- 5000W Power & Efficient PerformanceExperience high performance with this 72V 5000W brushless DC motor. It delivers a rated power of 5000W and peak power of 10KW, 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, longer range, and energy savings. (Recommended to use an 80-100A controller for this 5000w motor)
- Upgraded V-Magnet & Smart Temperature ProtectionFeatures 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/Kelly). This system prevents overheating, ensuring safer operation and extending the motors lifespan.
- Heat sink Housing & IP54 ProtectionEngineered for endurance with integrated aluminum heatsink housing, air cooling that dissipates heat rapidly during intense use. Encased in lightweight, full aluminum body with Class F (155C) insulation, it handles high temperatures reliably. IP54 waterproof rating resists dust and water splashes, making it suitable for various outdoor conditions. Offers flexible front/back or bottom mounting options.
- External Hall Sensor Design for Enhanced ReliabilityFeatures 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, and superior long-term reliability. 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 kits, electric go-karts, dirt bikes, ATVs, mini motorcycles, and scooters. #35 9t sprocket, compatible with #35 chain. For optimal performance, we recommend pairing it with 80-100A programmable controllers (we have 72V 5000W motor kit in our store).

Great motor. Easy hook up with thick cable wire and a solid platform to mount. Make sure you pay attention to the sprocket and I would recommend getting a few different sprocket sizes that fit your set up. Also yes plenty of power but careful of any display/controller set up you use. This motor capable of a lot of amps and a lot of times the esc/display set up will only let small amounts of amps through making this motor feel weak and underpowered. Lots of amps it needs.

It’s a nice motor I’m sure for sure if you mount it properly from the bottom but I put this on a razor mx650 frame and took it off road and the motor cracked not to mention the motor wires got so hot they almost caused my controller to catch fire
