450W 36V Brushed DC Motor Kit

This kit supplies a 450W brushed DC motor rated for 36V operation alongside a matching speed controller and twistgrip throttle. It is intended for builders converting go-karts, e-bikes, scooters or similar light electric vehicles. The package includes the motor with flywheel, chain, custom sprocket, mounting hardware and a fuse kit for a complete installation.

78% Efficiency 70 dB Thermal Profile

The motor runs at 78% conversion efficiency, limiting waste heat during normal riding. Acoustic output is specified at 70 dB under load. Rated speed is 3000 RPM before the 7.18:1 reduction, giving 410 RPM after deceleration, while no-load speed reaches 4000 RPM or 560 RPM after gearing. Rated torque of 1.43 N·m supports steady climbing on moderate inclines.

100 kg Load 117x112x129 mm Footprint

The assembly weighs 8.9 lbs (4.02 kg) and measures 117 x 112 x 129 mm, fitting many standard motor mounts. It accepts a maximum rider and cargo weight of 220.5 lbs (100 kg). The kit provides mounting plates, rubber pads, fixing plates and M6×45 bolts for secure attachment. CW rotation must match the drivetrain layout of the host vehicle.

Questions about this item

How do I mount the 117 x 112 x 129 mm motor and controller kit on a go-kart frame, and what step is often missed?

Bolt the mounting plate to the frame using the M6*45 bolts, align the 7.18:1 sprocket with the rear axle chainring, fit the chain and tension it, then wire the twistgrip throttle to the controller — the step most people skip is securing the fuse kit inline on the positive lead before first power-up.

Which parts of this 450 W brushed motor kit will wear out and need replacement after extended use?

The carbon brushes inside the 100 % copper core motor, the drive chain and custom sprocket, and the twistgrip throttle potentiometer are the items that typically require replacement as they accumulate hours.

At what point does the 36 V motor hit its thermal or current limit during a long climb with a 100 kg load?

The controller will cut power when the motor approaches its 450 W continuous rating or when winding temperature rises enough to trigger the built-in protection, which typically occurs first on sustained steep grades at the 1.43 N·m rated torque.
