Product overview
The FlashHobby MT3515 is a 3515 brushless DC motor built around a 12N14P high-torque design. Its construction combines a CNC-machined 6061-T6 aluminum bell with 48SH-grade magnets and high-temperature-resistant copper-wire winding. The motor also features an imported NSK/NMB bearing described for high-RPM operation, and its rotor features include a precision balancing test. The KV specification is 400KV, with custom KV also offered.
For mechanical integration, the MT3515 measures 42 x 33.4mm and has a 4.0mm shaft. Its mounting specification is 19*25mm(M3*4), defining the mounting dimensions and fastener designation alongside the motor’s overall size. The motor weighs 158.0g including its cables. Those cables are specified as 18#AWG and 220mm long, so the cable-inclusive mass and cable dimensions are both part of the motor’s physical configuration.
