Arrangement of laminations on a rotor or armature to provide a slight angular pattern of their slots with respect to the shaft axis. This pattern helps to eliminate low speed cogging effects in an armature and minimize induced vibration in a rotor as well as reduce associated noise. Also can help to increase starting torque.

Arrangement of laminations on a rotor or armature to provide a slight diagonal pattern of their slots with respect to the shaft axis. This pattern helps to eliminate low speed cogging effects in an armature, minimizes induced vibration in a rotor, and minimizes harmonic stray currents.

Slight rotation of an image relative to the original document, usually caused by imperfect alignment of the page in the scanner’s document feeder.

The laminations arranged on a rotor or armature. These help abolish low-speed cogging effects in an armature and reduce induced vibration in a rotor.

Rotation of a bar code symbol about an axis parallel to the symbol's length.
