Hobbywing - Brushless Motor Ezrun 4000Kv

Great for use in off road trucks and Truggy's, The EzRun 3660-G2 is a great sensorless brushless motor upgrade.

• Innovative 4-pole-8-magnet "staggered pole" rotor (Hobbywing-patented) with low cogging effect and torque pulsation greatly improves control feel around corners.
• Built-in temperature sensor and sensor port protect the motor from damage due to overheat when pairing EZRUN 3660 G2 with a EZRUN MAX10 SCT ESC.
• O-ring seal fitted between the front end bell and motor case isolates screw holes from inner parts to prevent liquid or dust from getting inside and protect motor from damage.
• Special design implemented by the motor case (the end attaches to the front end bell) isolates inner coils from outside to protect winding from being damaged by overlong screws.
• Special technology for temperature control implemented by this motor guarantees less heat more efficiency (efficiency rate of up to 90%).
• CNC machined aluminum housing, high purity copper windings, advanced rotor structure, high-quality alloy steel output shaft, high-precision bearings for high durability and smoothness.
• Rebuild-able design (partially rebuild-able) for routine maintenance effectively prolongs the motor life and raises the motor efficiency.
• Excellent match between EZRUN 3660 G2 with EZRUN MAX10 SCT guarantees users large torque plus a very smooth and linear power band.
