Brushless DC Motors
Brushless DC Motors Confused about motors? Understand the principle and applications of these high efficiency motors. What is a Brushless DC Motor? A Brushless DC Motor (BLDC) is a brushless motor which is powered by a direct current voltage supply. In conventional DC motors, brushes are used to transfer the power to the rotor as they turn in a fixed magnetic field, while the brushless DC motors are commutated electronically, thereby eliminating the use of brushes. BLDC motors are broadly used in various applications owing to their high efficiency and exceptional controllability. It also has power-saving advantages as compared to other types of motor. Construction of BLDC Motors In a BLDC motor, the mechanical commutator used in the conventional DC motor is replaced with an electric switch circuit. A brushless DC Motor is basically a type of synchronous motor. Therefore, the magnetic field generated by the stator and the rotor revolve at the same fre...
