  • Patent number: 5087864
    Abstract: An apparatus for selectively controlling a plurality of electric motors for driving individual work objects, the apparatus including an electrical switch which is adapted to produce predetermined speed signals for the electric motor selected, a programmable controller disposed in signal receiving relation relative to the electrical switch and which is adapted to generate a predetermined signalling sequence in response to the signal received from the electrical switch, a variable speed motor drive electrically coupled with the programmable controller, and with the electric motor selected, the variable speed motor drive selectively driving the selected electric motor at a predetermined speed in response to the signalling sequence received from the programmable controller, and a sensor adapted to indicate the work performed by the electric motor whereby the electric switch may be selectively adjusted to control the operation of the electric motor selected.
