Product Description

Quanly Outer rotor brushless motors use a compact design with an external rotor that provides smooth, stable rotation. These motors are capable of achieving higher torque than its counterpart inner rotor designs. The higher inertia produced by external rotor motors makes them ideal for applications that require lower noise and reliable performance at high speeds

• Working voltage:20-50.4V
• Speeds up to 15624rpm
• Maximum output power up to 6700W
• High-power density
• Heat sink cooling fins
