Product overview
The FlashHobby MT3508 is a brushless DC motor with 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. Rotor preparation includes a precision balancing test, while the bearing specification identifies imported NSK/NMB bearings for high-RPM operation. The motor is offered in four specified KV versions—370KV, 415KV, 580KV and 700KV—with custom KV also available, making KV selection part of the procurement configuration.
For mechanical integration, the MT3508 measures 42 x 26.4mm and has a 4.0mm shaft. Its mounting specification is 19*25mm(M3*4), defining the mounting interface alongside the motor’s overall dimensions. The motor cable is specified as 18#AWG with a length of 220mm, providing a concrete cable size and reach for installation planning. Weight is 105.0g including the cables; that inclusion is part of the stated mass and should be retained when allocating component weight.
