Electric Brushless DC Motor 72V 5000W Peak 8000RPM Heatsink Housing | External Hall, Temperature Sensoring, High Speed Motor for Go Kart Razor Upgrade Kit Motorcycle Scooter

Features

• 5000W Power & Efficient PerformanceExperience high performance with this 72V 5000W brushless motor. It delivers a rated power of 5000W, with a rated speed of 6800 RPM (peak 8000 RPM) and peak torque of 35N.m. Built with pure copper core for superior conductivity, it achieves 90% efficiency for more power and energy savings. (Recommended to use an 80-100A controller for this 5000w motor)
• Upgraded V-Magnet & Smart Temperature ProtectionElectric DC Motor 72V, Features V-Magnet rotor design with 5 high-strength magnet pairs for smoother torque and higher power density. Equipped with KTY84-130 temperature sensor, it allows real-time monitoring and adjustment when paired with programmable controllers (like Fardriver), is designed to extend the 72V motors lifespan.
• Heat sink Housing & IP54 ProtectionFull aluminum body with Class F (155C) insulation, air cooling, it handles high temperatures reliably. IP54 waterproof rating resists dust and water splashes, making this 5000W motor suitable for various outdoor conditions. Offers flexible front/back or bottom mounting options. dont touch the motor when it working ,the to avoid causing harm your body.
• External Hall Sensor Design for Enhanced ReliabilityElectric Go Kart Motor, features external Hall sensor design that places the sensor on the back cover, not inside the motor. This design provides faster heat dissipation, preventing sensor burnouta common failure point in traditional designs. This results in more stable signals, precise control. Important: Do not remove the sensor screws to avoid damage.
• Designed for High-Power Applications & DIY KitsSuitable for high-power applications in a wide range of outdoor equipment. Specifically compatible with: Razor upgrade MX500 MX650 SX500, electric go-karts, dirt bikes, ATVs, mini motorcycles, and scooters. #35 9t sprocket, compatible with #35 chain. This electric dirt bike motormotor requires 72V and a relatively high current to operate stably.

Description

After October 2025, we upgraded the motor's housing, reinforcing the end cover structure and materials. If you need any assistance while using the motor, we will promptly address your needs. Why does my Fardriver controller display a Hall error? The most likely cause is a program mismatch, please let us know to obtain the correct program. Alternatively, the hall wire may not be properly connected. or the Hall may already be damaged, in such case, please let us know for a solution. Why does my 72v 5000w motor turn in the wrong direction and slowly? Check the connection of phase wires. disconnect and connect the self-learning wire repeatedly until the motor rotates normally, after 10 to 20 seconds of rotation, disconnect the self-learning Why did the motor suddenly stop spinning after it started？ Because the motor needs a large output current, your power supply starts its self-protection when it outputs a large current. you can charging the power supply for a few minutes. then can move the protection I received the package, but there seems to be a tiny scratch on the product The scratch may be caused by packaging or transportation, don't affect the performance and service life of the product. if it is too obvious, please tell the us, we will solve it in time Everything is connected, but the motor does not work? Please check your controller and battery specifications to ensure sufficient power and voltage, then verify that all wiring is correct. Finally, you can try the controller's self-learning function, as self-learning can solve most problems. 72V 5000W Brushless Motor 72V 3000W BLDC Motor 72V 5000W Motor Kit 48V 2000W Motor Kit 72V 3000W Motor Kit Electric Twist Throttle 3 Speed Throttle About Doinal Doinal is a professional enterprise that designs, develops, and produces high-quality electronic parts for e bike and moto About Doinal Doinal is a professional enterprise that designs, develops, and produces high-quality electronic parts for e bike and motocycle.
