GEP-GR1408

SUMMARY

GEP-GR1408 motor is GEPRC’s newly developed brushless motor specially designed for 3inch propeller, a highly efficient and powerful motor, incorporating many new features and quality material throughout and is available in three versions - 3500kv, 3750K and 4100Kv to cater to the most demanding of flyers.

The GEP-GR1408 motor features a new streamlined motor shape, offering ultra-low wind resistance for fast forward flight and efficient heat dissipation. Incorporating high performance N52H curved magnets with a stator to magnet air-gap of only 0.15mm, the GEP-GR1408 motor is capable of high torque. High temperature resistance and low current resistant #180 enameled wire stator coil ensures stable power output throughout the throttle range and further enhanced by durable smooth running NSK Japanese bearings. The high precision CNC machined #7075 aluminum shaft increases crash durability of this motors while the large ventilation slots in the bell keeps the motor temperature low.

The GEP-GR1408 motor is optimized for 4S lipo and designed especially for 3inch propellers and when used with the GEPRC 3042 triblade propellers, it provides high output efficient performance. At only 15.2 g, the 4100Kv version generates an amazing 482g. The GEP-GR1408 motor is available in both CCC and CW threaded shaft.

PRODUCT BASIC INFORMATION

 

Features

GR2205 2300KV

GR2205 2300KVGEP-GR2205 2300kv Racer Edition Motor, We studied a lot of flying habits. Motor most of the accelerator will be in the range of 60-90%, So the power of the motor is very important, So we use magnetic N45SH label, SH model with high magnetic loss characteristics, can let the motor to ensure high-speed running off magnetic, protection of electric, magnetic. The appearance design of durable structure, very suitable for racing requirements. Freestyle flight effect also can output power be not of the common sort, make the plane landed at high speed, flexible.
