Tips: BLDC Motor Working Principle

BLDC motor works on the principle similar to that of a conventional DC motor. According to the Lorentz force law which states that whenever a current carrying conductor placed in a magnetic field it experiences a force. In case BLDC motor, the current carrying conductor is stationary while the permanent magnet moves.

When the stator coils are electrically switched by a supply source, it becomes electromagnet and starts producing the uniform field in the air gap. Due to the force of interaction between electromagnet stator and permanent magnet rotor, the rotor continues to rotate.

Motor produces torque because of the development of attraction forces and repulsion forces. By this way motor moves in a clockwise direction. Based on this signal from sensor, the controller decides particular coils to energize. Hall-effect sensors generate low and high level signals whenever rotor poles pass near to it. These signals determine the position of the shaft.
