摘要： An electromagnetic motor of the finite rotational type has an improved rotor-returning mechanism for exerting a magnetic force to return its rotor to the initial angular position in a non-excited condition. The rotor-returning mechanism is comprised of a permanent magnet fixedly mounted on a stator and a permanent magnet mounted around the rotor. The permanent magnets are arranged such that, a magnetic attractive force generated between the permanent magnets functions to return the rotor to the initial angular position. The rotor-returning mechanism can be constitued by first and second ring-shaped permanent magnets mounted on the rotor. The N and S poles of the first magnet are offset in a the circumferential direction from those of the second magnet so as to generate a magnetic torque for returning the rotor to the initial angular position.

摘要： A DC motor of a galvanometer-type scanner has four poles, and compared to a conventional DC motor with a bipolar construction, the armature inductance L can be reduced to half or less for a case where the external diameter of the rotor and the induced voltage constant KE are the same. Since KE/L, which is the index for the rise of torque of the motor, is increased by a factor of two or more, the responsiveness of the motor can be improved without increasing the exciting current of the winding. Accordingly, it is possible to provide a galvanometer-type scanner that can set minute angles of around one degree within several hundred microseconds.

摘要： An optical position sensor comprises a linearity correction circuit 20 having ROM 22 in which a corresponding table between compensation values and respective rotational angular position of a rotational disk 51. The compensation values are obtained such that an actual relationship is measured between the rotational angular positions of the rotational disk 51 and the output B of a semiconductor position sensing device 54, deviation of the output B of the device 54 from a predetermined linearity relationship (A) is calculated, and compensation values are determined for eliminating the deviation of the output B of the device 54 at respective rotational angular positions of the rotational disk 51. The linearity correction circuit 20 retrieves a compensation value E from ROM 22 based on the output B of the device 54, and compensates the output A so as to produce the sensing output E which has a linearity relationship to the rotational angle of the rotational disk 51.

摘要： First to fourth magnetic detection units (22-25) are arranged in opposition to a multipole magnetized surface (21a) of a multipole magnet (21) of a magnetic encoder (17). The first and second magnetic detection units (22, 23) are placed on positions separated from each other by 180 degrees on the periphery of the center of the multipole magnet and output an A-phase signal and a B-phase signal. The third and fourth magnetic detection units (24, 25) are placed on positions separated from each other by nearly 180 degrees on the periphery of the center of the multipole magnet and output an A-phase reverse signal and a B-phase reverse signal. Detection signals of the same phase are synthesized and averaged, and consequently a detection error generated by an outer magnetic flux extending in the diameter direction of the multipole magnet can be removed. The signal obtained by synthesizing the detection signals of the same phase and averaging the same and the reverse signal of a signal obtained by synthesizing reverse signals of the reverse phase and averaging the same are synthesized and averaged, and consequently the detection error generated by the outer magnetic flux radially extending in one direction along the radius direction of the multipole magnet can be removed.

摘要： In an actuator (1) in which an angle detector (13) of a magnetic encoder for detecting the rotational position of a motor (3) is incorporated inside a wave reduction gear (5), detection signals from Hall elements (11a, 11b) of the angle detector (13) are transmitted via sensor lead wires (17) that have been brought out through wiring holes (36a, 33a, 35a, 37a) formed inside the motor (3) to a sensor signal converter board (14) disposed on the rear end side of the motor. Since the wiring is not required to be brought out to the exterior, indirectly routed along the exterior of the motor (3), and brought out to the rear side thereof, the wiring is not mechanically damaged and can be brought out with the shortest possible wiring distance, and the effect of electromagnetic noise can be reduced.

摘要： In the magnetic absolute encoder, an ordinary operating circuit and an ordinary/backup operating circuit are actuated during ordinary operation in which power is supplied from the ordinary operating power supply; the single-rotation absolute value (1) and single-rotation absolute value (2) detected by these circuits are compared by the abnormality diagnosis circuit, and the presence or absence of an abnormality is automatically judged During backup in which the ordinary operating power supply is interrupted, only the low-power-consumption ordinary/backup operating circuit is actuated, and the multiple-rotation value (2) is detected At the point in time at which the system is returned to ordinary operation, the multiple-rotation value setting circuit sets the multiple-rotation value (2) as the multiple-rotation value (1) of the ordinary operating circuit. As a result, the calculation operation of the multiple-rotation value (1) can be restarted.

摘要： A multiple-rotation absolute encoder attached to an actuator provided with a motor and a reduction gear comprises a multiple-rotation value counter for counting a multiple-rotation value representing a number of rotations of a rotating shaft of the motor from a predetermined origin; a memory part for storing a reduction ratio R of the reduction gear; and a counter-controlling part for setting a range of the count value of the multiple-rotation value counter from zero rotations to (R−1) rotations on the basis of the reduction ratio R stored and maintained in the memory part, resetting the count value to zero when the rotating shaft makes a single rotation in a forward direction from a state in which the count value is (R−1), and setting the count value to (R−1) when the rotating shaft makes a single rotation in a reverse direction from a state in which the count value is zero. The rotation-angle position within a single rotation of the output shaft can be specified without the multiple-rotation value counter overflowing, even when the actuator rotates continuously in one direction.
