H01F2007/1822 - CPC Classification

Classification description:

Magnets; Electromagnets; Actuators including electromagnets with armatures; Circuit arrangements for obtaining desired operating characteristics, e.g. for slow operation, for sequential energisation of windings, for high-speed energisation of windings; Circuit arrangements for holding the operation of electromagnets or for holding the armature in attracted position with reduced energising current making use of an energy accumulator using a capacitor to produce a boost voltage
