摘要： 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.

摘要： 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.

摘要： An electric motor with quenching capacitors, particularly a miniature motor of this type, has a carrier ring supporting the capacitors and seated on the rotor shaft concentric therewith. The ring is secured to soldering flags which also connect the capacitors with the commutator segments of the rotor whereby all the capacitors can be assembled as a structural unit on the rotor without causing imbalances and can also be conveniently connected to the commutator segments of the rotor.

摘要： The ratio between the two states of an astable multivibrator is varied in dependence on the difference between a reference voltage and the output of an alternating current generator driven by the motor, a speed of which is to be regulated. One output of the multivibrator is connected to control the conductivity of a power transistor that controls the flow of current to the motor.

摘要： 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.

摘要： Electrical controls which include a resonance circuit connected electrically to an oscillator and having a plurality of circuit elements to one of which an output means is connected in parallel. A regulating means coacts with one of the circuit elements for influencing at least one of the parameters of the circuit. For example, the circuit may include an inductance coil and the regulating means may take the form of a permanent magnet which is moved in a predetermined manner with respect to the inductance coil so as to achieve in this way the controls of the invention. The output means is connected through a transistor, for example, to an element such as a stationary coil section of a commutator-less direct current motor, or the structure may act as a switch for controlling a circuit, so that in this way the structure will form an incorporeal switch.
