Hobbywing XeRun Xerun 4274 SD G3 2250KV Sensored Brushless Motor for 1/8 RC Monster Truck

Overview

This Motor is the Hobbywing XeRun Xerun 4274 SD G3 2250KV sensored brushless motor, designed for 1/8 scale RC competition applications including Monster Truck and Touring Car setups. It supports a pure signal sensor mode circuit for full-sensored operation when paired with Hobbywing XeRun XR8 series ESCs.

Key Features

• Turbo Timing Technology (when paired with Hobbywing XeRun XR8 series ESCs).
• Full-sensored mode (when paired with XR8 ESC); built-in integrated circuit helps the ESC identify the sensor unit for Pure Sensored operation.
• Mechanical turbo timing adjustable in both directions (CW/CCW) from 20-40.
• Turbo feature note: when G3 series motors are paired with XR8 Pro G2 ESC, the turbo feature can be set to a maximum of 48.
• Advanced Hall sensor system (error-free Hall sensing system) with a separate magnetic ring intended to keep Hall sensor location output clean and reduce external interference effects.
• Low cogging.
• 4-pole, 8-magnet Staggered Pole rotor (patented design).
• Dustproof design rated IP5X for 4274-2250KV (note: only 4268-1900KV/2200KV and 4274-2250KV are IP5X).
• Efficiency statement: compared with XERUN 4268/4274 G2, structure is optimized and efficiency is improved by 6% or more, reducing temperature increase (reducing thermal runaway).
• Construction highlights: single-piece 7075 aluminum bar CNC-processed stator case; silicone O-ring seal at the sensor port/sensor base; gold-plated U-shaped/90 curved copper solder tabs with low internal resistance.
• Materials: double insulated windings (240C R-rated), high-intensity adhesive (340C), NMB bearings (Japan).

Details

The XeRun sensored brushless motor is designed for 1/8-scale RC builds and pairs with a full-sensored power system for smoother control.

Hobbywings 1/8 power system supports Turbo Timing technology when paired with compatible XeRun XR8 series ESCs.

The XeRun sensored brushless motor features an adjustable mechanical turbo timing ring with CW/CCW markings from 20 to 40 for precise setup.

XeRun SD G3 motors feature a finned can design and A/B/C solder tabs, with the manufacturer noting improved efficiency to help reduce temperature rise.

The G3 motors Hall sensor system uses a separate magnetic ring to help deliver a clean, accurate rotor position signal.

The XeRun SD G3 off-road motor features an IP5X dustproof design to help minimize debris entering the motor.

The XeRun 4268SD G3 sensored motor uses a finned aluminum can and lightweight design to help keep your 1/8 RC setup balanced.

The Hobbywing XeRun sensored brushless motor features a finned aluminum housing and is labeled 1900KV, with low cogging effect noted on the graphic.

The sensored motor uses gold-plated U-shaped solder tabs for A/B/C phase wiring and a silicone O-ring seal at the sensor port.

The XeRun 4274 is listed as a single 2250KV option for 1/8 off-road use, alongside 4268 on-road and off-road KV variants.
