    摘要: There is described a revolving device for a conveyor chain or a conveyor belt, wherein at least one magnet exerts an attracting or a repelling force on the conveyor chain and/or the conveyor belt in order, in particular, to reduce wear and tear during high speeds and to cushion vibrations. The magnetic flux is thereby concentrated in such a way by a first flux guide piece that the magnetic flux acts vertically upon an effective surface of a component of the conveyor chain and/or the conveyor belt. In interaction with a second flux guide piece, the return of the magnetic reflux is achieved by of an additional component of the conveyor chain and/or conveyor belt. Thus the magnetic reflux does not occur by way of the first named component, and consequently an optimized exertion of force on the conveyor chain and/or conveyor belt results.

    摘要: In a magnetic bearing arrangement, support coils are connected in series and can be fed with a current. By coupling a point connecting the two support coils to a voltage source, the support coils can be used as actuating elements and, by feeding the support coils with voltage pulses, the inductance of the support coils can be inferred which is an indication of the position of the body to be mounted. This provides for a position control arrangement. Using one and the same support coils, both a stably controlled load-bearing capacity can thus be produced and at the same time a position sensor can be replaced.

    摘要: A synchronous linear motor with primary part having a winding and a secondary part including an elongated bearing plate to which the pre-magnetized permanent magnets of brittle and corrosion-prone material, are firmly adhesively secured while maintaining the pole pitch grid. In order to be able to securely bond the pre-magnetized permanent magnets to the secondary part economically and with high precision, it is proposed that spacers (2,3) corresponding to the pole pitch grid of the synchronous linear motor be arranged between pre-magnetized permanent magnets (4).

    摘要: The invention relates to a magnetic bearing control device and the use of a three-phase converter for controlling a magnetic bearing. According to the invention, a three-phase converter (70) is used for controlling a magnetic bearing (10, 66, 68), all three phase currents (40, 42, 44) of the converter (70) being used for controlling the magnetic bearing (10, 66, 68). A first solenoid of a couple of solenoids (10) of the magnetic bearing (10, 66, 68) is connected to a first (U) and a third (W) phase current output of the converter (70) while a second solenoid of the couple of solenoids (10) is connected to the first (U) and a second (V) phase current output of the converter such that the couple of solenoids (10) can be differently controlled by means of said one converter (70). The converter (70) can also be connected to magnetic bearings that already have a bias winding, which is advantageous for retrofitting such existing magnetic bearings, for example.

    摘要: A linear motor includes a primary part which is cooled using a coolant circuit to remove heat loss caused in the current-carrying conductor windings so as to prevent excess operational temperatures in the linear motor. In order to allow the linear motor to be used in immediate proximity of a production machine without affecting operation thereof by interference occurring in the work zone and without affecting the work zone through heat released by the linear motor, the primary part is completely encapsulated by an enveloping casing in conjunction with a cooling plate through which coolant flows. The cooling plate represents the element by which the primary part is secured to the machine part to be moved of the production machine.

    摘要: In a method for operating a three-phase inverter of a converter-fed magnetic bearing, two coils are connected to respective outputs of the three-phase inverter at one end and are connected to each other and to a third output of the three-phase inverter at the other end. A variable control current is injected into the third output. A constant bias current flows between the respective outputs and thus serially through the two coils. The control current is divided among the two respective outputs so as to flow parallel through the two coils. This arrangement significantly reduces the effective current load of the three-phase inverter and significantly increases the slew rate of the control current.
