摘要:
A method is proposed for distributing current to the existing current directing valves or switches in the inverting converter of adjustment drives with synchronous servo-motors when the end position of the adjustment drive is reached at a time when the torque or force load is high in which the current space indicator of the current is moved electrically through ±90° about the desired end position with sufficient frequency.

A method for an electrical supply of electric setting mechanisms of motor vehicles, particularly of electromagnetic energy converters, with prevailing generator operating modes. One electromagnetic energy converter is coordinated with one accumulator element electrically connected with the power supply or with the power supply battery, the supply voltage of the one electric setting mechanism or of the one electromagnetic energy converter (2) is increased in comparison with the power supply voltage.

A transmission device (3) for a vehicle with an electric machine (26) that is arranged in a housing (11) is described. The electric machine (26) can be placed in active connection with a rotating component (13, 28) that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine (26) can be transmitted to the component (13, 28). At least one electric component (45; 45Y) that comprises power electronics for the electric machine (26) is arranged in a cross-sectional area inside the housing (11) that is perpendicular to the longitudinal axis of the electric machine (26) and is located directly adjacent to the electric machine (26).
摘要:
An electrical charging system having a rectifier which is supplied with energy via an input. An inverter whose alternating voltage side is connected, via phase conductors, to windings of a rotating field machine and whose direct voltage side can be connected to an energy accumulator to be charged. A first current path section passes current, supplied by the rectifier, into the charging system via the plus terminal or pole of the rectifier and the rotating field machine to the inverter. The first current path section passes the current via phase windings of the rotating field machine, such that the first current path section comprises a first switch, which can selectively interrupt the first current path section. The charging system can operate, by the first switch and at least one phase winding in the first current path section, as a step-up and step-down converter in the direction toward an energy accumulator.

The objective of providing a circuit arrangement for the control of at least one electric machine (1), which is suitable for also enabling operating conditions of the electric machine (1) that demand high power-peaks of short duration, is essentially achieved in that the electric machine (1) can be connected via a DC/AC converter (2) and at least one switching device (3) to at least two different electrical energy storage devices (I, II), one storage device (I) being designed as a storage device for comparatively long-lasting power demands and the other storage device (II) as a storage device for short and high power-peaks.
摘要:
An electrical charging system for an energy accumulator of a motor vehicle. The electrical charging system comprises a supply input in a conductor system having at least one phase conductor and a neutral line for energy supply from a grid. The charging system also comprises a rotating field machine which, via its phase windings, is operably connected to a rectifier. The rectifier is provided on the other side for connection to the energy accumulator to be charged, the phase windings of the rotating field machine can be either selectively isolated and interconnected such that the charging system is designed for step-up connecter charging operation and step-down charging operation by way of at least one isolated phase winding and, in particular, all the isolated phase windings.
