How what is the distinguishing feature of brushless gear motor controller

Gear brushless motor controller possesses many characteristics, such as the following: 1. Compact structure, small volume, and withstand overload capacity is strong. 2. Wide selection, speed spectrum width, and transmission ratio fine classification. 3. When using low energy consumption, good performance, little vibration, low noise. 4. Strong commonality, easy maintenance, and low maintenance costs. 5. Strong adaptability to the environment, can work in harsh environments, such as corrosion, moisture. From what has been discussed above, we know about the characteristics of the gear brushless motor controller?
