    • An arrangement for maintaining constant the speed of DC motors. The motor is mechanically coupled to a generator the electrical output of which is added to a reference voltage. A power transistor is connected in series with the motor through its emitter-collector path. The power transistor may be driven by a preamplifying transistor stage. A regulating transistor applies the signal for the power transistor to the preamplifying stage. The power transistor varies the motor current as a result of its conducting state. An auxiliary voltage source connected to the motor provides voltage potential dependent upon the motor load. This potential is applied through the feed-back circuit including the regulating transistor, to the power transistor, in order to vary the conducting state of the latter in accordance with the motor load.
    • 用于保持直流电动机速度恒定的装置。 电机机械耦合到发电机,其电输出被添加到参考电压。 功率晶体管通过其发射极 - 集电极路径与电动机串联连接。 功率晶体管可以由预放大晶体管级驱动。 调节晶体管将功率晶体管的信号施加到前置放大级。 功率晶体管由于其导通状态而改变电动机电流。 连接到电机的辅助电压源根据电机负载提供电压电位。 该电位通过包括调节晶体管的反馈电路施加到功率晶体管,以便根据电动机负载改变后者的导通状态。

    • A collectorless D.C. motor includes a rotor, a stator, and a plurality of stator windings arranged on the stator in angularly spaced relationship. Each winding when energized produces a stationary magnetic field having a respective orientation. A control circuit including an oscillator energizes successive ones of the windings for respective time intervals determined by the oscillatory frequency of the oscillator. The resulting magnetic field revolves with an angular velocity determined by the oscillator.

    • In a transistor control circuit which comprises a number of control stages corresponding to the number of windings of a multipole stator, the control stages are joined together to form a closed chain, each control stage being connected to the following control stage by means of a first RC network, and being connected to the preceding control stage by means of a second RC network. The said first RC networks are all of uniform rating and the said second RC networks are also all of uniform rating but of a rating which differs from that of the first RC networks, and the first and second RC networks connected to the input of each control stage have a common resistance or capacity component.
