- (1) Manual
FEATURES:
- EzRun MAX 4200 Series G2R Motors have excellent compatibility with the Hobbywing EZRUN MAX8 G2S ESC. The ESC can automatically recognize this motor, creating a fully sensored power system that offers improved control performance and a refined control feel, while also enabling motor overheat protection.
- The rotor features four high-strength, high-temperature-resistant sintered Nd-Fe-B magnets with widened magnetic tiles, delivering exceptional torque, expLosive power, and stable output.
- An independent magnetic ring ensures that the Hall sensor consistently outputs a pure rotor position signal, effectively avoiding sensor signal interference and enabling stable operation in sensor mode.
- With high output efficiency, this motor reduces temperature and delivers more power under the same load.
- Its CNC-machined aluminum housing, high-purity copper windings, advanced rotor structure, 0.2mm silicon steel laminations, high-quality stainless steel output shaft, and high-precision bearings enhance durability and smoothness.
- The innovative new sensor interface and rubber-covered bearings provide superior waterproofing and dustproofing compared to traditional sensored motors.
