    Advantages of BLDC Motors

    • 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.
    • One big advantage is efficiency, as these motors can control continuously at maximum rotational force (torque). Brushed motors, in contrast, reach maximum torque at only certain points in the rotation. For a brushed motor to deliver the same torque as a brushless model, it would need to use larger magnets. This is why even small BLDC motors can deliver considerable power.
    • The second big advantage—related to the first—is controllability. BLDC motors can be controlled, using feedback mechanisms, to delivery precisely the desired torque and rotation speed. Precision control in turn reduces energy consumption and heat generation, and—in cases where motors are battery powered—lengthens the battery life.
    • BLDC motors also offer high durability and low electric noise generation, thanks to the lack of brushes. With brushed motors, the brushes and commutator wear down as a result of continuous moving contact, and also produce sparks where contact is made. Electrical noise, in particular, is the result of the strong sparks that tend to occur at the areas where the brushes pass over the gaps in the commutator. This is why BLDC motors are often considered preferable in applications where it is important to avoid electrical noise.

    The main parameters to be referenced in the selection of brushless DC motor are as follows:

    • Maximum torque: this can be obtained by adding the load torque, moment of inertia and friction. In addition, additional factors such as air gap air resistance influence the maximum torque.
    • Square modulus torque: can be approximately considered as the continuous output torque required for practical application, determined by many factors: maximum torque, load torque, moment of inertia, acceleration, deceleration, and running time, etc.
    • Speed: this is the required speed, which can be determined according to the speed trapezoidal curve of the motor, usually 10% margin should be left in the calculation.
