comprise an M3 bolt pattern of 25X25mm and an M4 pattern of 46.4-50X46.4-50mm, with 16# AWG wiring supplied at 100mm length. The bearings are specified as Φ14*Φ8*4, and the battery specification is 6-8S LiPo. The named motor variants are 530KV, 570KV, 610KV and 640KV; the KV selection also includes 890. That additional selection is distinct from the four variants in the model name and detailed KV specification.
