The stator is a stationary part of the motor that contains the winding coils. The rotor is a rotating part of the motor that contains the magnets. The gears are used to transfer the rotational force from the motor to the load.

The motor operates by using DC power to create a magnetic field in the stator winding coils. This magnetic field interacts with the magnetic field of the rotor magnets to create a rotational force. The rotational force is transferred to the gear train, which converts the rotational force into linear force. The linear force is used to move the load.

Compared with brushed dc gear motors, the advantages of brushless dc gear motors include high efficiency, long life, low noise, and low maintenance. The disadvantages of BLDC gear motors include high cost and the need for a controller to operate the motor.
