Hobbywing XeRun 2848SD Sensored Brushless Motor
Don't let the compact size fool you. The XeRun 2848SD packs serious performance into a 28.5×48mm frame — 15% more power output than motors of equal size, IP5X dustproof, and cogging so low it's about 1/4 of popular competing brands. Built for 1/14 and 1/12 scale heavy-duty trucks and on/off-road applications where smooth low-speed control and durability matter.
Key Features
- 15% More Power Output – Compared to motors of equal size and specifications — more punch without upsizing your motor
- IP5X Dustproof – Sealed for dusty off-road track environments, keeping internals clean run after run
- 6% Higher Efficiency, Lower Running Temperature – 0.1 N·m load test results: max efficiency up 6%, internal temp ~20°C lower, external temp ~10°C lower vs comparable motors
- Ultra-Low Cogging – Approximately 1/4 the cogging of popular brands for smooth, linear throttle response at low speeds — ideal for crawling and technical driving
- Full Sensored Mode – Pairs with Hobbywing XeRun XR14 ESC for pure sensored operation and precise throttle control
- Adjustable Mechanical Timing – CW/CCW rotation; adjustable 20–40° for power tuning
- Modular Design – Easy to disassemble, clean, and maintain in the field
- Premium Materials – Iron core, high-precision grade bearings, 200°C heat-resistant wire, 180°C heat-resistant rotor, gold-plated U-shaped copper solder bars with widened gap for easier soldering
