Abstract

1341050 Transformers and inductors MAGNETECH INDUSTRIES Inc 1 June 1971 [2 June 1970] 18273/71 Heading HIT A variable inductor comprises a laminated core 10 having a removable end portion 12 secured by pegs 28, and two leg portions 26A, 26B, each of which non-rotatably supports a cylindrical member 24A, 24B. Embedded in the members 24A, 24B are primary coils (56A), (56B) (Fig. 4, not shown) and secondary coils (62A), (62B). Cylindrical drums 14A, 14B are rotatably mounted on the members 24A, 24B and respectively carry windings 16A, 16B, the turns of which may be transferred from one drum to the other by synchronous rotation of the two by a belt 32 which engages teeth 34 on end flanges 36 of the drums, and a driving gear (38) (Fig. not shown). One drum 14B has a fixed coil 40 embedded therein, this coil being connected in series with the coils 16B, 16A. The free ends of coils 16A, 40 are connected to brushes 20A, 20B respectively, which respectively slidably engage commutators 22A, 22B. The commutators comprise disc-shaped insulators (70) (Fig. 5, not shown) and a segmented ring (72) of conductors (75) connected by conductors 80 such that voltages induced in adjacent conductors are in series opposition and are thereby self-cancelling. For a given A.C. input on the primary 56A, 56B (Fig. 7, not shown) a fixed output is obtained from the secondary 62A, 62B and a variable output is obtained across the winding 40, 16A, 16B by virtue of windings 16A, 16B being connected in series opposition and their respective number of turns being variable.
