BUCYRUS 2000:InnovativeSpeedControlby Bucyrus America,Inc.

Intheearly1970's,S&SCorporationleadthewayinmininginnovationwiththeintroductionof SolidStatespeedcontrolsforbattery-poweredundergroundminingequipment.SolidState controlsincreasedtherangeandreliabilityofthebatterypoweredvehiclesalongwithproviding smooth,steplessacceleration.Evenwithsolidstatespeedcontrol,directionchangewas achievedwiththeuseofelectromechanicalcontactors.Thesecontactorsprovidedanendless sourceofmaintenanceproblemsandconsumedexcessiveamountsofvaluable controller-box space.Also,mostsolidstatecontrollersofthepastutilizeanelectromechanical"bypass" contactortoconnectthemotordirectlytothebatterieswhichcausedmorecontactorproblems.

Inthe1980’s Bucyrus America, Inc., inconjunction withSevcon,developedacontactorlessmotor controller(X90)tobeusedexclusivelyon Bucyrus equipment.TheX90systemusedadual-field motorincombinationwithSCR's(SiliconeControlledRectifier)toachievesolidstatedirection change.

Now Bucyrus America, Inc., inconjunctionwithSevcon,hasdevelopedtheBucyrus2000motor controller.TheBucyrus 2000systemusesIGBT’s(InsulatedGateBipolarTransistors)toachieve motorcontrolanddirectionchange.UnlikeanSCR,anIGBTisturnedONand OFFviaagating electronicsignal.Thiseliminatedcommutatingcapacitorbanksandcoils.Themicroprocessor basedBucyrus 2000LogicCardprovidescompletemotorcontrol,anddrivesbothaDiagnostic DashboardDisplayalongwithahandheldCalibrator/DiagnosticUnit.
