Feature: 1. 4 Poles Rotor: RC sensorless brushless motor, with 4 poles rotor design, strong torsion and stable output power, low friction, low noise and high accuracy. 2. Good Heat Resistance: High hardness aluminum CNC shell, high temperature resistant copper coil 0.2mm thickness silicon steel sheet, high magnetic permeability, high silicon content, good insulation and heat resistance. 3. High Accuracy: Explosion proof rotor, high toughness stainless steel output shaft, highly precise premium bearings make the motor super durable. 4. Detachable Structure: The detachable structure design is convenient for cleaning and maintenance, effectively prolonging the service life of the motor and improving work efficiency. 5. Temperature Sensor: The motor has a built in temperature sensor and interface, which can be used with the ESC to realize the motor overheat protection function. 6. Waterproof and Dustproof: The ESC is all weather waterproof and dustproof, designed for RC model cars, with excellent starting, acceleration and linearity functions. 7. Strong Current Resistance: For sensorless brushless motor, strong current resistance, excellent heat dissipation, built in switching mode 6.1V 5A or 7.4V 5A (switching mode), compatible with high torsion and high voltage servo. 8. Multiple Protection Features: Low voltage cut off protection for lithium or nickel batteries, ESC overheat protection, motor overheat protection, throttle signal loss protection, motor blocking protection, easy to program and compatible with pocket sized program cards.
