The speed of a brushless DC motor is related to the frequency applied to the coil, provided that the motor is powered by multiphase pulses;
If it is a brushless motor such as a stepper motor, its speed is related to the error signal received by the brushless DC motor, and its speed is directly proportional to the error signal;
The formula for calculating the speed of a brushless DC motor can also determine that its speed is related to the point voltage, armature resistance, and air gap main magnetic flux;
If the motor voltage is constant, the speed of a DC brushless motor is affected by factors such as magnetic flux and the number of turns in the coil;
In addition, the speed of brushless DC motors is also affected by factors such as voltage, coefficient of motor structure, and magnetic induction intensity.
What factors affect the speed of a brushless DC motor depends on the specific situation.
