Abstract
A method for controlling an electromagnetic brake () having a coil carrier (), a solenoid (), an armature disc (), and at least one further force-exerting element. The internal and external poles () of the coil carrier each have a front surface with a varying gradient that fits, in a complementary fashion, the front surfaces of the respective internal and external poles () of the armature disc. The brake has an air gap () which varies in size and forms a stroke region (). When excitation occurs, the solenoid generates a magnetic force, and the force-exerting element generates an opposing force, wherein the ratio of the solenoid's magnetic force and the opposing force varies at least once between greater than and smaller than one during the movement of the armature disc in the stroke region owing to the variation of the excitation of the solenoid.
