An electronically commutated DC motor without brushes is referred to as a Brushless DC Motors, BLDC motor, or BL motor. The synchronous motor's speed and torque are controlled by the controller by sending short bursts of current to the motor windings. These motors are very effective at generating a lot of torque across a wide speed range. Permanent magnets move around a fixed armature in brushless motors, which solves the issue of connecting current to the armature. Electronics-based transportation offers a wide range of possibilities and adaptability. They are renowned for their quiet operation and ability to maintain torque at rest. In essence, there are two types of Brushless DC Motors: outer rotor motors and inner rotor motors. Only the design of the two is fundamentally different; otherwise, their operating principles are same.
