Brushless DC Motor Application and Operation
Brushless DC Motor is a type of electric motor which relies on a electronic controlled commutation. Conventional DC motors use a commutator in contact with a brush set to make the electrical contact which forms the electric current to the field coils windings.
Brushless DC motors use an electronic controller which regulates and controls the voltage and current to the field coils. The electronic module or controller uses discrete devices and amplifiers to establish and deliver the desired voltage/current. Advantages of a brushless motor include, increased reliability, longer life, elimination of sparks from the commutator, reduced friction, precision voltage/current applied to the field coils, faster rate of voltage and current.
Brushless dc motors using a electronic controller require a motor position sensor for the electronics to precisely determine and apply the correct signal timing. Some motors utilize a hall effect sensor to establish the position of the rotor relative to the field coils.
