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 ...

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now produced a light driven rotary motor in which ...

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 ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Achieving a similar reversal of direction of rotation in artificial molecular motors presents a ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...
