About this part

Hobbywing AXE 540L FOC R2 2800Kv Sensored Brushless Crawler Motor.  

Features:

  • World's First FOC brushless system for Rock Crawler. Field-Oriented Control for Super Linearity & High Torque & Extreme Silence.
  • The chip-type magnetic encoder inside the motor guarantees consistency between three phases’ signals and always outputs the pure and precise signals indicating the rotor position.
  • "POLARITY PROTECTION". Yes it is not a typo. No more "oops" moment. The chip-type magnetic encoder inside the motor guarantees consistency between three phases’ signals and always outputs the pure 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. 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 motor with 4 poles & 12 magnets, featuring Hobbywing’s “staggered pole” patent has zero cogging effect & torque ripple. It can work smoothly at low speeds. This greatly improves the manoeuvrability of rock crawlers at low speeds.
  • The sensor harness, which features the plug-and-screw design, has a silicone O ring inside. The design & O ring not only provide a firm connection between motor and ESC but solve the “waterproof” challenge for sensor ports.

Incredible low end torque and control, especially for a 2800kv motor. I tossed the axe FOC system in my element Trailrunner and it's now faster and slower than ever before. This system has enough power to launch the whole truck off the ground, and the low end to creep slower than I thought possible. I had the first gen axe system, and the R2 is a marked improvement in all categories.
