Product overview
The GEPRC GEP-GR1507 Motor is designed for 3-inch and 4-inch models and operates with 2~4S LiPo batteries. Its construction combines a high-precision CNC-machined body with a lightweight base and an Al 7075 base casing. The stator measures 15mm in diameter and 7mm in length, while the hollow shaft has a 2mm diameter. N52H arc magnets form the rotor, with a 0.15mm air gap, and Japanese NSK bearings support smooth motor operation.
Airflow heat dissipation and a dedicated heat-radiation structure form part of the motor’s cooling design. The body is precisely dynamically balanced to support low vibration and low noise during high-speed operation. Its construction also incorporates 24AWG wire. Together, the machined aluminum structure, arc magnets, bearing arrangement and cooling features provide the mechanical and thermal design of the GEP-GR1507 for its intended 3-inch and 4-inch model applications.
