Application Fields of Brushless DC Motor
How do brushless motors work?
Brushless motors work by alternating the polarity of the windings on the interior of the motor. The magnetic fields created when the coils are generated exert a push/pull force on the permanent magnets arranged around the outside of the casing.
On a brushless DC motor, it is not the motor shaft that rotates, but rather the outside case. Because the central shaft, to which the windings are attached, is stationary, power can be delivered directly to the windings, eliminating the need for brushes.
