GoolRC 3650 4370KV 4P Sensorless Brushless Motor and 45A Brushless ESC for 1/10 RC Off-Road Car

The 4-pole brushless motor design features a high-torque configuration, with a CNC-machined 6061 T6 billet aluminum heatsink can to optimize cooling. The use of high-purity copper windings maximizes the motor's efficiency. Oversized ABEC5 high-RPM bearings ensure smooth and reliable operation, while the precision-balanced rotor provides optimal smoothness and maximum RPM capabilities.

The stator features super-thin 0.35mm laminations, which are removable and replaceable for easy maintenance. The motor has been precision-engineered to maximize energy conversion, making it ROAR (Remotely Operated Auto Racing) legal.

Featuring a 4370KV rating, the motor can handle a maximum current of 66A and a maximum power output of 820W. With a can size of 3650, the motor has a diameter of 36mm and a length of 50mm, with a 3.175mm shaft diameter and a 15mm shaft length. It utilizes a 4mm bullet connector.

Weighing in at 146g (5.2oz), the motor is compatible with 2S to 3S LiPo or 4-9 cell NiMH battery packs, with a maximum voltage of 7.4V (2S) to 11.1V (3S).

The accompanying brushless electronic speed controller (ESC) is designed for seamless compatibility with sensorless brushless motors. It boasts high anti-interference capabilities and utilizes an advanced software interface, allowing for easy setup and firmware updates.

The ESC's throttle linearity is super-smooth and accurate, with a fast response to input. It incorporates multiple protection features, including low-voltage cutoff, overheating protection, and throttle signal loss protection, ensuring reliable and safe operation.

The ESC can handle a continuous current of 45A and a burst current of 260A for up to 10 seconds. It supports 2-3 cell LiPo or 4-9 cell NiMH battery packs and features a built-in SBEC (Switch-Mode Battery Eliminator Circuit) that provides a 5.8V/3A power supply. The ESC measures 45mm x 35mm x 35mm (without the fan) and weighs 76g (2.7oz).

The complete package includes the 4370KV brushless motor and the 45A brushless ESC, packaged in a compact box measuring 11cm x 9cm x 6.5cm (4.3in x 3.5in x 2.5in) and weighing 261g (9.2oz).
