<p>The solenoid has a cylindrical coil with improved coil effect at reduced power consumption. The coil has an armature with a non-magnetic guide cylinder, which carries the coil former. Several thin magnetic sheets (9) are wound round parts (A, B) of the outer surface of the guide cylinder through which flows the magnetic flux. The thin sheets with controlled electric and good magnetic properties are inserted between the guide cylinder (5) and the coil former (2). They are so would round the outer surface of the guide cylinder as to cover the magnetic flux paths of the guide cylinder.</p> |
