A squeal phenomenon in an electromagnetic clutch depends not only on time-independent factors (shape and size, natural frequencies and damping ratios of a rotor and an armature) but also on variable factors (a contact region and a contact position). In this paper, the stability of a two-disk system modeled after a practical clutch is discussed theoretically. Numerical calculations based on this squeal theory show the influence of a contact region and a contact position on the squeal : (1) the fourth mode squeal is generated when an armature is in contact with the outer pole of a rotor ; (2) the lower mode squeal is generated when the armature is in contact with the outer part of the facing surface of the rotor ; (3) no squeal is generated when the armature is in contact with the entire facing surface or with the inner pole of the rotor.
