Troubleshooting of DC brushless motor control problems

Troubleshooting of DC brushless motor control problems

 

(1) What is the role of the hall line of the brushless motor in its rotation?

 

(2) Can the motor work normally without the hall line of the "brushless motor? If it works properly, what will happen?

 

(3) how to identify and determine whether a brushless motor has a phase of 60 and 120?

 

(4) Factors Affecting the speed of the brushless motor?

 

(5) What is the direct connection between "Speed", "voltage", and "current" of brushless motors?

 

(6) How do I determine the last position (stator) after the motor is powered off )?

 

(7) how to control and implement positive and Reverse Rotation of brushless motors?

 

(8) What are the causes of jitter when the brushless motor starts? How can we try to shake the image as much as possible?

 

(9) How is the noise produced by a brushless motor? How can we minimize noise?

 

(10) When will the motor phase line be short-circuited? How can we avoid short circuits?
