In this paper, the generation of squeal noise in electromagnetic friction clutches or brakes is explained by the energy which flows from a frictional surface into a disk. If an infinitesimal change of the bending moment caused by a frictional force effects positive work on the disk during a cycle, the energy flows into a disk and squeal is generated. When the thickness of the stationary disk is greater than that of the stationary disk, the waves of the self-excitation. The linear component of the spring characteristic on a contact surface is related to self-excitation. The positive work performed by the linear component is converted into the additional kinetic energy of the increased vibration. The work performed by the nonlinear component is always negative, and it dissipates the kinetic energy of the disk.
