FAQ: 1408 Brushless Motor Technical Questions
A 1408 brushless motor refers to a motor with a stator diameter of 14mm and a stator height of 8mm. The naming convention follows the standard brushless motor designation: the first two digits (14) represent the stator diameter in millimeters, and the last two digits (08) represent the stator height in millimeters. This compact form factor is popular for 3-inch FPV racing drones, micro UAVs, and light-weight drone applications, offering a balance of power and weight.
The optimal KV rating for a 1408 brushless motor depends on the application and battery: (1) 2800–3500KV: High RPM for 3-inch FPV racing on 3S batteries, (2) 2200–2800KV: Efficient micro UAV and Cinewhoop applications on 3S–4S batteries, (3) 2400–3000KV: Sub-250g drones and light-weight applications. For 3-inch FPV racing, higher KV delivers faster acceleration and higher top speed; for Cinewhoop, lower KV provides smoother torque and better efficiency.
For 1408 brushless motors, the optimal stator lamination features: 0.20mm (or 0.15mm for racing) silicon steel, 9N12P or 12N14P slot/pole configurations, burr height < 0.03mm, epoxy coating (30–60µm, Class H 180°C), and stacking factor ≥ 97.5%. For 1408 FPV racing motors, 0.15mm laminations provide ultimate high-RPM performance. For 1408 Cinewhoop and micro UAV motors, 0.20mm laminations deliver the optimal balance of efficiency and cost.
The 1408 and 1407 brushless motors have the same 14mm stator diameter but differ in stator height: 1408 has an 8mm stator height, while 1407 has a 7mm stator height. The 1408 motor (8mm height) offers higher torque and power output than the 1407 (7mm height) due to the additional stator height, which allows for more copper windings. The 1408 is generally preferred for 3-inch FPV racing and heavier 3-inch builds, while the 1407 is better suited for ultra-light 3-inch and 2.5-inch builds.
Epoxy powder coating provides three critical functions for 1408 brushless motor stators: (1) electrical insulation between laminations to minimize eddy currents and prevent interlaminar shorts, (2) thermal durability up to 180°C (Class H) to withstand the heat generated during high-power 1408 motor operation, and (3) corrosion resistance for operation in outdoor and humid environments. The coating thickness (30–60µm) is optimized for tight slot geometries with dielectric strength exceeding 2.5 kV.
1408 brushless motors are used in: 3-inch FPV racing drones (high KV, aggressive flight), Micro UAVs / Cinewhoop (smooth flight, efficiency), Sub-250g drones (weight reduction, compliance), Light-weight camera platforms (stable flight, vibration reduction), Indoor / Tiny FPV (responsive control, safety), and Micro UAV surveying (long flight time, stable hover).
