Electric motors are the power source in printing equipment. This section provides a brief overview of common faults in DC and AC motors.
Common malfunctions in DC motor operation can be categorized into mechanical and electrical issues. Mechanical faults primarily manifest as bearing overheating, motor vibration, armature-stator core collision, and unusual noise. These are generally caused by armature rotation. During inspection, manually rotate the armature to check for armature-stator contact and determine if the vibration originates from the motor itself or from a faulty transmission mechanism. Vibration due to poor motor self-balancing is less likely; more often, it's caused by poor concentricity of the transmission mechanism. This can damage the motor bearings and even lead to deformation of the armature output shaft.
