1. Great Durability: The motor uses high purity copper windings and sealed bearings, with built in cooling fans, and an external degaussing sleeve. It has high power, low friction, and low noise. 2. High Efficiency: 55T 550 brushless motors provide accurate and maximum energy conversion. The rotor is accurately balanced and its smoothness improves reliability and maximum speed. 3. Stable Performance: High purity copper windings maximize the efficiency of the 55T 550 brushless motors, and high strength magnets provide stable brush motor performance. 4. Inner Rotor: The inner rotor adopts a multipole winding, which has strong and low speed performance. Ordinary three winding rotor motors have better linearity. 5. Powerful : The armature of the powerful 550 motor is 30% longer than the standard 540 motor, providing extremely high , while high strength magnets ensure optimal performance.
