GoolRC 2838 4500KV Sensorless Brushless Motor & 35A Brushless ESC for 1/14 1/16 1/18 RC Car

The 4-pole 12-slot hi-torque motor design features a precision-engineered construction for maximum energy conversion. Crafted with high-purity copper windings, it maximizes efficiency, while the CNC-machined 6061 T6 billet aluminum heatsink ensures effective cooling. The motor is equipped with high-RPM ABEC5 oversized bearings and a precision-balanced rotor, ensuring smoothness and reliability at maximum RPM.

Designed for 1/14, 1/16, and 1/18 brushless cars, the motor offers a multi-mounting system compatible with M2.5 screws. Its specifications include a KV rating of 4500 RPM/Volt, a maximum current of 50A, a maximum wattage of 600W, and a maximum voltage of 1.8A. The 4-pole rotor, 0.0285 Ohm resistance, 28mm diameter, and 38mm length contribute to its compact and powerful design.

Accompanying the motor is a high-quality brushless ESC featuring excellent start-up, acceleration, and linearity characteristics. Engineered with the highest-quality components, the ESC ensures efficient and reliable operation. It offers a range of programmable features to suit various chassis, tires, and racing tracks, along with multiple protection functions, including low-voltage cut-off, over-heat protection, and throttle signal loss protection.

The ESC's specifications include a constant current of 35A, a burst current of 120A (10S), and a power supply compatibility of 2-3S LiPo or 4-6S NiMh batteries. The linear mode switch BEC provides a 5V 2A output.

The complete package, including the 2838 4500KV 4P sensorless brushless motor and the 35A brushless ESC, comes in a compact 9.5 × 8 × 6.5 cm (3.8 × 3.2 × 2.6 in) white box, weighing 153 g (5.4 oz). The rotor is also removable and replaceable, allowing for easy maintenance and customization.
