So, "I put my thinking-head on.", as Worzel Gummidge used to say, and surmise that the motor would be series wound dc: speed is effectively controlled by the load. For a polisher, you'd get very high speed when lightly running a mop over the work, and vice-versa. Only vaguely connected with the above thread, and spitzapper never did get an answer to a rather vague question.
