Abstract (en)

[origin: EP1099828A2] The method involves alternately stimulating magnet coils (4A,4B) at a defined frequency starting from a rest state, in which the armature (4D) is held centrally by restoring springs (2A,2B), using an essentially sinusoidal alternating voltage instead of the conventional rectangular wave voltage. The voltage can be either a variable continuous voltage or a variable pulse-width modulated voltage.
