Abstract

697,371. Dynamo-electric machines. AKTIEBOLAGET VIBRO-BETONG. Nov. 22, 1951 [Nov. 23, 1950; May 17, 1951], No. 27376/51. Class 35. In a gyratory vibrator the rotor body rotates about its axis under a magnetic field produced by the stator and rolls on circular tracks concentric with the stator so as to gyrate, without tilting, about the stator axis, In one form, Fig. 2, the laminated squirrel cage rotor 2 is revolved about its own axis by a rotary field produced by the stator 1 and gyrates about shaft ends 4 extending partly or completely through a central bore 3. The rotor periphery carries annular discs 6 running in grooves 7 to prevent tilting. In a modification, the rotor body has no central bore and carries projecting toothed wheels which roll round in recesses in the end-shields. In a further modification, Fig. 5, two axially disposed stators 10, 11 produce an axial rotating flux which passes through the rotor, the spirally laminated cores of the stator and rotor carrying respectively windings 12, 13 and a squirrel cage 16. The rotor rolls on conical surfaces 20, 21 and a casing 23, 24 enables the vibrator to be used for immersion in liquids. In modifications, only one stator core may be used and the rotor may gyrate about a central bolt.
