Definitions
- the invention relates to a device with the features of claim 1.
- Such devices are e.g. needed to set a waveguide switch or a coaxial switch.
- the aim of the invention is to effect the setting in the three positions - seen in one direction of rotation - via a single line pair and to bring the rotor of the switch exactly into the three desired positions without mechanical locking means and to hold it there, particularly in the middle position is problematic, but is achieved by the solution according to the invention.
- FIG. 1 of the drawing shows a basic illustration of an exemplary embodiment of a waveguide switch in its three switching positions item 1, item 2 and item 3.
- the inputs A are connected with B and C with D
- the switching position item 1 2 the inputs B with C and A with D and in switching position item 3, the inputs A with C and B with D.
- the control of the waveguide switch 7 is intended to be rotated in one direction via the line pair I and in the other direction via the line pair II, separate windings being provided for the two directions of rotation.
- the drive systems for the two directions each have two drive windings I 1 and I 2 or II 1 and II 2 .
- the cogging torque curve 4 is from left to right first seen from a moment (4a) driving the rotor against the stop 2 (item 1), then from a course 4b which drives the rotor 1 to the right into position 3, then from a course 4c which follows the rotor 1 drives to the left into position 3 and then from a moment (4d) driving rotor 1 to the right to stop 3 (item 2).
- the directions of the moments acting on the rotor magnet or magnets are shown by solid arrows.
- an oppositely effective drive torque 6 corresponding to the drive torque 5 is required, which is shown in dash-dot lines.
- the solution according to FIG. 4 has the advantage that the abutment of the rotor 1 against the stops 2 or 3 enables heat to be dissipated. If this is not necessary, the end positions (items 1 and 2) can also be determined by magnetic centering, but it will then preferably be followed by stops for safety. A corresponding torque curve is shown in FIG. 5. In the central area (4'b) of the impressed cogging torque curve 4 ', the curve corresponds to that of FIG. 4. However, the end positions (items 1 and 2) are now through the zero crossings (in items 1 and 2) of the cogging torque curve 4' in the Areas 4'a and 4'c determined.
- the drive torque drops favorably towards the stop 3. It is understandable that the drive torque must be large enough that it can overcome the respective cogging torque.
- the word "cogging torque curve" used above is intended to act on one or more rotor magnets 12 (see FIG. 6a), which is embossed on the stator 8 (see FIG. 6a) by designing and arranging permanent magnets 9, 10, 11 (see FIG. 6a) Designate torque curve according to Figures 4 and 5.
- the magnetic centering corresponding to item 3 in FIG. 4 and corresponding to FIGS. 1, 2 and 3 of FIG. 5 is achieved by a specially designed permanent magnet element 9, 12 (see FIG. 6a).
- 4 is achieved by a drive system corresponding to FIG. 6b, different windings I 1 , I 2 / II 1 , II 2 being provided for each direction of rotation, to which different permanent magnet arrangements 13, 14 are assigned on the rotor side (see FIG. 6b) are.
- Fig. 6 a device is shown in principle in a partial development
- Fig. 6a shows the locking arrangement
- Fig. 6b the drive.
- the latching arrangement (detend element) 9, 10, 11, 12 is arranged on the rotor 1 and on the stator 8.
- the permanent magnets 10, 11 of the permanent magnet pairs are offset from one another by approximately 13 °.
- the rotary movement of the rotor 1 is limited to an angle of 90 ° by stops 2, 3 made of strongly damping material.
- the rotor 1 On the rotor 1 is the other part 12 of the locking element 9, 12, which is also assigned to item 3, as well as the rotor attachments 2 ', 3'.
- Fig. 6b represents the, according to the latching arrangement.
- 6a shows an axially offset drive of the device.
- two permanent magnet pairs 13, 14 of different sizes are arranged offset by 180 ° and a magnetic yoke 15.
- the stator 8 contains four windings I 1 , I 2 , II 1 , II 2 , shown here symbolically as a simple conductor with the current direction shown, of which the windings I 1 , I 2 for rotation in one direction of rotation and the windings II 1 , II 2 can be used for rotation in the other direction.
