    摘要: An electric AC machine with a primary section and a secondary section is disclosed. The primary section has a region facing the secondary section and a region facing away from the secondary section. The region facing the secondary section has windings adapted to receive an AC current. The winding of the primary section has at least one phase conductor which at least partially extends in or on the region of the primary section facing away from the secondary section, thereby producing a magnetic field that extends outside the secondary section. This arrangement can reduce overvoltages and eliminate voltage breakdowns at the star point of winding strands of a synchronous motor.

    摘要: A device and a method are disclosed for attenuating a chatter oscillation in a processing machine, for example a cutting machine, such as a lathe. The machine includes at least one feed system with a primary section and a secondary section driven by a linear motor which can be powered via a converter. The device has a magnetic field control to control an in-phase component (d-component) of the magnetic field which produces the attractive force between of the primary section and the secondary section. An actual signal that is proportional to the chatter oscillation is generated and compared with a predetermined setpoint for a chatter oscillation. The comparison produces a control variable which is applied as a current setpoint to a field control that controls the current of the linear motor. This sufficiently attenuates chatter oscillations so that a reduction of the cutting depth is no longer required.

In order to prevent phase distortion and the like in controlled systems, a sensor (250) for detecting the state of movement of a motor (200) is provided directly on or in the force transmission interface (270) of the motor. The sensor can, for example, determine the position, speed or acceleration directly. The invention is particularly suitable for controlling linear motors in high-precision applications, such as machine tools, milling machines or pick-and-place robots.

    摘要: The invention relates to a machine for machining workpieces, for example a milling machine or a lathe, including imbalance sensors (60) for determining the imbalance of a rotary element, i.e. the cutter head (40) or of the workpiece (10) to be worked on. The advancement of the workpiece (10) relative to the tool (40) is so corrected in dependence on signals of the imbalance sensors (60) that a possible imbalance deflection of the tool (40) can be compensated. Correspondingly, the tool feed can be so controlled in a lathe in dependence on the rotation angle position and the determined imbalance that balancing can be carried out during or directly after treatment of an imbalance.

    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.
