The factors that affect the operation of dc brushless motor
Brushless DC motor is the abbreviation of Brushless DC execution servo motor; it is a type of synchronous motor, it is means that the rotor speed was effect by the speed of rotating magnetic field of stator and rotor poles (P): n = 60 * f / P . Under the circumstance of the fixed number of poles, the change of the frequency of the stator rotating magnetic field can change the speed of the rotor. Brushless DC motor is that synchronizes motor added to electronic control (drives, including the Ministry of Power and Control Division); Control the frequency of the stator rotating magnetic field and take the rotor speed feedback to the control center to correct repeated, so as to get close the way of DC motor’s characteristics. It means that among certain load, brushless motor can still control the motor rotor to maintain a certain speed when the load changes. Brushless DC micro-motor is one of them.
