Motor EzRun 4278SD 2250kV Sensored 3-6S*

Hobbywing EzRun 4278-2250Kv 3-6S - Sensored Sport Brushless Motor

• Chip built in the motor, when matched with Hobbywing EZRUN MAX8 G2 esc, it not only has perfect compatibility, the ESC can automatically identify the motor and build a pure/full sensor mode power system, providing better manipulating performance and more delicate manipulating feel.
• The rotor adopts four strong magnetic and high temperature resistant sintered Nd-Fe-B magnets, widens the magnetic tile, provides super torque, and makes the motor have strong explosive force and stable output power.
• The independent high-precision encoder always outputs pure rotor position signal, which effectively avoids the interference of sensor signal and makes the motor work stably in sensor state.
• High output efficiency, effectively reduce the motor temperature and output more power under the same load.
• CNC machined aluminum housing, high purity copper windings, advanced rotor structure, 0.2mm silicon steel laminations, high-quality stainless steel output shaft, high-precision bearing for high durability and smoothness.
• The innovative new sensor interface and rubber cover bearing have better waterproof and dust-proof effect than the traditional sensor motor.
