Title: Drive device for step motor
Inventor: FUJISHIMA TOSHIHIRO
IPC: H02P8/22
Filed: 1983-02-17
Abstract: PURPOSE:To position a step motor at a high speed and to improve the resolution for positioning at a high speed by altering the exciting system of the step motor during high speed operation and immediately before the stop. CONSTITUTION:When a switch 21 is set to active, a pulse outputted from a pulse generator 18 is distributed by a 2-phase distributor 19, and transmitted to OR gates 14-17. The output of the 2-phase distributor is transmitted to step motor windings 6-9 as it is. When a switch 22 is similarly set to active, the output of 1-2 phase distributor is transmitted to the windings 6-9 as it is. Accordingly, the torque dring high speed operation is obtained by setting the switch 21 to active during high speed operation of the step motor, and the resolution capacity for positioning at the stop time can be raised by setting the switch 22 to active immediately before the stop.

Abstract: PURPOSE:To enable the working at a low frequency region, by loading at least three ferromagnetic materials having the same saturation magnetizing value, section form and thickness to the upper and lower sides of a junction part connected to at least three external transmission lines and then applying an external bias magnetic field. CONSTITUTION:Two sets of three disk ferrites 12, 12' and 12'' are set to the upper and lower sides of a common part at a Y junction of a strip line having a circular center conductor 11 so as to hold the conductor 11 between the pairs of these disk ferrites. In this case, the ferrites 12, 12' and 12'' are put close enough to each other so that they are connected to each other in terms of an electromagnetic circuit. Furthermore these ferrites are set so that the outer diameters of the ferrites are coincident with the diameter of the conductor 11 of Y junction and at the same time at the area close to the junction of coupling lines. Then the external circuit signal wave excites directly the ferrites 12, 12' and 12'' through coupling lines 10, 10' and 10''. The upper and lower ferrites are held from upper and lower sides by means of an earth conductor plate (not shown in the figure). In addition, an external DC bias magnetic field HDC is applied in parallel to a common shaft. As a result, a magnetic field can be swept over a wide frequency range higher than an octave band.
