The Haydon Switch line of dual-motion actuators provides independent linear and rotary motion from a compact package.
The Haydon Switch line of dual-motion actuators provides independent linear and rotary motion from a compact package and is now available in three frame sizes, Nema 14, 17 and 23.
The actuators are based on patent pending designs and incorporate Haydon's proven motor technology.
These units simplify product development by replacing what would otherwise be far more bulky and complex mechanisms.
Another feature of this design is to provide an electric motor in which linear and rotary motions are controllable independently of one another.
Standard strokes are one, two and four with customised strokes up to six inches possible.
Linear step resolutions range from just 1.5 microns per step to 158 microns per step depending on the model.
A limitless number of operating parameters are offered, allowing each device to be custom manufactured according to customer specific application requirements.
For a rotary/linear motor, it is desirable that the linear and rotary motions be controllable independently of one another.
These devices can be run using a standard two axis stepper motor driver.
Performance can be enhanced using chopper and/or microstepping drives.
In certain applications, it is required to have both rotary and linear motion, for example in the robotic picking and placing of components it may be required to axially move a component to an insertion position and then rotate the component to screw it in place.
Another type of application requiring a shaft, which may selectively rotate and/or reciprocate, is in the precise control of laparoscopic and other such medical instruments.
Haydon's line of dual-motion actuators provides independent linear and rotary motion from a compact package.
A complementary range of hybrid and can stack linear and rotary stepper products and a comprehensive range of leadscrews are also available from UK agent Servotechnic.
