摘要： In a method of controlling a servomotor, a high output can be fetched from the servomotor by a motor-current control unit of a simple construction, while protecting switching elements of the control unit against excess current. The deviation between a command current (Ir) for of a plurality of winding portions constituting an armature winding of each phase and a current (Ia, Ib) flowing through each winding portion is integrated by an integrating element (9, 9'). The current (Ia, Ib) is amplified by means of a proportional element (10, 10'), and the individual currents (Ia, Ib) are controlled for substantially independent and equal values by means of one PWM control section (3) operating in response to a control signal which is obtained by adding outputs from both the elements (9.about.10').

摘要： A servomotor velocity control system has an estimating unit (4) for obtaining an estimated value (V) of velocity based on rotary encoder position information (.theta.), which includes a current (I.sub.L) indicative of load torque, and motor current (I) of a servomotor (5). The system is adapted to obtain a torque command signal (U) based on the estimated value (V) of velocity and a velocity comman signal (V.sub.c).

摘要： The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.

摘要： A lens position calculator is provided that determines a phase of a driving signal as a reference position of an imaging lens when an output value of a position detection sensor reaches a threshold value. The lens position calculator determines a position obtained by performing addition or subtraction on the reference position read out from a reference position storage as a judgment position, detects an output value of the position detection sensor at a timing in synchronization with the driving signal that drives a driver and at the judgment position, and judges whether the output value of the position detection sensor at the judgment position reaches the threshold value or not, so as to determine the reference position again.
