    摘要: A method and apparatus are disclosed for inserting a pouring pipe into a mold of a continuous casting machine. The pouring pipe is mounted in a truck, and the truck and pouring pipe combination are then mounted on a conveyor mechanism such that the pouring pipe is set in a substantially horizontal starting position. From this substantially horizontal starting position, the pouring pipe is guided along a pair of guide rails of the conveyor mechanism such that is pivots into a substantially vertical position and is moved into a waiting position wherein its lower end is inserted into the mold. In this waiting position, the pouring pipe is offset laterally from but aligned with a casting opening in the bottom wall of the metallurgical vessel. From this waiting position, the pouring pipe can be forced by a pusher mechanism into a pouring position beneath the casting opening of the metallurgical vessel, such that molten metal can be poured from the metallurgical vessel into the mold via a pouring pipe. This procedure can be repeated by moving a new pouring pipe into the waiting position, after a pouring pipe in the waiting position has been moved from the waiting position into the pouring position, thereby displacing the eroded pouring pipe from the pouring position into a discharge position from which it can be removed from the continuous casting machine.

    摘要: The present invention relates to a method for operating a brushless electric motor whose windings are driven by an inverter with the aid of six switches, having an identification unit being provided in order to identify defective switches, a unit for voltage measurement at the outputs of the inverter, and a microcontroller for controlling the switches. Particularly in safety-relevant applications, it is important to quickly determine what characteristic the defective switch has, for example in order to continue to operate the electric motor in an emergency mode, or to switch it off immediately. The defect (F1, F2, F3) is traced and the nature of the defect (F1, F2, F3) in a switch determined by using a different voltage (PWM1, PWM2) to drive those windings (V, W) which are not associated with the defective switch, while a voltage measurement is carried out on the winding (U) associated with the defective switch.

    摘要: An internal combustion engine includes an electromagnetic actuator for operating a gas exchange valve, this actuator being situated on a cylinder head. The actuator includes a switchable electromagnet which is situated between two armatures. The armatures are axially set apart on a common armature shaft. A cavity is configured in the cylinder head, in which the actuator armature on the cylinder head side is at least partially accommodated, and the electromagnet at least partially delimits the cavity on the actuator side. This results in a compact internal combustion engine.
