doinal 72V 3000W no Bracket brushless motor kit Size 3000 72V3000W no Bracket — 6700 RPM, IP67 controller

Powerful brushless 72V 3000W motor kit from doinal for go-karts and scooters that delivers up to 6700 RPM and includes controller, throttle, sprocket, and chain. This complete electrical propulsion package is built for DIYers and small-vehicle builders who want a compact, high-speed brushless motor system with temperature sensing and a waterproof sine-wave controller. Designed to be an upgrade for go-karts, mopeds, and electric motorcycles, the kit combines a pure-copper 72V motor, an 80A-rated controller, and the primary accessories needed for installation so you can increase speed and torque without designing every component from scratch.

How fast and powerful is this motor for a go-kart or scooter?

The motor is rated at 3000W with a nominal speed around 4900 RPM and a top speed up to 6700 RPM under optimal conditions. It uses eight magnet poles and a pure copper stator winding to deliver steady torque and efficient power transfer for small electric vehicles.

• Rated power: 3000W at 72V
• Rated speed: 4900 RPM; max speed: 6700 RPM
• Current draw: 45A typical; supports higher transient currents
• T8F sprocket included for chain drive applications

What protection and monitoring features does the kit include?

The motor incorporates a KTY84-130 temperature sensor that reports thermal status to compatible controllers or apps, helping prevent prolonged overheating. The included Fardriver sine-wave controller is IP67-rated and supports hall-sensor feedback for smoother startup and efficient commutation.

• Motor temperature sensing wired to the controller
• Sine-wave controller with hall-sensor compatibility
• IP67 waterproofing on the controller for outdoor use
• Peak voltage tolerance up to 88V for battery surges

What comes in the kit and how easy is installation?

The package supplies the key mechanical and control components required to convert a vehicle to electric drive: motor, controller, half-twist throttle with display and key, sprocket, and chain. For many hobbyist builds the parts align with common mounting and chain-drive standards, though some fabrication or adaptor plates may be required for unique chassis designs.

• 72V 3000W brushless motor with 6 mm² phase wires
• 80A Fardriver sine-wave controller (hall version)
• Half-twist throttle with voltage display and ignition key
• T8F sprocket and T8F chain for straightforward drivetrain hookup

Which vehicles and riders will benefit most from this kit?

This motor kit fits builders upgrading Razor-style scooters and MX series vehicles, small go-karts, mopeds, and lightweight electric motorcycles that need more speed and stable operation. It suits enthusiasts comfortable with basic wiring, mounting, and chain alignment; professional installation is recommended for high-speed applications.

• Compatible with Razor MX500/MX650/SX500/RSF650 upgrades
• Well-suited for custom go-karts and lightweight electric motorcycles
• Ideal for users who can handle electrical connections and mechanical fitting
• Not intended as a plug-and-play module for all vehicles—may need adapters

Who is this for If you are a DIY builder, small-vehicle fabricator, or hobbyist looking to upgrade acceleration and top-end speed on a light electric vehicle, the doinal 72V 3000W kit offers the core components to achieve that. It balances high power density, thermal sensing, and a waterproof controller in a compact package. Before purchase, verify chassis mounting points, sprocket alignment, and battery compatibility to ensure safe, reliable operation.
