The BLDC brushless DC motor overcomes the conge nital defects of the brushed DC motor and replaces the mechanical commutator with an electronic commutator.bldc motor controller .

Therefore, the brushless DC motor not only has the characteristics of good speed regulation performance of the DC motor, but also has the advantages of simple structure, no commutation spark, reliable operation and easy maintenance of the AC motor.

The essence of the brushless DC motor is the input of the DC power supply, and the electronic inverter is used to convert the DC power to the AC power. The three-phase AC permanent magnet synchronous motor with rotor position feedback.
