Hobbywing EzRun 4990SD G2 1650kV Sensored Brushless 3-8S Motor Features: Upgraded to a sensored system, with better accelerate linearity and stronger explosive force. It has perfect compatibility when it is matched with Hobbywing EZRUN MAX6 G2 / EZRUN MAX5 HV G2 esc, the esc can automatically recognize this motor, and build a power system with full sensor mode, providing better control performance and more delicate control feel, and also realizing the motor overheat protection function. The independent high-precision encoder always outputs pure rotor position signal, which effectively avoids the interference of sensor signal and makes the motor work stably in sensor state. CNC machined aluminum housing, high purity copper windings, high strength explosion-proof rotor, ultra thin silicon steel laminations, high-quality stainless steel output shaft, high-precision bearing for high durability and smoothness. The innovative new sensor interface has better waterproof and dust-proof effect than the traditional sensor motor. 8S Sensored motor - Power on Demand The EzRun 4990/5690SD G2 motor is known to be dynamic and dominant. The motor supports up to 8S LiPo and are built to meet the needs of various demands on the market. The motor us powerful and has great response and a linear feel at low speeds to allow the vehicle to easily perform various maneuvers. Great control and plenty of power for hard launches, straight line speed and jumps! Perfect match for EzRun MAX6 G2 ESC The EzRun 4990/5690 SD G2 motor is the perfect match for the EzRun Max 6 G2 ESC. The sensored combo provides excellent control, and power that is easy to drive. Overheating protection for both the motor and the ESC are an added layer of safety. Remarks: After replacing the 8mm plug, it is also compatible with MAX5-G2 ESC. Wider Adaptability The EzRun 4990/5690 SD G2 has 6.5mm bullet plugs pre-installed, and also includes an extra set of 8 mm bullet plugs for usage with ESC's that also have 8mm motor plugs, like the Max5 G2. . All weather sensor plug system The EzRun 4990/5690 is equipped with the HOBBYWING all weather sensor harness that makes all conditions, water proof, sensored combos a reality. This proven sensor harness keeps the elements out so your system can maintain fully sensored operation even in the worst conditions. Note: The IP67 protection level mentioned above is splash-proof, water-proof, and dust-proof under normal use, but it is not permanently effective, and the protection performance may decline due to daily wear and aging. Do not soak in water for a long time, otherwise the product may be damaged. High efficiency - Low temperature rise The motor has ultra-high efficiency, resulting in extremely low temperature rise when comparing it with a motor of the same specification. Using a 0.8N m load test, the internal temperature is 25°C lower, and the outer temperature is 9°C lower. Module design for easy maintenance The motor adopts a modular structure design, which is convenient for daily cleaning and maintenance, effectively prolonging the service life of the motor and maintaining the working efficiency of the motor.
