Hobbywing XeRun AXE540 1200KV Brushless Sensored FOC Motor

The AXE540 motors has not only a new FOC sensor design, but also compared to other crawler design motors an improved staggered pole rotor design. What does that mean? It transfers to smoother operation with no cogging and a very clean and consistent de-acceleration. It also means smoother brakes, smoother power and the transitions between them are improved. This is specific needs for the trail and crawling market and allows for extremely precise throttle control under any load conditions.

Features:

• The first FOC (Field-oriented Control) brushless power system for rock crawlers will provide the very powerful low rpm torque compared to standard sensored brushless and brushed power systems. This also translates to higher efficiency and longer runtimes. The chip-type magnetic encoder inside the motor guarantees consistency between three phases’ signals and always outputs the pur e and precise signals indicating the rotor position.
• The waterproof and dust-proof design (*IP67 standards) allows the AXE brushless power system to be used in all weather & track conditions without any issue of damage caused to the system from water or dust. But damage to the vehicle caused by water, mud, or conditions should be monitored closely when running in muddy, wet, or adverse conditions. Intelligent torque output & speed closed-loop control for easy control, and consistent motor RPM under all loads.
• The adjustable drag brake & drag brake rate control with the maximum drag brake of up to 200% (that’ s nearly twice the drag brake of standard brushless power systems can provide) unprecedented parking capacity on slopes, with no jerky stops.
• The motor has 4 poles & 12 magnets, featuring Hobbywing’s patented “staggered pole” delivers zero cogging effect & torque ripple. It can work smoothly at low speeds. This greatly improves the maneuverability of rock crawlers at low speeds.
• The new sensor harness, which features the plug-and-screw design, has a silicone O-ring inside. The new design & O-ring not only provide firm connection between motor and ESC but solves the “waterproof” challenge for the sensor ports.
