Abstract

The mercury-wetted commutator employs a stacked assembly. The latter is formed by alternately stacking stationary units 10 and rotary conductors 11, inserting rotary shaft 12, and locking the assembly together by end plates 13 and 14 and bolts 15. Units 10 include circular grooves 16 having conductors 17 and 18 laid in the bottom of such grooves. A predetermined amount of mercury 19 is then injected into each grooves 16. Conductors 11 are loosely keyed on shaft 12 and rotate with it. The plates are free to move axially along the shaft 12 and thus float on the surface of mercury 19. The conducting plates are connected, before assembly, to wires 20 and 21 which rotate with shaft 12.

Mercury Wetted Commutation

The mercury-wetted commutator employs a stacked assembly. The latter is formed by alternately stacking stationary units 10 and rotary conductors 11, inserting rotary shaft 12, and locking the assembly together by end plates 13 and 14 and bolts 15. Units 10 include circular grooves 16 having conductors 17 and 18 laid in the bottom of such grooves. A predetermined amount of mercury 19 is then injected into each grooves 16. Conductors 11 are loosely keyed on shaft 12 and rotate with it. The plates are free to move axially along the shaft 12 and thus float on the surface of mercury 19. The conducting plates are connected, before assembly, to wires 20 and 21 which rotate with shaft 12. Current is transmitted by wires 17 and 18 to mercury 19 in the stationary housings, via mercury 19 to conductors 11, and from the latter to wires 20 and 21 in shaft 12.
