Brushless DC motors usually use rotor magnets with tile type magnets. Trapezoidal air gaps can be obtained after magnetic circuit design. The stator windings use concentrated full-range windings, so the induced back-EMF is trapezoidal.The control of the brushless DC motor needs position information feedback, and it must have a position sensor or a position sensorless estimation technique to constitute a self-controlled speed control system.During the control, each phase current is also controlled as a square wave as much as possible, and the inverter output voltage can be controlled according to the brushed DC motor PWM method.In essence, the brushless DC motor is also a kind of permanent magnet synchronous motor, and the speed regulation actually belongs to the category of variable voltage and variable frequency speed control.

A permanent magnet brushless DC motor is a DC motor that establishes a magnetic field from one or more permanent magnets. Its performance is similar to that of a forced excitation DC motor with a constant excitation current, which can be easily adjusted by changing the armature voltage. Compared with the other-type DC motor, it has the advantages of small size, high efficiency, simple structure, and low copper consumption. It is the main type of low-power DC motor.
