RC Car Newset 2838 3800KV Brushless Motor & 45A Waterproof ESC

The Jrelecs 3930KV 4P Sensorless Brushless Motor and the Jrelecs All Waterproof 45A Brushless ESC are a powerful combination designed for RC car enthusiasts. Let's dive into the detailed specifications of these components:

Motor Specifications: Brand: Jrelecs KV (RPM/Volt): 3800KV Max Current: 57A Max Watts: 800W Max Voltage: - IO: 2.2A Rotor Poles: 4 Resistance: 0.0213 Diameter: 28mm Length: 38mm Shaft Length: 15mm Shaft Diameter: 3.175mm Weight: 116g Sensored: No

The motor features a 4-pole, 12-slot high-torque design, with high-purity copper windings that maximize efficiency. The CNC-machined 6061 T6 billet aluminum heatsink can, combined with high-RPM ABEC5 oversized bearings, ensures precision engineering for maximum energy conversion. The short stator and low resistance winding contribute to higher power output. Additionally, the precision-balanced rotor provides smooth operation and maximum RPM, making it suitable for 1/14, 1/16, and 1/18 brushless car applications with a multi-mounting system for M2.5 screws.

Electronic Speed Controller (ESC) Specifications: Constant Current: 45A Burst Current: 240A Power Supply: 2-3S LiPo Battery / 4-9S NiMh/Ni-Cd BEC Output: 5.8V / 3A Power Supply Plug: T Plug Male Size: 52 * 39 * 39mm / 2.0 * 1.5 * 1.5inch

Features of the Waterproof ESC: 1. Water-proof and dust-proof for all-weather races. (Note: Please uninstall the cooling fan before using this ESC in water, and clean and dry it soon after use to avoid corrosion of the connectors.) 2. Specially designed for RC cars with excellent start-up, acceleration, and linearity features. 3. Compatible with sensorless brushless motors. 4. Strong resistant current capability and excellent heat dissipation. 5. Multiple protection features: Low voltage cut-off protection for lithium or nickel battery, over-heat protection, throttle signal loss protection, and motor blocked protection. 6. Easily programmed and compatible with a pocket-sized program card.

The package includes: 1 * Jrelecs 3930KV 4P Sensorless Brushless Motor 1 * Jrelecs All Waterproof 45A Brushless ESC

In conclusion, the Jrelecs 3930KV 4P Sensorless Brushless Motor and the Jrelecs All Waterproof 45A Brushless ESC are a high-performance, durable, and versatile combination suitable for a wide range of RC car applications. Their advanced features and specifications make them an excellent choice for enthusiasts seeking a reliable and efficient power system.
