1316950 Reciprocating generators UNIVERSITY COLLEGE OF NORTH WALES 26 June 1970 [30 June 1969] 33019/69 Heading H2A A generator utilizing oscillatory motion of, for example, the sea, vehicle suspensions, pedestrians or animals comprises a frame 1 consisting of rods 2 carrying at one end an end plate 3 and at the other end a stator 4 formed of permanently magnetized, annular laminations. An axial magnetic core 5 defines an annular gap 6 in which moves an armature 7 having distributed phase windings wound on a cylindrical carrier 9 carrying a lead mass 11 and suspended from the plate 3 by springs 10 which in addition to producing oscillatory motion of the armature on bodily acceleration of the generator, carry current generated in the armature windings to terminals 13. The rods 2 may be replaced by a sealed, cylindrical casing, Fig. 2 (not shown), either evacuated or filled with inert gas and the carrier (9) may support output rectifiers. Alternatively the armature may be mounted so as to slide on the rods, Fig. 3 (not shown), the resilient connection in this case comprising compression springs (17) surrounding the rods. |
