The DC motors are an integral part of the sealed transmission box. This minimizes any dust or debris entering into the cogwheel gear train.

The motor and its PCB slot into the plastic enclosure, and there are no screws securing the motor.

A small printed circuit board connects to the motor.

The PCB has some SMD capacitors for EMF noise suppression.

The motor shafts have magnets attached to form a magnetic clutch assembly. Since the poles of the magnets always stay aligned, it keeps the motors in synchronisation. This is why this toy is able to travel in a straight line.
