Brushless DC motors, or BLDC motors, are a type of motor that utilizes a DC electric power supply. A primary benefit of BLDC motors is that they are commutated electronically rather than using brushes like in standard electronic motors. These brushes can wear down quickly, so by eliminating them, BLDC motors reduce maintenance costs, improve efficiency, and offer high durability.
A BLDC motor works similarly to a brushed DC motor. Their operation is based on the Lorentz force law, which states that when a conductor and a current are placed in a magnetic field, force is generated. Due to this reaction, the magnet will experience an equal and opposite force.
BLDC motors have two main parts: a stator and a rotor. The rotor is made up of permanent magnets, and the stator contains coils that generate a magnetic field when an electric current passes through them. When any stator coil, or pole, is energized, the rotor aligns its constant magnetic field to it; in simpler terms, the rotor will be attracted to it. The permanent magnets on the rotor are spun by alternating the direction of the magnetic field generated by the motor windings.
BLDC motors are long-lasting, energy-efficient, and reliable. Other key advantages of BLDC motors include:
Due to their many benefits, BLDC motors are commonly used in a wide range of applications, including but not limited to:
