The brushless DC motor is a type of synchronous motor, that is, the speed of the motor rotor is affected by the speed of the rotating magnetic field of the motor stator and the number of rotor poles (P): n = 60 * f / P. When the number of rotor poles is fixed, changing the frequency of the stator's rotating magnetic field can change the speed of the rotor. DC brushless motor is a synchronous motor with electronic control (driver), which controls the frequency of the stator's rotating magnetic field and feedbacks the speed of the motor rotor to the control center for repeated corrections in order to achieve a way close to the characteristics of DC motors. In other words, the brushless DC motor can control the motor rotor to maintain a certain speed when the load changes within the rated load range.China Dual Inlet Centrifugal Fan Suppliers
