Patent ES-362232-A1 (ES)
Title: Control systems for electric motors
IPC: H02P7/29
Filed: 1969-01-08
Abstract: A D.C. motor is energized by pulses which are initiated when the armature current is below an adjustable predetermined value, as detected by an arrangement coupled to a voltage divider, part of which comprises an element whose impedance varies according to magnetic flux through it, the flux being produced by a conductor carrying the armature current. The element consists of a Hall device MR1 and a winding 11 for the current assuming this is already flowing, when it is high enough to cause a transistor TR1 to conduct capacitor C4 is charged until its voltage is sufficient to cause conduction of further transistors TR4, TR5 to thereby trigger a thyristor TH2 and so produce a triggering pulse for a " turn off " thyristor (22, Fig. 1, not shown) in the motor circuit. This terminates a pulse and the armature current decays through a flywheel diode until the impedance of the Hall device drops sufficiently for TR1 to turn off this allows a transistor TR2 to turn on to trigger a thyristor TH1 which in turn triggers an " on " thyristor (17) in the motor circuit and so start a new pulse and hence repeat the cycle. The time constant of C4 determines the minimum pulse length. The effective value of the armature current, and hence the motor speed, is varied either by a bias signal in a winding 31, by movement of a permanent magnet 33, by varying the otherwise constant voltage (which may be direct or alternating) applied to the Hall device by making resistor R2 adjustable, or by varying the threshold level of TR1. The motor is a series machine having separate forward and reverse field windings and in Fig. 3 (not shown) separate control circuits are provided for each direction, with an interlocking cross-connection.

Title: Stepping motor for a large number of steps per revolution
IPC: H02K37/14
Filed: 1969-05-17
Abstract: In a stepping motor comprising at least three coaxial stators, e.g. 1, each including at least one annular coil 5 arranged between two soft ferromagnetic plates 9, 91 having interdigitated teeth 13, 131, and at least one P.M. rotor 21 having peripheral poles of alternate polarity, and in which the number of poles of each rotor is the same as the number of poles on each stator, the angle between the pole of each stator and its associated rotor pole is different from the angle between the poles of every other stator and its associated rotor poles by an amount m/n times the pole pitch, where n is the number of stators and m is an integer between 1 and (n-1). The motor shown has four stators 1, 2, 3, 4 and four rotors 21, 22, 23, 24, the poles of the rotors being axially aligned. Alternatively a single continuous rotor may be used. Each of the stators has 24 interdigitated teeth so that the teeth of stators 2, 3, 4, for example, are out of alignment with those of stator 1 by 3 degrees 45 minutes, 7 degrees 30 minutes and 11 degrees 15 minutes respectively. Alternatively the stator teeth may be aligned and the rotor poles staggered, or both the stator poles and the rotor poles may be out of alignment so long as the relative spacing requirement is met. Each coil 5, 6, 7, 8 is made in two halves, e.g. 51, 511 adapted for energization in opposite directions. In a first operating mode all of the coils 5, 6, 7 and 8 are energized and the rotor is stepped in a given direction by reversing the energization (e.g. by switching over from 51 to 511) of that winding whose poles are most out of alignment with the associated rotor poles when viewed in the opposite direction. A switching sequence is described with reference to Figs. 3, 4 (not shown) giving 96 steps per revolution. In a modified operated mode giving 192 steps per revolution, the motor alternately operates with four and three windings energized. To produce the next step when four windings are energized that winding whose poles are most out of alignment with the rotor poles (when viewed in the opposite direction) is de-energized and to produce the next following step that same winding is energized in the opposite direction. A switching sequence is described with reference to Figs. 6, 7 (not shown). The eight half windings are energized through a switch having eight equi-angularly spaced contacts energized by an arcuate wiper connected to one polarity of a supply and driven by a second stepping motor having eight steps per rev. or 16 steps per rev. respectively for the 96 steps per rev. and 192 steps per rev. operating modes of the motor.
