Brushless DC motor itself is the electromechanical energy conversion part, it in addition to the motor armature, permanent magnet excitation two parts, but also with a sensor. The motor itself is the core of brushless DC motor, which not only relates to performance index, noise and vibration, reliability and service life, but also involves manufacturing cost and product cost.

Advantages of 57mm square bldc motor:
A BLDC motor with three coils on the stator will have six electrical wires (two to each coil) extending from these coils. In most implementations three of these wires will be connected internally, with the three remaining wires extending from the motor body (in contrast to the two wires extending from the brushed motor described earlier). Wiring in the BLDC motor case is more complicated than simply connecting the power cell’s positive and negative terminals; we will look more closely at how these motors work in the second session of this series. Below, we conclude by looking at the advantages of by BLDC motors.
Applications of high quanlity brushless dc motor:
We can expect to see BLDC motors used in a wider range of applications in the future. For example, they will probably be widely used to drive service robots—small robots that deliver services in fields other than manufacturing. One might think that stepper motors would be more suitable in this type of application, where pulses could be used to precisely control positioning. But BLDC motors are better suited to controlling the force. And with a stepper motor, holding the position of a structure such as a robot arm would require a relatively large and continuous current. With a BLDC motor, all that would be required is a current proportionate to the external force—allowing for more power-efficient control. BLDC motors may also be replacing simple brushed dc motors in golf carts and mobility carts. In addition to their better efficiency, BLDC motors can also deliver more precise control—which in turn can further extend battery life.
BLDC motors are also ideal for drones. Their ability to deliver precision control makes them especially suited for multirotor drones, where the drone’s attitude is controlled by precisely controlling the rotational speed of each rotor.
How does Brushless DC motor work? The need of a drive circuit explained.
Making an electric motor rotate requires that the direction of current flow through the motor windings (coils) is alternated in order to generate a rotating magnetic field. In the case of brushed DC motors, this is achieved through the mechanical action of brushes and commutator. Then how do brushless DC motors, which don’t have these parts, generate the rotating magnetic field and turn?
Instead of a commutator and brushes, brushless DC motors use semiconductor switches. Brushless DC motors generally have three coils, with semiconductor switches connected to each of these. Turning the semiconductor switches on and off in the correct sequence alternates the current flow, which generates the rotating magnetic field that causes the motor to turn. Accordingly, the motors require a drive circuit to perform this sequencing. Furthermore, the semiconductor switches are switched by detecting the orientation of the permanent magnet rotor, using a magnetic sensor (typically a hall sensor).
