Introduction:
An electric motor has a stator and a rotor. Both are electrically/magnetically induced to produce magnetic fields either through current fed coils or permanent magnets. The combination of repulsive and attractive magnetic fields across stator and rotor help the motor to convert fed-electrical power into rotational mechanical energy. In the traditional DC motors, the electrical energy is fed to the rotor (two power the copper coils) via a conducting carbon brush, which is pressed on to the metal leads on the rotor.
The drawback of brush-based motors is they produce electric-sparks resulting in electromagnetic noise and also requires maintenance. The electronic systems such as computers and such electro magnetic noise (EMI) sensitive devices are susceptible to noise produced by brushed motors.
Brushless DC (BLDC) Motor operates with a controller via electronic communication. BLDC motors rely on a combination of sensors, magnets, and electronic devices to switch winding current. The electronics devices together does the same function as mechanical commutators used on standard DC motors, but without physical contact and hence they are frictionless, clean with no carbon dust, quiet in terms of electrical noise and maintenance free.
So BLDC motors need semiconductor ICs. Here in this article we provide you with list of some latest ICs for your brushless DC motor control circuit design. Before selecting the IC if you need some education on how brushless DC motor works, please refer to the links below.
