摘要： A variable-reluctance electric motor comprises a stator of ferromagnetic material, having poles provided with induction windings and distributed in four equal groups. The motor is provided with at least one ferromagnetic material rotor ring having equidistant teeth and bearing switching means actuated by the rotation for distributing direct current to the stator windings. The windings and switching means are so combined that, during each advance of the rotor by one tooth pitch, each pole is subjected to two opposite switching operations staggered by a time equal to that taken by the motor for a one-fourth of a tooth pitch rotation. The stator poles are equidistant, each bearing one winding, and are number (4kl), k being at least equal to 2 and l being any number. The rotor has (lm) teeth, m being an odd number greater than (4k). The switching means are so actuated as to switch over the d.c. supply from one stator pole to another one every time the rotor advances by (1/k) of a tooth pitch, and m is so chosen that at any instant energized poles alternate with non-energized ones, except in the stator parts which have just undergone or are about to undergo switching.

摘要： To obtain in a brushless d-c motor a speed control signal which is dependent both on rotational speed and on armature current in a predetermined mix, each of n armature winding has a diode connected thereto with one terminal, all terminals of the diodes being connected together to provide a first control voltage which coupled out from the windings during current flow therethrough and is representative of a composite of the emf induced by the field of the rotor in the n armature windings and of resistance voltage drop due to the current flow through the respective armature windings; resistors have one terminal, each, connected to the same n respective armature windings and the other terminals together to provide a common resistor junction at which a second control voltage is derived representative of 1/n of the resistance voltage drop due to current flow through said n armature windings. The two control voltages are normalized or weighted with respect to each other, compared, and the comparison is applied to a speed control circuit which will be responsive to armature current and to induced voltages. Positive or negative feedback can be introduced, in dependence on armature current, by affecting the normalization or weighting ratio.

摘要： A pair of serially connected transducer elements, typically magnetically responsive diodes, are connected across the source of voltage supply; the resistance of the diodes changes, depending on their being subjected to a magnetic field, for example by a permanent magnet rotor. The junction between the serially connected diodes is connected, in turn, to a logic circuit which has a supply terminal input to which a controlled potential can be applied. Depending upon the voltage level at the junction between the transducer elements (magnetic diodes) one or the other output of the logic circuit is connected to the supply terminal so that, upon connection of a controlled voltage (for example representative of a speed control signal) one or the other output terminal is accordingly energized to, in turn, accordingly energize a transistor connected in series with the logic circuit to control current flow through armature windings of the motor.

摘要： In a method and corresponding circuitry for controlling a rectifier circuit having a controlled rectifier, the controlled rectifier is fired at an electrical angle Alpha and is quenched at an electrical angle Beta . A circuit arrangement is provided for establishing a quenching period during which quenching of the controlled rectifier occurs. This quenching period begins at an electrical angle after the A.C. supply current has reached its maximum value and ends prior to the electrical angle at which the A.C. supply voltage subsequently crosses through zero. The controlled rectifier is quenched at an angle Beta lying within the quenching period and having a value which is adjustable in dependence on a momentary value of the A.C. supply current.

摘要： An apparatus for controlling a direct-current electric motor having a contact-less commutator, a rotor in the form of a permanent magnet and a stator with a three-phase winding is disclosed, said apparatus comprising a magnetic clutch of which the drive part is coupled with the output shaft of the motor and the driven part supports the rotor of a pickup responsive to the position of the rotor of the motor and the rotor of a braking electric machine, which is adapted to vary automatically the position of the axis of the magnetic flux of this rotor position pickup relative to the axis of the magnetic flux of the rotor of the motor and thus to adjust the speed of the motor. The apparatus ensures a high degree of stabilization of the motor speed within a wide range of controllable speeds and is employable, e.g. in various tape-driving mechanisms.
