The Parallax Feedback 360° High Speed Servo has the functionality of a light-duty servo, continuous rotation servo, high-speed servo, and encoder in one convenient package - what a triple threat! Like most continuous rotation servos, this is controlled by a standard 50 Hz pulse-width-...
As I discussed in the introduction to servos, one of the consequences of hobby servos’ intended use is that rotation range is limited to about 180 degrees. In this post, I will talk about two exceptions to this general rule: continuous-rotation servos
This is a servo winch with a few Watts of power. This winch can easily raise and lower 1 kg.This device uses optical sensors to measure the rotation
A servo drive system of a press machine has a pair of servo motors which can generate necessary ram pressure by compositing and using a torque based on the same speed-torque characteristics. The servo motors are symmetric with each other in a mirror image manner. The servo motors are opposed...
so that the platform may be rotated about one or more axes. A control system for rotation about one of the axes typically includes an actuator such as a torquer, a position sensor such as a resolver, a mechanism for generating position commands, and a closed loop servo for causing the ...
a fast tool servo (FTS) is a solid state piezoelectric (PZT) device, referred to as a PZT stack, which rapidly adjusts the position of a cutting tool attached to the PZT stack. The FTS allows for highly precise and high speed movement of the cutting tool in directions within a coordinat...
The momentary rotation amount of No. 1 servo motor M1 increases or decreases slightly from a previously programmed value, and out of synchronization is generated between the No.1 and No.2 servo motors M1, M2. Accordingly the film feed amount by an upstream feed roller R1 will slightly ...
It contains nine radially arranged linear bellows actuators with rollers that push forward a cam profile. Proportional valves and a rotary encoder are used to control the bellows pressures in relation to the rotation angle. Introducing freely programmable servo pneumatic commutation increases versatility ...
Synchronized image rotation compensation between the focal plane and scanning mirror is achieved using a dual-axis gear linkage and dual-motor servo control method [16]. The accuracy of gear transmission and the dual-motor servo control system proposed in this study is 34'' and 1', respectively...
