Key Features
- Significantly Improved RPM and Torque Rating — The G3 Stock Spec motor has achieved a 16% improvement in KV rating and a 4% increase in torque compared with the previous generation V10 G2 Stock Spec motor, delivering noticeably stronger acceleration and higher top-end performance for competitive racing.
- High-Precision Hall Sensor Technology — The built-in high precision Hall sensor combined with a perfectly balanced rotor guarantees remarkable linearity of the motor, ensuring smooth, predictable power delivery and consistent performance throughout the entire throttle range for more responsive control.
- Super Lightweight Construction — Weighing just 163 grams (5.75 ounces), the G3 Modified motors are approximately 11% lighter than the previous V10 G2 generation, allowing drivers to easily adjust vehicle balance and centre of gravity for optimised handling characteristics.
- Asymmetric Bearing Design — The front bearing has been increased in size by 26% to improve load-carrying capacity, whilst the rear bearing has been reduced by 6% to minimise resistance and friction, resulting in smoother operation and improved overall efficiency.
- Exceptional Heat Dissipation — The special shell design exposes the stator core to the air, and large-diameter holes on the front and rear end plates maximise cooling efficiency, preventing thermal buildup during extended racing sessions and maintaining consistent performance.
- Stepless Adjustable Mechanical Timing — The mechanical timing can be finely adjusted in smooth increments from 20 to 50 degrees (adjustable), with skid-proof lines on the rear end plate ensuring the timing remains stable after adjustment, allowing precise tuning for different racing conditions.
- Rebuildable Structure — The detachable, modular design allows owners to easily disassemble the motor for regular cleaning, maintenance and component replacement, effectively extending the service life whilst retaining maximum efficiency and performance.
- Interchangeable End Plate Design — The motor ships with end plates featuring large holes for excellent on-road cooling, but owners can optionally purchase and install end plates with small holes to prevent sand and debris ingress for off-road applications.
- Premium Component Quality — High-performance stator core laminations, heat-resistant pure copper wire rated to 200°C, a robust heat-resistant rotor rated to 200°C, international top-brand precision bearings, and copper solder tabs with exceptional current endurance ensure outstanding durability and reliability.
Technical Performance
The Hobbywing XeRun V10 G3 4.5T is a 540-size brushless motor purpose-built for competitive 1/10th and 1/12th scale RC on-road racing in modified class. With a KV rating of 7340 and a 2-pole design, this sensored motor delivers 457 watts of maximum power output and 122 amps at peak power when powered by a 2S LiPo battery. The motor measures 35.9mm in outside diameter with a total length of 51.2mm, featuring a 3.17mm shaft diameter and 13.3mm shaft length for universal compatibility with most modern ESCs and drivetrain components. The no-load current consumption stands at 6.7 amps, indicating excellent efficiency and low heat generation at idle. Internally, the G3 generation features precision-engineered bearings (D9×D4×t4 front bearing, D8×D3×t4 rear bearing) that support the rotor whilst minimising friction. The high-precision, balanced rotor paired with the sensored Hall effect technology ensures consistent, linear power delivery essential for smooth throttle modulation and predictable acceleration during competitive racing. Mechanically adjustable timing from 20 to 50 degrees allows drivers to fine-tune motor characteristics to suit different track conditions, weather, and gearing setups. The robust construction utilising 200°C-rated copper windings and heat-resistant components ensures the motor can handle the sustained high-power demands of competitive racing without degradation. This is a motor designed by racers for racers, incorporating lessons learned from thousands of hours on racing circuits across the world.
