A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

The valves, which can move from fully-open to fully-closed in as little as 30 msec, reportedly can fit in a fraction of the package space ordinarily needed for comparably-rated valves using a linear ...

The two degrees of freedom in movement can be actuated independently or concurrently. The actuators can be run using a two-axis stepper-motor driver and chopper and/or microstepping drives. The Size ...

What an actuator is, and what the difference is between linear and rotary The three main energy types—electric, pneumatic and hydraulic—plus thermal, magnetic and piezoelectric What to keep in mind ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...
