  • METHOD FOR STARTING AN ELECTRIC MOTOR IN A HYDRAULICALLY OPERATED WORKING MACHINE
    Publication number: 20130171007
    Abstract: The invention relates to a method for starting at least one asynchronous electric motor of a large hydraulic excavator having a service weight >100 t and having an electrohydraulic drive, in that the particular electric motor is transferred from an idle position to an operating position by using a three-stage motor starting process, wherein the volumetric flow rate of at least one hydraulic pump operatively connected to the electric motor is set to the delivery rate V=0 during all starting stages of the electric motor and the delivery rate V of the hydraulic pump is controlled to a value >0 only after the last starting stage of the electric motor by activating an actuator.
