摘要： A control circuit is described in which a single input terminal receives digital control signals and analog control signals. In accordance with the principles of the invention, the control circuit includes an automatic power down circuit to place the control circuit into a low power draw or “sleep” mode whenever predetermined conditions are present. The automatic power down circuit monitors the single input terminal and when no demand for motor operation occurs for a predetermined period of time, the automatic power down circuit operates to place the control circuit into the low power draw mode.

摘要： An electronically commutatable motor with a preferably three-phase excitation winding in the stator, which, in order to generate a torque for a permanent magnet rotor, can be connected to a direct current source via a motor control unit and a commutation device equipped with semiconductor switches. The motor is intended for use as a drive motor of a safety-critical auxiliary drive unit in a motor vehicle, in particular as the drive motor of an electrical power-assisted steering unit, wherein additional or existing switching means suppress or at least partially compensate for a braking moment that is generated by the motor in the event of a winding short and/or a malfunction in the semiconductor switches of the commutation device.

摘要： A commutator arrangement for a small electric motor with a capacitor ring disk having several capacitor elements, wherein the capacitor ring disk is made of a dielectric first ring disk (RS) on whose upper side several sector-shaped electrode layers (6) are placed. Each of the electrode layers (6) are electrically conductively connected with a commutator segment (13). Counter electrodes of the capacitor elements are provided on an under side opposite the upper side. To improve the interference suppression features a single counter electrode layer (4), which underlies almost the entire surface of the electrode layer (6), is provided on the under side so that the counter electrodes of all capacitor elements have the same potential.

摘要： When power is sequentially supplied to the phase coils of a brushless DC motor, the rotor of the brushless DC motor is rotated. At this time, a voltage is induced in one of the phase coils to which power is not supplied. The rotational position of the rotor is detected from the induced voltage. The switching timing of power supply to the phase coils is determined in accordance with the detected rotational position. When a service operation mode switch is operated, a service operation is executed, and power supply to the respective phase coils is forcibly switched at a predetermined frequency. A failure can be diagnosed during this service operation.

摘要： An integrated CT scanner gantry assembly is provided wherein an open bore rotor is supported by a bearing assembly on an open bore stator. An x-ray assembly is mounted on the rotor and supplied with high voltage power during continuous rotation about the stator through use of a slip ring assembly which is mounted between the rotor and stator. The inside surface of the stator which faces a patient generally lies along the surface of a truncated cone to permit substantial tilting of the stator. Moreover, the stator and rotor have a cross section formed as a series of separated yet aligned steps to form two isolated cavities therebetween, one of the cavities housing the cathode of the slip ring and the other of the cavities housing the anode of the slip ring. The cavities can be filled with a gas or liquid high voltage insulating fluid and can be readily sealed to prevent leakage of said fluid. An x-ray assembly bracket is removably attachable to the rotor to support an x-ray source and x-ray optics in order to permit the x-ray source and x-ray optics to be assembled and aligned on the bracket at a location remote from the rotor and stator. The overlapping positions of the separated yet aligned steps relative to the x-ray source and optics assembly bracket reduces the cross-sectional area and overall gantry volume thereby providing comfortable patient access for whole body CT scanning.
摘要翻译：提供了一种集成的CT扫描器台架组件，其中开孔转子由开孔定子上的轴承组件支撑。 X射线组件安装在转子上并通过使用安装在转子和定子之间的滑环组件围绕定子连续旋转而提供高压电力。定子面向患者的内表面通常沿着截锥体的表面放置，以允许定子显着倾斜。此外，定子和转子具有形成为一系列分离但对准的步骤的横截面，以在它们之间形成两个隔离的空腔，其中一个空腔容纳滑环的阴极，另一个空腔容纳滑环的阳极。空腔可以填充有气体或液体高压绝缘流体，并且可以容易地密封以防止所述流体的泄漏。 X射线组件支架可拆卸地附接到转子以支撑X射线源和X射线光学元件，以便允许X射线源和X射线光学元件在远程位置组装和对准支架上从转子和定子。相对于x射线源和光学组件支架的分离的对准步骤的重叠位置减小了横截面面积和总体门架体积，从而为全身CT扫描提供了舒适的患者通路。
