摘要： A digital servo system which is featured by improved precision in the ''halt'' position. A position detection means (1) counts +1 or -1 every time when an object is moved by a predetermined distance, and sends the position of the object to a position error detection means (2). The error relative to a position command value obtained by the position error detection means (2) is sent to a velocity command generation means (3), where it is processed into velocity command. To the velocity command is added by a velocity command offset addition means (8) an offset value having an absolute value smaller than a minimum velocity command value. A motor (40) is driven on the velocity command that is added to the offset value.

摘要： A digital servo system capable of quickly bringing an object having a small frictional resistance into halt at a position where it is to be stopped without generating vibration. A velocity command generation means (3) calculates a velocity command value (Vcmd) from a deviation between a position feedback and a position command value detected by the position deviation detection means (2). A velocity deviation detection means (5) calculates a deviation (E) between the velocity command value (Vcmd) and a velocity feedback. A torque command generation means (6) calculates a torque command value (Tcmd) obtained by delaying the deviation (E), and sends it to a motor drive means (7).

摘要： In a device for coupling a servo motor (10) which has a motor housing (12) and an output shaft (20) rotatably supported by the housing, to a rotary detector (32) which has a detector housing (34) and an input shaft (36) rotatably supported by the housing (34), the output shaft and the input shaft are rigidly clamped coaxially by a shaft clamping bolt (56). The motor housing and the detector housing are coupled by an annular leaf spring (64) extending around the circumferences thereof, concentrically with the output and input shafts. The spring is attached by a plurality of housing clamping bolts (66) to both of the motor and detector housings, thereby allowing a relative axial displacement of the motor and detector housings while suppressing any relative rotational displacement.

摘要： In order to provide an electromagnetic brake (24, 26, 27, 30) in a motor, a brake core (30) must be correctly positioned with respect to the output shaft (10) of the motor. So far, therefore, the bottom surface (18A) of the core housing (18) to which the brake core (20) is secured and the bottom surface (20A) of the brake core (30) have to be machined highly precisely, resulting in an increase in the cost and making it difficult to decrease the size. According to the invention, the brake core (30) and the core housing (28) are formed integrally as one piece by injection-molding plastic material to decrease after-treatments. Thus a compact motor having a built-in electromagnetic brake can be provided.

摘要： It is necessary in a rotor, one of the essential constituents of a motor, that the torque generated in a rotor body (10) thereof be transmitted to an output shaft (12). A transmission gear consisting of end plate members (13) and bolts (16) is used for this purpose. Each end plate member (13) is made by laminating a required number of annular sheet metal members (14) obtained by punching a suitable sheet metal. Holes (24) for the bolts (16) and a central hole (22) having a cross-section similar to that of a spline shaft are punched in each annular sheet metal member (14). The bolts (16) are passed through the holes (24) so as to fix the end plate members (13) to the rotor body (10), and a spline portion (20) formed on the output shaft (12) is engaged with the central hole (22) to form a rotor.

摘要： An AC servo motor employs as a portion of a motor housing the outer peripheral surface (21b) of a stator core (21) formed by laminating thin steel sheets (22). A pair of brackets (25, 26) are respectively attached to the front and rear ends of the stator core (21). Bearing members (27, 28) are respectively provided on the brackets (25, 26). In the manufacture, after the brackets (25, 26) have been firmly secured to the stator core (21), bearing mounting bores (25a, 26a) and motor mounting surfaces (25b, 25c) are machined so as to be concentric and perpendicular with reference to the axial bore (21a) and the outer peripheral surface (21b) of the stator core (21). Thus, a rotor (29) is assembled through the bearing members (27, 28) such as to possess highly accurate concentricity with respect to the stator core (21). In addition, the perpendicular relation between the motor mounting surfaces (25b, 25c) and the output shaft (29a) is ensured.

摘要： A method of removing follow-up delay in a full-close feedback NC system, wherein an instruction signal is corrected in the following manner when the direction of movement is inverted. That is, when a backlash quantity in the mechanical system is denoted by DELTA X, a position gain of the servo system by Pg, and a correction coefficient by K, the correction quantity (Xc) is determined to be K. DELTA X, and the correction time (Tc) is determined to be l:Pg:K. This correction makes it possible to control the position of the table of a machine tool maintaining high precision and permitting little error in position to develop.
