Abstract

To control the current flowing in at least one electromagnet, to regulate a low impact speed of an armature on a pole face, method involves detecting the armature path (s) and the time curve of the armature velocity (v). These values are compared with performance characteristics stored in the controller for the relationship between speed and path to determine reference values f controlling the current in the electromagnet. The actual current value is compared with the reference current value and the difference is used to control the current is supplied to the electromagnet.
