Title: Rotary electromagnetic positioning device
IPC: G08C19/40
Filed: 1952-08-25
Abstract: 707,724. Selsyn machines. ACKERMAN, H. B. Aug. 25, 1952, No. 21271/52. Class 35 In a selsyn machine in which a magnetized rotor moves to a position depending on the selective energization of a series of stator coils, all the stator coils are energized simultaneously for each rotor position and coil-sides in certain slots neutralize each other. To ensure reliable rotations through 180 degrees, asymmetry is introduced into the field of either the stator or rotor. The stator coils are all connected in series and may be fed at any particular coil so as to energize the coils in two groups in opposite directions to produce a field in a certain position. In the form shown, having a permanent or electromagnet rotor 29, the stator has twelve slots 1-12 carrying twelve coils, e.g. 1c, 2c &c. which are shortpitched to 150 degrees. By means of a multiple switch 26 having a series of double-pole switches 1s, 2s ... 12s the stator may be energized at any coil so as to select one of the twelve possible rotor positions. With switch 1s closed as shown, current flows by wire 1a to coil 1c in slot 1 and also by wire 1b to coil 12c in slot 7, so that the stator is fed with current at two diametrically opposite points and flows by two paths of unequal length round the two halves of the stator and leaves at conductors 1x. The resulting rotor position is as shown. The same happens for different switch and rotor positions, the switches being interlocked so that only one may be closed at a time. It can be seen that the currents in slots 1 and 2 on either side of tooth P. are in opposite directions and so create no field in that tooth with the result that the flux axis does not pass through the centre of the machine, this asymmetry giving the required reliability of movement. In a modification, not shown, the stator flux is made symmetrical by using the adjacent conductor, i.e. 12x as the outlet for the coil 1 instead of the one leading to the next slot, i.e. 1x as above; and so on for each switch position. In this arrangement, opposite slots, i.e. 1 and 7, have opposing coil sides instead of adjaccent ones, so that the stator flux is symmetrical. In this case the rotor is rendered unsymmetrical by chamfering the poles on one side and magnetizing it on an oblique axis.
