Hobbywing XeRun V10 G4R Motor - ROAR Edition

Powerful and efficient.
New Stator, Rotor, and Sensor Assembly improves the G4R spec motors overall performance and power dramatically.

Faster and more powerful, the G4R platform shows confirmed improvements in overall speed and power output by up to 5%.

Comparing it with the V10 G4 motor series, the output power is increased by nearly 4%.

The new Hobbywing G4R 13.5 shows 7% more speed and 9% more power, under the same test loads, as popular non Hobbywing motors.

Low internal resistance, high efficiency
The new G4R stator and winding design reduces the overall internal resistance while maintaining the requirements for sanctioning spec class rules. The improved motor efficiency reduces the temperature rise to keep internal resistance numbers consistent.

The internal resistance is about lower than that of G4

Good heat dissipation with low temperature rise

The motor adopts an open core can, and uses an all new Rotor. This allow the heat generated by the stator to be directly cooled by airflow. The can and rotor design allows air flow through the motor to maximize cooling.

Dual version selection
The standard version is designed according to IFMAR/EFRA rules. and the ROAR version is designed according to ROAR rules.

The ROAR version uses thermally conductive winding epoxy to fill the coil caps and increase overall heat dissipation. Lower temperature rise and improved overall performance.

The temperature of the ROAR version is about 15% lower for the same input power.

Note: The standard version is in the EFRA list, and the IFMAR list is pending certification; the ROAR version is in the ROAR certification list, and the specific version used is subject to the rules announced by the competition.

Wear-resistant silent gasket
Updated nylon mixed shims provide ultra quiet motor operation and provide long lasting consistency. The wear resistance of the gasket is increased by approximately x2 times

220℃ high temperature resistant enameled wire
G4R motor windings use the highest temperature rated wiring to date. This allows further resistance to heat, while increasing the overall motor efficiency. Compared to other brands, temperature resistance is up to 40 degrees celsius higher. Resistance to high temperature damage means the motor can be pushed to it's limits and come back for more.

Dual sensor port
The G4R features dual sensor ports providing racers with options for sensor wire routing. The unused port is protected by the included silicon port plug.

Optional rotor available
The motor comes standard with a rotor (PN 30820450). It is suitable for most Blinky competition applications; the optional rotor (PN 30820407) has a stronger magnetized rotor and is suitable for medium and large track (Blinky) competitions, or high traction tracks application.

Easy Maintenance
The G4R uses a sleek and simple modular design. This makes regular service and cleaning simple and direct. Cleaner motors last longer and run more efficiently.

Industry-leading materials and excellent product design
The copper on the motor is 50% thicker to ensure lower internal resistance and greater heat capacity of the motor. The large opening heat dissipation structure at the tail of the motor provides an excellent heat dissipation effect for the sensor components.

Specifications:
Excellent performance, specially designed for 1/10 -1/12 STOCK racing. Designed to pair with HOBBYWING XR10 Stock Spec G2 ESC
The innovative outer diameter structure of fully exposed stator core maximizes the heat dissipation area and the rear end of the motor is a big opening structure to further improve the heat dissipation effect.
Dual sensor interface design to meet various wiring/layout requirements.
The special copper bar is customized and the spacing of copper bar is widened, which greatly facilitates the operation of soldering wire.
The built-in high precision Hall sensor combined with the high precision and balanced rotor guarantee outstanding linearity of the motor.
The use of high-performance stator core, 220°C high-temperature-resistant enameled wire, high precision and high strength bearings, and copper solder tabs with super current endurance guarantees outstanding
