ARRIS Brushless Motor is jointly developed by Hobby-Wing and the most professional motor manufacturer in China. This professional motor has 2 series: multirotor motors and brushless gimbal motors. We pursue the highest quality from material to processing technology to ensure the outstanding quality of every ARRIS motor.
The advantage of ARRIS Motors is as follows:

1. Motor Spindle: ARRIS motor adopts authentic Japan Kawasaki 20JNE1200 material. With this, the motor becomes more efficient and gets lower temperature during flight.
2. Magnet: NdFeb N45UH high heat resistance magnet, with nickel plating on the surface. (T-Motor also use the NdFeb N45UH magnet)
3. Varnished Wire: ARRIS Motor adopts 155 degree high heat resistance vanished wires
4. Bearings: ARRIS 5010 adopts authentic EZO bearing
5. Dynamic Balance: We ensure every ARRIS Motor has been processed by dynamic balance. And the balance quality can reach in 0.01 left/right. (This is the extremity of the balancing machine at present)
