FAQ: 700KV 3508 BLDC Motor Technical Questions
A 700KV 3508 BLDC motor has a stator diameter of 35mm, a stator height of 8mm, and a KV rating of 700 RPM per volt. This combination delivers exceptional torque and thrust for heavy-lift drones, hexacopters, octocopters, and UAV applications. The 3508 designation indicates the stator size, which determines the motor's power output and torque characteristics. The 700KV rating makes it ideal for 13–15 inch propellers on 4S–6S battery systems.
For 700KV 3508 BLDC motors, the optimal stator lamination features: 0.20mm silicon steel, 12N14P slot/pole configuration, burr height < 0.03mm, epoxy coating (30–60µm, Class H 180°C), and stacking factor ≥ 97.5%. The 12N14P configuration delivers smooth torque and reliable performance for heavy-lift applications. With optimized stator design, 3508 700KV motors can achieve 85–90% efficiency.
The optimal propeller for a 700KV 3508 BLDC motor depends on the battery and application: (1) 13–14 inch propellers on 4S–6S for hexacopter and general heavy-lift applications, (2) 14–15 inch propellers on 4S–6S for octocopter and maximum payload applications, (3) 13 inch propellers on 6S for high-efficiency setups. Always check the motor's specified maximum current before selecting a propeller.
700KV 3508 BLDC motors typically operate on 4S–6S LiPo batteries: (1) 4S – balanced performance for general heavy-lift applications, (2) 5S – increased power for heavier payloads, (3) 6S – maximum thrust and performance for heavy-lift octocopters and professional UAVs. Always check the motor's specified voltage range and maximum current before selecting a battery.
Epoxy powder coating provides three critical functions for 3508 700KV 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 sustained heavy-lift operation, and (3) corrosion resistance for operation in outdoor and agricultural environments. The coating thickness (30–60µm) is optimized with dielectric strength exceeding 2.5 kV.
700KV 3508 BLDC motors are used in: hexacopter UAV platforms (6-motor setups), octocopter UAV platforms (8-motor setups), heavy-lift professional drones, agricultural UAVs, surveying and mapping drones, and industrial inspection drones. The 3508 700KV combination is a trusted workhorse for heavy-lift applications where exceptional thrust and reliability are essential.
