Description
This old beaut was an AC Slip-ring induction motor, coupled electrically (and mechanically) to a DC Generator. The blurb informed me that it was to provide DC to some of the customers in Johannesburg who were still using DC to run lifts and motors; a throwback from when DC was in use in Johannesburg so many years ago (1905). This supply from here was discontinued in the 1990’s.
