Patent GB-1218703-A (GB)
Title: Stepping motor for a large number of steps per revolution
IPC: H02K37/14
Filed: 1969-05-16
Abstract: 1,218,703. Electric motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 May, 1969 [20 May, 1968], No. 25126/69. Heading H2A. 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, 9<SP>1</SP> having interdigitated teeth 13, 13<SP>1</SP>, 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. 5<SP>1</SP>, 5<SP>11</SP> 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 5<SP>1</SP> 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.

Title: Improvements in and relating to alternating current electric motor equipments
Inventor: PEARCE KENNETH MAXWELL
IPC: B66B1/12
Filed: 1952-10-08
Abstract: 733,493. Control of A.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 30, 1953 [Oct. 8, 1952], No. 25253/52. Class 38 (3). An induction motor 1 is braked by connecting its stator winding to a direct-current source whilst the circuit of the slip-ring rotor winding 2 is closed through a variable resistance 8. A servo-motor 10 for moving the electrodes of the braking resistance is supplied from an amplifier 11. A transformer has its primary winding 12 energized in accordance with the rotor voltage, its secondary winding being connected through inductance 15 and rectifier 14 to a load resistor 16. A current transformer 17 is connected in one of the rotor leads and has its secondary winding connected by means of rectifier 18 with a load resistor 19. When the voltage across the resistor 16 exceeds that derived from the resistor 19, the input to the amplifier 11 is such that the braking resistance is reduced, whereas, when the rotor current increases with relation to the rotor voltage, the braking resistance is increased. The inductance 15 causes the current supplied to the resistor 16 also to vary inversely as the rotor frequency so that the braking resistance is automatically controlled to a value which is substantially proportional to the motor speed. The braking resistance may, however, be controlled as a non-linear function of the speed by means of appropriate impedance networks in the circuits associated with the voltage and current transformers. In another arrangement, the inductance 15 is omitted and a capacitor connected in series with the secondary winding of the current transformer. The voltage across the resistor 19 is thus proportional both to the rotor current and frequency, Fig. 2 (not shown). In a further modification, an inductance connected across the secondary winding of the current transformer provides a voltage proportional to the rotor current and speed, Fig. 3 (not shown). The resistor 16 may be connected as a potentiometer with a movable contact which is adjusted by a centrifugal governor driven by the motor, Fig. 4 (not shown). The amplifier 11 may be of the phase-sensitive type with its input circuit including means responsive to rotor voltage in series opposition with the secondary winding of a quadrature transformer having a primary winding energized in accordance with the braking current, the output of the quadrature transformer being proportional to the rotor frequency, Fig. 5 (not shown). The braking resistance may be of the contactor-controlled metallic type, the contactors being regulated by a sequence switch.
