What Is a 370 Brushless Outrunner 1300kv Motor?
A 370 brushless outrunner 1300kv motor is a brushless DC motor designated with a "370" size class (approximately 28mm x 16–20mm stator) and a KV rating of 1300 RPM per volt. This combination delivers high torque at moderate RPM, making it ideal for larger propellers in RC aircraft and multirotor applications.
Understanding the 370 1300kv designation:
- 370 size class – Approximately 28mm stator diameter, commonly used in mid-size RC aircraft and multirotors
- 1300KV rating – 1300 RPM per volt; on 3S (11.1V), spins at approximately 14,430 RPM unloaded
- Outrunner configuration – Rotor on the outside, delivering high torque for direct-drive propellers
- Typical applications – RC airplanes (9–10 inch props), multirotors (8–10 inch props), UAVs

FAQ: 370 1300kv Outrunner Motor Technical Questions
1300KV means the motor spins at 1300 RPM per volt applied with no load. On a 3S LiPo battery (11.1V), a 1300KV motor theoretically spins at approximately 14,430 RPM unloaded. Lower KV motors like 1300KV deliver higher torque and are ideal for larger propellers, RC aircraft, and multirotor applications where thrust, not speed, is the priority. The 370 size class (approximately 28mm stator) combined with 1300KV is a popular choice for mid-size RC aircraft and UAVs.
For 370 1300kv outrunner motors, the optimal stator lamination features: 0.20mm (or 0.15mm for premium) 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 a near-perfect winding factor of 0.933 and low cogging torque—ideal for 1300KV torque-focused operation. High-quality 1300KV outrunner motors use ultra-thin 0.2mm stator laminations for maximum efficiency.
370 1300kv outrunner motors typically use 8–10 inch propellers, depending on the battery and application: (1) 8-inch prop – higher RPM, good for multirotors, (2) 9-inch prop – balanced performance for RC aircraft and multirotors, (3) 10-inch prop – maximum thrust, ideal for heavy-lift and glider applications. Always check the motor's specified maximum current and propeller recommendations before operation.
370 1300kv outrunner motors typically operate on 2S–4S LiPo batteries, depending on the application: (1) 3S LiPo – balanced performance for general RC aircraft and multirotors, (2) 4S LiPo – higher power for heavy-lift and performance applications, (3) 2S LiPo – lower power for lighter aircraft or scale applications. Always check the motor's specified voltage range before selecting a battery.
Epoxy powder coating provides three critical functions for 1300kv outrunner stators: (1) electrical insulation between laminations to minimize eddy currents and prevent interlaminar shorts—critical at moderate RPM with high current, (2) thermal durability up to 180°C (Class H) to withstand the heat generated during sustained high-thrust operation, and (3) corrosion resistance for operation in outdoor RC and FPV environments. The coating thickness (30–60µm) is optimized with dielectric strength exceeding 2.5 kV.
Yes. Reenives supports full customization of 1300kv outrunner stator cores including: stator height (16–20mm), lamination thickness (0.15–0.20mm), 12N14P configuration, stacking height, material grade (35PN210, 35PN250), and epoxy coating specifications.
