| 197,184 CAN/WDB CONTROL SYSTEM FOR TRANSDUCER POSITIONING MOTOR A control system for a stepper motor utilized in positioning a transducer (18) in relationship to a plurality of parallel tracks (14, 16) on a record media (10). Dual closed loop feedback systems are provided. A current control circuit is provided having a high output impedance and a voltage control circuit is provided having a low output impedance. A switch (30) may select the current control sensor (28) when the transducer (18) is making coarse adjustments in position and may select the voltage control sensor (32) when the transducer (18) is making fine adjustments in position. A seamless switchover may be achieved where the voltage control sensor (32) has a time constant which matches the time constant of the stepper motor. Performance is further improved by providing an impedance cancellation circuit (252, 254, 256, 258, 260, 262) which eliminates the internal resistance of the motor in order to quickly damp motionally induced emf of the motor. | ||||||

| 1477282 Fluid-pressure servomotor systems W VOLKI 12 Feb 1975 [6 March 1974] 6067/75 Heading G3P In a solenoid operated piston valve a throttle 11 is provided in the passageway 6 leading to a work port. When solenoid 8 is actuated to shift the valve to the left the pressure on each side of the throttle is fed to respective ends of the valve to produce a resultant force opposing the opening force of the solenoid. In an alternative embodiment, Fig. 2 (not shown) the throttle is provided within an axial passage in the piston valve. In a further embodiment, Fig. 3 (not shown) passages are provided in the piston so that in the neutral position the inlet (28) is connected to exhaust (24). | ||||||
